[3] On June 14, 2023, the complex known as Mid-Columbia Medical Center (MCMC) for forty years was purchased by Adventist Health.

Belle Cooper Rinehart Ferguson gave high praise to her mother, "…whose encouragement, intelligence and ability imparted strength and determination."

In 1979, twenty years after opening, the hospital expanded by 20,000 square feet (1,900 m2) to accommodate more patients with more beds and other improvements.

In 1983, Ancillary service departments are remodeled and the hospital changes its name to Mid-Columbia Medical Center (MCMC) to more accurately reflect its emergence as a regional resource for comprehensive healthcare.

In 1990, Dr. Bill Hamilton and Dr. Hal Sessions performed the first laparoscopic gall bladder surgeries in the Columbia River Gorge at MCMC.

In 1992, MCMC's remodel is complete, transforming the traditional hospital into a comfortable "center of healing" and ushering in the Planetree era.

[5][6] In 2013 it was reported by an anonymous social worker in Hood River, Oregon, that the primary reason for the majority of bankruptcies filed in the Mid-Columbia area were medical bills incurred at MCMC.
