About Us

Granger Medical Clinic is one of the largest independent, physician-owned medical clinic groups in Utah.


Granger Medical Clinic was founded in 1954 by Doctors LaVere Poulsen and Glenn Wilson.

Granger Medical Clinic was founded in 1954 by Doctors LaVere Poulsen and Glenn Wilson. The two providers came together with the hope of better serving the Granger community (now West Valley City) on the west side of the Salt Lake valley. They were the first (and at the time, only) physicians in Utah west of the Jordan River to serve a growing population that had previously needed to travel east to find a provider.

Their practice steadily grew and in 1998, the clinic – then 21 providers strong – moved to a larger building in West Valley City. Continuing its trajectory, Granger Medical Clinic added locations, opening offices in West Jordan, Riverton and Draper. Today, Granger Medical Clinic has become one of Utah’s largest physician-owned medical groups with 28 locations now spanning four counties reaching from Bountiful to Payson and Sandy to Tooele.

Along the way, Granger Medical Clinic has added many specialists and ancillary services to improve convenience and quality of care for its patients. Within Granger Medical Clinic, there are over 170 providers practicing in 29 specialties with other services (including a sleep lab, clinical research studies, a lab and imaging department, and laser cosmetic treatments) being offered.
