History of Tristar Summit

In the late 1960s, a group of physicians led by surgeon Carl Gessler, M.D., created an alternative to downtown Nashville hospitals that would provide convenient emergency care and the best in diagnostic testing and treatment for their community. To reach their goal, they began working with the newly formed Hospital Corporation of America. Their dream became reality with the 1970 opening of Donelson Hospital.

Originally a 100-bed facility, Donelson Hospital expanded numerous times in its 21-year history to continuously meet the healthcare needs of our growing service area. The construction and 1994 opening of the new Tristar Summit was the fruition of the founding doctors' vision. Today, the 196-bed Tristar Summit stands as a tribute to the proud and successful history of Donelson Hospital.
