Professional Background

Didier Guillaume, D.M.D., often referred to as Dr. G by his patients, is a true smile designer.  Guillaume's specialties include complex, high-restorative, cosmetic, and implant dentistry.  

Dr. G received his dental degree from the University of Medicine and Dentistry of New Jersey in 1999, and then attended the School of Biomedical Sciences for a year before attaining his certificate in Prosthodontics from the University of Medicine and Dentistry of New Jersey in 2002.

While attaining his certificate in prosthodontics and implant dentistry, Guillaume completed clinical research on the revolutionary implant techniques for the Biohex Implant Company.  He presented projects at the International Academy of Dental Research in Washington, DC and at the American College of Prosthodontists meeting.  In addition, he has lectured at the Northeast Implant Symposium and for continuing education seminars for general dentists.  

While in his residency, Dr. G was admitted to the Gamma Pi Delta Prosthodontic Honors Society and also became a member of the American College of Prosthodontists. 

When relocating to Atlanta in 2002, Dr. Guillaume was hired as one of the head Prosthodontists for a 17 practice dental group, and then worked for a 3 practice dental group while being part-owner of a private practice in the Atlanta area.

He has since ventured out on his own and created Astoria Dentistry, LLC where he takes great pride in the science and artistry that goes into every bright smile.
