Magan Medical Clinic, Inc. was founded in 1919 by Dr. W.P. Magan, Sr. From 1923 to 1967 the Clinic was located at 155 West College Street, Covina, California. However, continued expansion of the practice made it necessary to move to a larger facility, and the Clinic moved to its present address October 1, 1967. Again, in 1989, the Clinic expanded the building to its current size. The Clinic building is designed to facilitate efficiency of service by the providers and employees, while providing the greatest convenience to the patients.

In 1978, the Clinic opened a satellite office in Diamond Bar, California and continues to maintain a practice there. Diamond Bar offers Family Practice and Pediatrics five days per week. Magan and the Lawson Medical Group merged in 1993.

In 1990, Magan joined forces with Southland Pediatrics, and we now maintain a satellite office in La Verne, California. Family Practice was added during 1993 to serve more patients in the La Verne area.

In 2007, Magan opened a satellite OB/GYN office, conveniently located on the campus of San Dimas Community Hospital in San Dimas, California, and is open Monday through Friday.

On January 1, 2013, Dr. Gail Campofiore’s family practice in North Covina also joined Magan.

February 1st, 2014 Dr. John Cu, an Internist in West Covina merged his practice with Magan.
