Meet Gannon Lee, D.D.S.

Dr. Gannon Lee is an Orange County native who has been practicing dentistry for twenty years. Dr. Lee earned his dental degree from the University of Southern California, after earning his bachelor's degree in Biological Sciences from the University of California, Irvine.

After nearly a decade in his private practice in Encinitas, California, Dr. Lee decided to relocate back to Orange County. It was a very difficult decision to leave good friends, patients, and relationships he has built up over the years. However, he and his wife had just welcomed a baby girl to their family and they realized it was the best choice to relocate back to be closer to family. Dr. Lee was a former Junior Olympic swimmer and in his free time, still enjoys swimming. He is also an avid Los Angeles Lakers fan and cheers for his USC Trojans. Aside from patient care, he and his wife are busy raising two wonderful girls: Elise and Kathryn.
