The property, purchased by the State of Texas in 1935, previously served as other healthcare facilities before 1951. The
dude ranch My Ranch operated here at the beginning of the 20th century; it began its life as a healthcare area in 1915. From 1915 to 1917 the tuberculosis hospital Mountain Park Sanitorium occupied the site, and from 1917 to 1935 Thompson Sanitorium, run by Dr. Sam E. Thompson, occupied the site. From 1935 until a few years later, it served as a state treatment center for black people with tuberculosis. In 1951 it opened as a Kerrville branch of a state mental hospital located in
San Antonio. In 1952 it became the Kerrville State Hospital, its own institution. Originally it only served residents of specific counties in the
Texas Hill Country. The largest treatment building opened in 1992; it houses ten treatment programs. ==References==
