From Monday to Friday, the ASM Clinic provides primary healthcare consultations at its Main Clinic on Peebles Farm, situated on the Numbi Gate Road between White River and Hazyview. The Main Clinic also serves as the operational base from which all mobile clinic outreaches are conducted. 

The clinic primarily serves communities living in the nearby Masoyi Tribal Trust area, as well as members of the various missionary organisations based in the region. Over the years, however, the Clinic has earned a reputation for providing compassionate, high-quality medical care. As a result, patients now travel from distances of 100 km or more to access its services.

Many local patients present with complex or advanced medical conditions that were not recognised or were inadequately managed elsewhere. Consequently, the ASM Clinic is often regarded by the surrounding communities as a referral point for difficult or complicated primary healthcare cases, providing careful assessment, accurate diagnosis, appropriate treatment, and referral to higher levels of care when required.
