Improving the health and wellness of the communities we serve


The healthcare District has a rich history that has been well documented over these forty-plus years. Envisioned and built by the community, the District has served as a healthcare safety-net in the Morongo Basin.

We are currently working on presenting the time line and photos for your reference. Thank you for your understanding and patience as we work to make our history available to you.

Late 1971:
The County Formation Commission ordered the consolidation of the Yucca Valley Hi-Desert Memorial Hospital District and the Twentynine Palms Community Hospital District in what observers referred to as a “shotgun” wedding.” At the time of the consolidation, preparations were underway at both ends of the Morongo Basin to renovate the individual hospital – revenue bonds for a 28-bed facility had been passed in Twentynine Palms, and Yucca Valley voters passed an $8.6 million revenue bond issue, purportedly on a site between Joshua Tree and Yucca Valley. Soon after, the consolidation of the federally charted Inland Counties Comprehensive Health Planning Council ruled there should be one centrally located hospital. Opposition emerged in various forms to the proposed new medical center and residents, particularly in the west end of the valley, mounted a number of strategies against it, including alternate private hospital proposals and opposition to approval of the center before various county, regional and state agencies – all to no avail. When the State Attorney General refused to grant residents permission to pursue the matter in the courts a few months later, construction of the new hospital moved out of the political arena and onto its present White Feather Road site.

Feb 23, 1975:
Groundbreaking Ceremony: Bob Thacher and Larry Fine were co-masters of ceremony; 400 were in attendance. Mr. Thacher was serving as the U.S. Magistrate and represented Twentynine Palms. They borrowed a semi-truck from the Base and set it up as the stage where the main entrance of the hospital would be. Edward Lincoln Smith, MD, and his mother were honored guests. Dr. Smith had been the only physician in the area for many years. Judge John Allen, who preceded Mr. Thacher as U.S. Magistrate (it was then called Commissioner) was one of the driving forces in getting a single hospital in Morongo Basin and had served on the Board of the Twentynine Palms Hospital. 75 folding chairs were set up in front of the truck stage. The hospital board members manned the shovels: Walters, Petrovich, Emrick, Luckman, and Ishmael.
