Since 2023, he has led as CEO, emphasizing technology-enabled affordable coverage, and in October 2025, he assumed the role of chairman at Verizon Communications Inc. Known for his unconventional style—marked by tattoos, a preference for leather jackets, and self-identification as a "radical capitalist"—Bertolini prioritizes first-principles innovation in addressing systemic inefficiencies in U.S. healthcare, such as advocating for the phase-out of employer-sponsored insurance to enhance market competition and consumer choice.

Early life and education

Childhood and family background

Mark Bertolini was born in 1956 in , , and raised in a blue-collar family in the nearby suburb of St. Clair Shores. He was the eldest of six children—siblings including John, Peter, Angela, Nina, and Phillip—born to Raymond George Bertolini, who owned an auto repair shop, and Catherine Theresa Bertolini; the family lived in a boisterous, cramped household amid modest means reflective of Detroit's working-class environment during the mid-20th century. Bertolini's early upbringing emphasized hard work and resilience, lessons instilled by his father through hands-on labor at the family auto shop, where as a teenager he earned $1.25 per hour performing tasks such as cleaning toilets, washing floors, painting walls, and cutting lawns. A pivotal anecdote involved Bertolini, at age 14, demanding a raise from his father, resulting in his firing; he was later rehired at a reduced $1 per hour after reflecting on the incident, which taught him against entitlement and the importance of —never quitting without another opportunity lined up. His father also highlighted for workers' circumstances, citing a co-worker named Jerry who earned $4.25 per hour to support his family, underscoring the value of fair effort over complaints. As the first in his family to pursue higher education, Bertolini's childhood experiences in this industrious, resource-constrained setting shaped his later professional ethos.

Academic and early influences

Bertolini attended in , where he pursued studies in , ultimately earning a degree. His undergraduate path was marked by significant challenges, including dropping out twice, which extended his time to completion over eight years. Despite these setbacks, he persisted, reflecting a determination shaped by early lessons in hard work instilled by his father, who emphasized the value of diligence through personal example in a working-class environment. Following his undergraduate degree, Bertolini obtained a with a focus on finance from Cornell University's Johnson Graduate School of Management, graduating at the top of his class in 1983. This academic achievement positioned him for competitive opportunities, including offers from firms, yet he opted for a path in healthcare, influenced by prior hands-on experience as a during his twenties. The role exposed him to the frontline realities of medical emergencies and the inefficiencies within the , fostering an early pragmatic orientation toward operational challenges in care delivery rather than abstract financial pursuits. These formative academic experiences, combined with real-world exposure, cultivated Bertolini's approach to problem-solving, prioritizing empirical outcomes over theoretical models—a evident in his subsequent career decisions to tackle underperforming health organizations. While institutional sources like university records affirm his degrees, personal accounts in interviews highlight how overcoming academic hurdles reinforced resilience, influencing his later for adaptive, results-driven strategies in .

Professional career

Early roles in health insurance

Bertolini entered the industry in 1985 after earning a in accounting from . His early career included executive positions at Cigna Corporation, where he managed aspects of national sales and delivery networks for healthcare products. He advanced to Executive Vice President at NYLCare Health Plans, a provider of services in select markets, focusing on operational and strategic oversight during a period of industry consolidation in the 1990s. Prior to joining in 2003, Bertolini served as President and of SelectCare, Inc., a Michigan-based , where he directed efforts to build statewide provider networks and compete with established insurers like Blue Cross Blue Shield. These roles honed his expertise in economics, provider contracting, and market expansion amid rising healthcare costs and regulatory changes.

