Highlights from Our Journey

Silver Hill Hospital

Silver Hill Hospital Opens

Dr. John Millet founded Silver Hill with the purpose of not wanting to isolate mentally ill patients from society. Millet chooses a location that combines natural beauty with convenient access to New York, thereby providing a sense of community, a healing connection to the landscape and seasons, and proximity to national transportation and the latest advances in psychiatric practice.

Millet works with another physician, William Terhune, and an English nurse Elvira Parsons to establish what they call the “Silver Hill Inn,” a name reflecting a style of hospitality that respects patients as individuals.

Silver Hill Incorporates

Silver Hill Hospital becomes incorporated as a not-for-profit foundation, overseen by a Board of Directors and the first meeting occurs. 

Dr. William Terhune and his wife become shareholders and the Silver Hill Foundation is formed “for the study and treatment of nervous disorders and also to defray the expense of treatment of some worthy patients, to operate free out-patient clinics, to carry on research, medical and lay education, and a residency program.”

Dr. Terhune is elected President and Dr. Millet is elected Vice President.

Silver Hill Grows

Silver Hill was modernizing, expanding, and continuing to promote the central role of psychiatric treatment in overall health care. As its reputation grew, so did the number of patients who sought treatment. But for the most part, social stigma still kept psychiatric problems hidden behind a cloak of conformity and silence.
