Our Story
Our Roots
Medical Gas Services was founded on a simple observation: in the Pacific Northwest, medical gas verification was being treated as a convenience, not a critical path item. Reports were slow, inconsistent, and often left facilities exposed.
Our team holds one of the broadest medical gas certification portfolios in the region — from ASSE 6010 installation through ASSE 6060 system design — backed by 17+ years of specialized experience.
Today we serve hospitals, surgery centers, endoscopy clinics, specialty facilities, and MEP contractors across Washington, Oregon, Idaho, and Alaska. We show up prepared, deliver reports on time, and answer the phone when you need us.