Leadership at Aetna

Mark Bertolini assumed the role of Chief Executive Officer of Aetna Inc. on November 29, 2010, and Chairman on April 8, 2011. During his tenure, he led the company through a period of strategic transformation, emphasizing consumer-oriented healthcare and value-based care models to adapt to evolving market dynamics. Bertolini co-authored the 2015 Harvard Business Review article "Knowing When to Reinvent," which outlines a framework for detecting "fault lines"—early signals of marketplace disruption—in five key areas: industry position, customer needs, performance metrics, business model, and talent/capabilities. The framework advocates proactive reinvention, even during periods of strong performance, to avoid obsolescence, as exemplified by Aetna's successful adaptations contrasted with failures like Kodak's. Key initiatives included enhancing preventive health programs and operational efficiencies to address rising medical costs. Bertolini oversaw significant acquisitions to expand Aetna's footprint, notably the $5.7 billion purchase of Coventry Health Care announced in August 2012 and completed in May 2013, which added approximately 5 million members, including nearly 4 million medical members and strengthened Medicare and capabilities. An attempted $37 billion acquisition of in 2015 aimed to further bolster consumer-focused services but was blocked by antitrust regulators in 2017. These moves contributed to revenue growth, with quarterly operating revenue reaching nearly $16 billion by the second quarter of 2016, and full-year of $2.3 billion in 2016 and adjusted of $3.3 billion in 2017. In employee relations, Bertolini implemented progressive wellness policies, including mandatory training, , and classes, which reportedly reduced employee stress and associated healthcare costs by about $1,500 per worker annually. He raised the for the lowest-paid employees by 33% to $16 per hour in 2014, aiming to improve retention and productivity amid broader cost-control efforts. However, to manage fiscal pressures, such as potential impacts from the 2012 fiscal cliff and rising operational expenses, Aetna under Bertolini considered and executed workforce reductions, including layoffs and scaling back telecommuting policies in 2016. Bertolini's leadership culminated in Aetna's acquisition by in November 2018 for $69 billion, marking a substantial increase in shareholder value with the company's stock rising approximately 600% during his tenure. His approach blended aggressive cost management with innovative employee health strategies, though it drew scrutiny over claim denial practices and market exits from exchanges due to unprofitability. Overall, these efforts positioned Aetna as a more integrated and efficient player in the sector prior to the merger.

Transition to Oscar Health

Following his tenure as co-CEO of from January 2022 until April 2023, Mark Bertolini transitioned to the sector by joining as , effective April 3, 2023. The appointment, announced on March 28, 2023, replaced co-founder and outgoing CEO Mario Schlosser, who shifted to the role of President of Technology to concentrate on product innovation and platform development. Bertolini's selection aligned with Oscar Health's need for operational scaling expertise, drawing on his prior leadership at , where he served as CEO from November 2010 to November 2018 and oversaw the insurer's shift toward consumer-centric models emphasizing value-based care and digital tools. He articulated his return to healthcare as driven by a belief that substantial reforms remained incomplete, particularly in enhancing consumer choice and efficiency within the U.S. system. Oscar's board chair, Jeffery Boyd, highlighted Bertolini's track record in navigating complex mergers and fostering growth as key to positioning the company for long-term viability amid its challenges with profitability post-IPO. The move supported Oscar Health's ambitions as a technology-first insurer, founded in to simplify coverage through data and member-facing apps, by integrating Bertolini's industry acumen with the firm's tech infrastructure. Early under his guidance, Oscar pursued expansion into employer-sponsored plans and individual coverage health reimbursement arrangements (ICHRAs), targeting small and mid-sized businesses to diversify beyond individual marketplaces. These initiatives marked a strategic pivot to stabilize finances, with the company reporting progress toward profitability by mid-2024.

Healthcare policy views

Critiques of government intervention

Bertolini has argued that the (ACA), enacted in 2010, created an unstable in markets by distorting risk pricing through mandates like guaranteed issue and community rating, which limited premium variations to no more than threefold between younger and older enrollees, leading to where healthier individuals opted out due to unaffordable costs. This imbalance resulted in insufficient enrollment—about half of the projected 13 million in exchanges by 2016—and a skewed pool favoring higher-risk individuals, prompting average premium hikes of 23 percent for 2017, with some markets exceeding 58 percent. In response, under Bertolini's leadership reduced participation in ACA exchanges from 15 states in 2016 to just four by 2017, citing projected losses exceeding $300 million from inadequate risk pools and insufficient federal risk adjustment payments. He described the individual market under the ACA as approaching a "death spiral" in early 2017, characterized by escalating premiums and insurer exits that further deterred healthy enrollees. Bertolini further critiqued government antitrust interventions, such as the Department of Justice's 2017 blockage of Aetna's proposed $37 billion acquisition of , as impeding necessary consolidation to achieve scale and cost efficiencies in a fragmented industry. Bertolini has consistently opposed fully government-run healthcare systems, stating in that "government-run healthcare would be a bad idea," arguing that such models fail to leverage and efficiency, as evidenced by inefficiencies in programs like Medicare. He has also highlighted how federal tax policies favoring employer-sponsored insurance—exempting premiums from income and payroll taxes—distort consumer choice by tying coverage to employment, reducing portability and market competition while insulating individuals from true costs. These interventions, in his view, perpetuate a reactive, cost-escalating system rather than promoting preventive, individualized care.

