Meet Dr. DiGiovanni


fish_appt.pngI feel very fortunate to have had the opportunity to provide orthodontic care to so many fantastic families in the Orange County Community over the past 20 years. As your orthodontist, my goal has always been to make each patient’s experience in our office as enjoyable as possible by providing the highest quality, state-of-the-art care in a fun, friendly and nurturing environment.

It is my practice philosophy that outstanding patient care can only be achieved when there is excellent communication. This involves discussing treatment progress with you personally at each visit so you will always know how your treatment is progressing as well as coordinating your treatment with your dentist and dental team. In our office, we encourage open communication as much as we do quality service and care.

We pledge to provide you a truly positive experience based on one-to-one personal care and the finest orthodontics available anywhere. A warm welcome to our orthodontic family and practice!
– Dr. John DiGiovanni

    Angle Certification

    The Edward H. Angle Society of Orthodontists (EHASO)

    In addition to being a Board-Certified Diplomate, Dr. DiGiovanni is one of a select group of orthodontists with the distinction of being a member of the prestigious Edward H. Angle Society.

    Only a select few orthodontists are chosen worldwide to become a candidate after displaying a high level of academic and clinical excellence as well as being a positive contributor to the profession. To achieve full membership, chosen orthodontists must complete and present clinical case reports and a written report in a format suitable for publication. Members must then continue to display competence to maintain their membership.

    Membership into the Angle Society is by invitation only. Today, the Angle Society has only approximately 660 members worldwide, of which approximately five percent of orthodontists in the United States are members.
