What is now known as Tri Valley Health System began over 60 years ago with the opening of Cambridge Memorial Hospital in 1958. With the assistance from a Hill-Burton grant, a fund drive by area residents, and a bequest from John Decker, the dream of creating a hospital to service Furnas County and the surrounding area was realized.
The hospital quickly grew and expanded with medical clinics throughout Furnas County and eastern Red Willow County. In the early 1990's, the health network again expanded services to include senior care and housing and became Tri Valley Health System. In the years since, Tri Valley Health System has been recognized by the Wall Street Journal as a model for integration of services and also added Tri Valley Diagnostic Sleep Center.
On October 3, 2010, Tri Valley Health System celebrated yet another expansion with the grand opening of a new state-of-the-art facility to house Cambridge Memorial Hospital and Cambridge Medical Clinic. The original hospital complex was renovated in March 2011 to create Tri Valley Healthy Living Center. This space is dedicated to healthy living and disease prevention with amenities such as the Wellness and Rehab Center, Cornerstone dining area, Nutrition and Diabetic services, and education rooms. Tri Valley Healthy Living Center also allowed for a new location for the Tri Valley Diagnostic Sleep Center.
