Grosso was born in Washington, D.C. During his childhood, he lived on a farm in Northern Virginia. As a teenager, he lived on Rock Creek Church Road in Petworth.

Grosso graduated from Earlham College with a degree in philosophy. He received a J.D. from Georgetown University Law Center in 2001. Before attending college, Grosso volunteered helping refugees from El Salvador living in Honduras. He also spent a year as a full-time volunteer building a transitional housing program for homeless women in San Antonio, Texas, where he met his wife, Serra Sippel, also a native Washingtonian and president of the Center for Health and Gender Equity.

Grosso worked for D.C. Councilmember Sharon Ambrose working as a clerk for the District's Economic Development Committee. He worked as Chief Counsel to Congresswoman Eleanor Holmes Norton and was a vice president of public policy for health insurance carrier CareFirst for several years.

In 2012, Grosso and six other individuals declared their candidacy for two seats as at-large member of the Council of the District of Columbia. Grosso ran as an independent candidate. In accordance with the District's Home Rule Act, one of the seats up for election that year was reserved for an individual who is not affiliated with the Democratic Party.

During a debate among the four candidates for the at-large council seat, Grosso supported expanding the types of illnesses that qualify for medical marijuana. Grosso said he supported the five-cent tax on disposable bags, and he said he does not support school vouchers. Grosso also said he would vote to censure Councilmember Jim Graham for violations of Metro's code of ethics. In addition, Grosso said he was in favor of speeding cameras, saying that they were important because they slow drivers and save lives. Grosso supports giving tax incentives for private employers to move to the District.

The Washington Post editorial board endorsed Grosso for at-large councilmember, citing Grosso's experience with the economic development committee and knowledge of city government. Council member Tommy Wells and former Council member William Lightfoot endorsed Grosso's candidacy. Grosso also earned the endorsements of the Current Newspapers, the D.C. chapter of the Sierra Club, and Greater Greater Washington.

Grosso won one of two at-large seats on the council with twenty percent of the vote.