Advocacy for market-driven reforms

Bertolini has consistently argued that transitioning the U.S. health insurance system toward a dominant individual market, rather than employer-sponsored group plans, would enhance competition, reduce costs, and increase . In a December 2024 interview, he proposed eliminating traditional employer-based coverage while maintaining employer contributions, allowing workers to select personalized plans on the individual market to better align with their needs and preferences. This approach, he contends, addresses systemic inefficiencies in group plans, which often limit innovation and portability, by empowering consumers to drive market dynamics through direct purchasing. He highlights the individual market's rapid growth—described as the fastest-expanding segment of —as evidence of its potential to deliver affordability and quality, particularly when supported by tools like Individual Coverage Health Reimbursement Arrangements (ICHRAs). ICHRAs enable employers to reimburse employees for individual policies, potentially expanding access for small businesses and underserved groups without the distortions of mandated group benefits. Under his leadership at , Bertolini has prioritized this market, projecting it could capture a larger share by leveraging technology for price transparency and customized coverage, contrasting it with stagnant employer plans that he views as relics of post-World War II wage controls. Bertolini's advocacy extends to critiquing government interventions like the (ACA), which he has called a "death spiral" to , where healthier individuals , leaving insurers with costlier risks and up premiums. He advocates market-oriented fixes, such as enhancing competition across state lines and reducing regulatory , over further expansions of mandates or subsidies that he argues entrench monopolistic behaviors among large providers and insurers. While acknowledging potential tweaks to the ACA, such as broader Medicare access for younger adults to stabilize risk pools, his core stance favors to unleash consumer-driven reforms, positioning the individual market as the pathway to sustainable, lower-cost coverage.

Personal philosophy and experiences

Impact of family health crises

In 2003, Bertolini's son underwent treatment for cancer, an experience that exposed the family to the limitations of the U.S. healthcare system's focus on over long-term recovery and support. This ordeal, combined with subsequent challenges, prompted Bertolini to question the adequacy of institutional responses to patient needs beyond initial diagnosis and intervention. The following year, on January 19, 2004, Bertolini himself suffered a catastrophic skiing accident at in , where he collided with a , fell approximately 60 feet into a , and sustained multiple fractures including his (C6-C7 vertebrae) and back, along with , nerve damage, and brain trauma. He was placed in a medically for a week, faced permanent partial paralysis in his left arm, and endured chronic so severe that he contemplated during rehabilitation. These crises profoundly reshaped Bertolini's , fostering a deeper for and critiquing the healthcare system's emphasis on treatment over holistic rehabilitation and preventive wellness. As a navigating insurer denials and inadequate post-acute support—despite his executive status—he recognized systemic failures in addressing chronic conditions and recovery, which informed his later advocacy for integrating alternative therapies like and into corporate health benefits. Bertolini credited these events with transforming his leadership style toward "radical capitalism," prioritizing employee well-being and market-driven to address what he saw as misaligned incentives in models.

