Dr. Lisa Gao, DDS, MS and Dr. Mark A. Collons, DDS

Our board-certified orthodontists have expertise in the latest and most effective orthodontic treatments. Only a small percentage of orthodontists are board certified which requires completion of a rigorous peer examination process by the American Board of Orthodontics.

Dr. Gao earned her Doctorate degree in Dentistry from the University of California at San Francisco. She completed her orthodontic residency at Ohio State University where she also earned a Master of Science degree. Dr. Gao is also a Diplomat of the American Board of Orthodontics. When Dr. Gao is not in the office transforming smiles, she enjoys spending time with her family and dog Teddy.

Dr. Collons is a Trojan Alumni and attended University of Southern California for both dental school and orthodontic residency. Dr. Collons is a native of Santa Monica and is an active member of the community. He also enjoys spending time with his grandchildren.
