How Do Our Patients Feel About Us?
"Excellent Clinic! The staff were very helpful and polite from my initial phone call to every appointment day. All the doctors are friendly and knowledgeable. They took the time to explain my condition and my treatment options. Glad to find this clinic who can finally end my back pain!" Susan B.
"Dr. An is great and so is her staff. I saw her about 24 hours after an ankle injury - she recommended PRP injections. Now it's 3 days after the PRP treatment and I'm back to teaching and practicing yoga. I highly recommend Campbell Health Center." Hope W.