Embrace of integrative health practices

Following a severe skiing accident on December 24, 2004, in , Bertolini sustained multiple fractures to his neck, a severed in his fifth cervical , and partial in his right arm, resulting in and long-term . During recovery, conventional treatments proved insufficient, leading him to explore integrative approaches including , which alleviated his when traditional painkillers did not, as well as and to address both physical and mental trauma. Bertolini has stated that these practices not only restored his functionality but also prevented amid profound suffering, marking a shift from toward endorsing complementary therapies alongside standard medical care. As 's CEO from November , Bertolini integrated these experiences into corporate wellness, launching a program in developed with Duke Integrative Medicine and eMindful, offering free weekly and classes to up to 50,000 employees. The initiative included 90-minute guided sessions and provided $25 incentives per class attended, with Aetna reporting a 28% reduction in employees' stress symptoms, 62 fewer sick days annually per participant, and estimated healthcare cost savings of $3,000 per employee yearly based on internal metrics. He extended coverage for such practices to policyholders, insuring , , and as reimbursable services to promote preventive, holistic health over reactive treatment. Bertolini's advocacy emphasizes evidence from personal outcomes and pilot data, arguing that integrative practices reduce reliance on pharmaceuticals and address root causes like stress, though he acknowledges the need for rigorous validation beyond anecdotes. In public statements, he has critiqued siloed conventional for overlooking patient-centered alternatives, positioning these methods as cost-effective complements that enhance resilience, as evidenced by his own recovery and Aetna's employee improvements. This approach persisted post-Aetna, influencing his role at , where he continues promoting holistic elements in health plan designs.

Controversies and criticisms

Aetna operational practices

During Mark Bertolini's tenure as CEO of from 2010 to 2018, the company's operational practices in claims processing drew significant scrutiny, particularly regarding and denial procedures. In a 2017 deposition related to a filed by Gillen Washington, former Aetna medical director Dr. Jay Iinuma testified that he approved or denied claims without reviewing patients' full medical records, instead relying on summaries prepared by nurses as part of standard training and workflow. Iinuma specifically admitted to denying Washington's request for intravenous immunoglobulin treatment for chronic variable immunodeficiency without examining the records, contributing to allegations of reckless benefit withholding. maintained that such practices involved reviewing pertinent file sections rather than entire documents to manage high volumes, and Iinuma later clarified in a supplemental statement that he considered relevant portions provided by staff. This testimony prompted U.S. Senators and to send a letter to Bertolini on February 28, 2018, demanding detailed information on 's claims review processes, including the number of claims handled and denied by Iinuma and other medical directors over the prior five years, staff training protocols, and compliance with requirements for fair appeals and record access. The senators expressed concerns that superficial reviews could violate federal consumer protections and enable wrongful denials, citing Washington's case where also allegedly withheld the denial rationale document. At the time, six state insurance regulators were investigating 's prior authorization methods, building on prior penalties such as a $256,500 fine in 2009 for inadequate claims handling in . defended its operations as efficient and compliant, emphasizing nurse-led initial reviews integrated with director oversight to balance cost control and care access. Bertolini's leadership also involved aggressive cost-management strategies, including workforce reductions in specific divisions. In January 2015, Aetna eliminated positions in its unit despite a company-wide minimum wage increase to $16 per hour, as announced by Bertolini during an internal where he assured no broad layoffs were planned. Earlier, in November 2012, Bertolini publicly warned of potential layoffs at if failed to avert the fiscal cliff through a deficit-reduction deal, attributing the threat to uncertainty over reimbursement rates. These measures aligned with broader efforts to streamline operations and improve profitability, which rose under his tenure through premium adjustments and efficiency gains, though critics argued they prioritized financial metrics over service quality. Another operational controversy centered on Aetna's 2017 decision to withdraw from marketplaces in 17 states, affecting over 1 million customers, which some lawmakers accused of being retaliatory following the Department of Justice's blockage of Aetna's proposed merger with . Bertolini refuted claims of a "power play," asserting the exits stemmed from sustained financial losses exceeding $200 million annually in those markets due to and regulatory pressures, rather than merger-related leverage. This strategic retrenchment reflected Aetna's focus on sustainable lines of business but fueled debates over insurer accountability in public exchanges.

