Welcome to Riverside Medical Clinic, one of the oldest and most successful healthcare organizations in the Inland Empire. We've been caring for generations of Southern Californians ever since Drs. Phillip Corr and Ray McCarty established a practice modeled after the Mayo Clinic. Their vision was to bring top notch primary and specialty physicians into one group, offering virtually every outpatient service the community might need from a single source. That vision has materialized into the largest private ambulatory healthcare system in the Inland Empire. As the first fully accredited multi-specialty group in the area, Riverside Medical Clinic now serves a community of more than 226,000 with state-of-the-art technology and straight-from-the-heart healthcare
