TriState Health

About TriState Health

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 TriState Health continue that legacy by serving a 10-county region in Washington, Idaho, and Oregon. We are a not-for-profit, community-owned hospital (since 1955), offering acute care as well as a DNV GL Healthcare USA accredited critical access facility. We are committed to providing the high-tech medical treatment you expect with the tender touch and personal attention you deserve. TriState Health is located on 11 acres at 1221 Highland Avenue in Clarkston, WA with 7 acres available for expansion. In addition to the Hospital, the campus includes various physician’s 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 TriState Medical Office Building, consisting of several suites which house our medical clinics.
