I would highly recommend Dr. Barton and his associate, Dr. Li, to anyone in need of orthodonitic services in the San Diego area. They successfully corrected the mismatch of my bite. I paid a one-time up-front fee for the procedure and even though my bite correction took considerably more time than originally planned, at no time did Dr. Li skimp on my treatment options or suggest increasing the payment. Both Drs. Barton and Li always fully discussed my options with me and stuck with me until the problem was fully resolved. The entire staff in the office, including the doctors, the dental assistants and the front desk staff, are friendly and concerned, not only about your treatment, but about other issues going on in your life; they remember even small details and ask about them during future appointments. I could not have found a better and more supportive environment to get me through the process.
