The Tilden School for Teaching Health operated from 1916 to 1931 as a private residential teaching institution and sanitarium that offered patients an alternative to the standard medical practices of the day. Located in Denver, Colorado, the school was established to teach and promote the medical theories of its founder, Dr. John Henry Tilden.

Tilden believed that toxemia, the build up of toxins and waste in the body, was “the universal cause of all diseases”. He believed that only a strict adherence to his dietary principles, a prudent lifestyle and proper hygiene would restore health and cure all illness. Tilden's techniques taught at the school included fasting, prescribed menus of carefully balanced food combinations, restrictions and rules on liquid intake, the necessity of fresh air and sunshine, colonic cleansing, rest and the elimination of stress both mental and physical. His philosophy of the body healing itself rather than outside interventions such as drugs or surgery foreshadowed modern naturopathy.

Tilden promoted his school and views through lecture tours, books, articles and a series of journals under the titles A Stuffed Club (1900 - 1915), Philosophy of Health, and Dr. Tilden's Health Review and Critique (1926-40) The school was advertised as the place "where thousands 'Hopelessly Ill' get well without drugs, serums or surgery."

The Tilden School for Teaching Health attracted patients from all over the country and world including Canada, Great Britain and Australia. It offered furnished apartments for its patients to learn to take care of themselves and practice the Tilden techniques for healthy living. As many of his patients stayed for extended periods of time, the school's architecture and grounds were designed to invoke more of an ambiance of a residential apartment complex as opposed to a traditional medical facility.

Summer months were the busiest for the school as patients were attracted by the pleasant summer Colorado climate. At its peak, the Tilden School housed eighty five patients with a staff of thirty employees. For those who could not travel to the school, Tilden offered his consultation and prescribed diets via mail for $50 per month.

Tilden was involved in the operation of the school until 1924 when he sold most of his interest in the enterprise to Arthur Vos, Andrew Jergens (heir to the Jergens Soap Company fortune) and Frank C. Adams for $150,000. It is unclear if this is when the name was shortened to the Tilden Health School. In December 1924, after a falling out with the new owners, Tilden parted ways with the school and in 1926 opened a new operation in east Denver called the Tilden Health Institute. He operated the Institute until his death in 1940.

Vos operated the Tilden Health School until 1931, when the effects of the Great Depression forced its closure. Vos's son, Arthur Vos, Jr. was appointed receiver of the property by the Denver District Court.

Eventually the campus was divided up and sold to separate entities.