Ideological and political stances

Bertolini describes himself as a radical capitalist, emphasizing a reformed version of capitalism that prioritizes mission-driven leadership, employee welfare, and long-term societal benefits over short-term shareholder gains. In his 2019 book Mission Driven Leadership, he argues for reinventing capitalism to address its perceived failures, such as inadequate investment in workers and education, warning that without evolution, younger generations' preference for socialism—evident in polls showing 65% of those under 35 favoring it in 2017—could prevail. He has criticized "broken" capitalism for paying lip service to social issues while failing to deliver holistic healthcare and economic mobility, advocating instead for businesses to treat employees as stakeholders through measures like wage increases and wellness programs. Politically, Bertolini has maintained a bipartisan approach in his contributions, donating a total of $192,847 across 22 transactions in the 2020 election cycle to recipients including both Republicans, such as Donald Trump, and Democrats. For instance, he contributed $5,600 to Amy McGrath's Democratic Senate campaign challenging Mitch McConnell in April 2020. This reflects a pragmatic business orientation rather than strict partisan loyalty, though he publicly distanced himself from Trump in August 2017, stating in an internal memo that he was "ashamed" of the president's behavior and comments following the Charlottesville events, which prompted his resignation from White House business councils. On policy, particularly healthcare, Bertolini favors market-driven reforms emphasizing individual insurance markets and competition over employer-sponsored plans, which he argues distort incentives and limit portability; in December 2024, he proposed eliminating employer insurance to foster a more efficient system. While initially critical of the —describing it as in a "death spiral" in February 2017 due to —he later suggested improvements like expanding Medicare access to younger adults and urged open debate on single-payer models in May 2017, provided they clarify government versus private roles. These stances underscore a preference for empirical, incentive-based solutions grounded in private enterprise, tempered by acknowledgment of government intervention's potential role in addressing market failures.

Legacy and recent developments

Industry influence and achievements

Bertolini's leadership at Aetna from 2010 to 2018 emphasized cost discipline and employee-centric innovations, transforming the insurer into a more efficient operation amid rising healthcare expenses. He implemented progressive workplace policies, including raising the to $16 per hour in 2014, expanding health benefits, providing repayment assistance up to $1,500 annually for full-time employees, and introducing and programs following his personal experiences with integrative medicine. These measures correlated with improved and , as Aetna reported reduced and healthcare claims among participants. Under his tenure, Aetna grew to serve approximately 46 million members and pursued strategic expansions, such as advocating for value-based care models to disrupt traditional practices. His influence extended to policy advocacy, where he supported retaining core provisions like protections for pre-existing conditions while critiquing exchange implementations and pushing for Medicare payment innovations to incentivize preventive care. Bertolini's efforts earned industry recognitions, including Modern Healthcare's 100 Most Influential People in Healthcare in 2017 and 2018, Fortune's World's 50 Greatest Leaders in 2015, and Politico's 50 list in 2015. These accolades highlighted his role in reshaping insurer strategies toward consumer empowerment and data-driven efficiencies. At , where Bertolini assumed the CEO role on April 3, 2023, he has steered the company toward a technology-centric model emphasizing individual market coverage over employer-sponsored plans to enhance portability and competition. He argues that phasing out employer insurance could address systemic inefficiencies, such as job lock and uneven risk pools, potentially lowering premiums through broader market dynamics. Under his guidance, Oscar has expanded its focus on digital tools and value-based outcomes, aligning with his vision of a consumerized system as detailed in his 2019 book Mission-Driven Leadership. This approach positions Oscar to capture growth in individual and small-group segments, reflecting Bertolini's broader impact on promoting market-driven reforms in .

Ongoing role at Oscar Health

Mark Bertolini has served as Chief Executive Officer of Oscar Health since April 2023, leading the company as a technology-driven health insurer focused on accessible and affordable care. Under his direction, Oscar has emphasized consumer-oriented strategies, including enhanced transparency in pharmacy benefits and favorable pharmacy benefit manager contracts, such as the agreement with CVS Caremark extending through 2026. Bertolini's leadership has driven Oscar toward profitability, with the company reporting $178.9 million in for the first nine months of 2024, compared to a $120 million loss in the same period of 2023, and projecting full-year net profitability for 2024 despite a $54 million Q3 loss. Revenue grew 68% to $2.4 billion in Q3 2024, with full-year projections raised to $9.2–9.3 billion, supported by membership expansion to over 1.6 million individual and small group plan members as of 2024, up from 912,761 a year earlier. He has prioritized growth through cost controls and leveraging the marketplace to target small- and mid-sized employers, promoting individual coverage health reimbursement arrangements (ICHRAs) to facilitate individual health coverage purchases. Looking ahead, Bertolini aims to scale membership to 4 million by 2027, pursuing 20% annual revenue growth and $2.25 per share earnings, by expanding into the small and middle employer market covering 71 million lives. In October 2025, he was appointed chairman of Verizon's board, effective following the current chairman's departure, while maintaining his CEO role at Oscar.
