Our History

Tri-State Memorial Hospital & Medical Campus


As the only not-for-profit, community owned and operated hospital in the Lewis Clark Valley, we take special pride in making sure your health is our first priority! Over sixty years ago, a group of dedicated community members set out to build a new, larger hospital that could serve the community and surrounding areas for years to come. Today, the Board of Directors, administration, staff, and providers at Tri-State Memorial Hospital & Medical Campus continue that legacy by serving a 10-county region in Washington, Idaho, and Oregon.

Tri-State Memorial Hospital & Medical Campus is located at 1221 Highland Avenue in Clarkston, WA with 7 acres available for expansion. In addition to the hospital, the campus includes various physician offices, Pathologists’ Regional Laboratory, Owl Tri-State Pharmacy and Evergreen Estates Retirement & Assisted Living Community, an independent and assisted living center located directly behind the hospital. The campus also includes the Tri-State Medical Office Building, consisting of several suites which house our medical clinics. Tri-State offers acute care as well as a DNV GL Healthcare USA accredited critical access facility, and is committed to providing the high-tech medical treatment you expect with the tender touch and personal attention you deserve.
