Robert J. O'Donnell, DDS

Dr. O'Donnell has provided comprehensive dental care for generations of families in the Atlanta area for over 30 years.

After receiving an undergraduate degree in Microbiology from The University of Georgia, he completed his Doctor of Dental Surgery in 1986 from Emory University. He served five years as Clinical Instructor for Emory's Department of General Practice Residency for Post Graduate Dentistry and opened his own practice in 1989.

Dr. O'Donnell embraces ongoing training for himself and his staff, and he promotes a patient-focused commitment to optimal oral health care, for all ages. A strong believer in community service, he stays very active in a number of professional associations and volunteer organizations.

When not practicing dentistry, Dr. O'Donnell enjoys time with his family at their home in Milton. Traveling and golf are some favorite pastimes, and it's not uncommon to find him coaching a soccer game or two on the weekends.

Dr. O'Donnell has been married to his wife Cheryl since 1996, and they are active members of St. Thomas Aquinas Catholic Church. They are the proud parents of two daughters, Kathleen Elisabeth and Ryan Kerry.

The thing I like most about being a dentist is the relationship that I have with my patients… I've had patients that brought their children, and now their children are grown and married and are bringing their children… The relationships that we build with those families is what's most important to me.”

Dr. Robert J. O'Donnell
