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.To learn more, visit www.TSH.org
