Miles City, MT, February 6, 2026 — One Health announced today the opening of the Milligan Building, a newly rehabilitated Federally Qualified Community Health Center (FQHC) in downtown Miles City. The project received significant support from a $2.5 million grant from The Leona M. and Harry B. Helmsley Charitable Trust, helping expand access to high-quality healthcare services in eastern Montana.
Located in the heart of downtown, the historic Milligan Building encompasses about 26,700 square feet across three floors and features 60 feet of frontage on Main Street. The building is a primary contributing structure in the Miles City Main Street Historic District and is listed in the National Register of Historic Places.
Through a multi-phase rehabilitation project, One Health transformed the Milligan Building into a modern clinical facility offering integrated primary and preventive healthcare services, including medical, behavioral health, and pharmacy services. The facility also incorporates a telemedicine hub, a multidisciplinary clinical training program, and the co-location of Custer County Public Health, strengthening coordination of care for the region.
“One Health’s vision to help create communities where every person can thrive — physically, mentally, and socially — resonates with the Trust’s efforts to ensure that high-quality services should not be determined by your zip code,” said Walter Panzirer, a Trustee of the Helmsley Charitable Trust.
“This new facility represents One Health’s continued commitment to accessible, integrated, and patient-centered care,” said Dr. David Mark, CEO of One Health. “By bringing essential services together in a single location, we are strengthening care coordination while investing in the long-term vitality of downtown Miles City.”
The Milligan Building officially opened to patients on February 3.
