Dr. Samer Othman

Macon Dentist Dr. Samer Othman

Dr. Samer Othman’s Story

Dr. Samer Othman spent his childhood and adolescent years in Macon, Georgia. He graduated from Stratford Academy where he played football, ran track, and was a part of the music theater program.

His father, one of Samer’s heroes and mentors, has practiced internal medicine and nephrology for 35 years at The Medical Center of Georgia and at his private practice. Samer’s mother has been very involved in the community. She worked as a financial advisor for a local bank and was the office manager of his dad’s practice. His mother also played a major role instilling in him a passion for community service.

Dr. Samer Othman decided that he wanted to go into dentistry when he was a senior at Stratford Academy.


“At Stratford, we were required to do a mentorship with a local business, and before then I didn’t know what field I wanted to go into. I chose to do a mentorship with my childhood dentist, and from then on I knew dentistry was exactly what I wanted to do.”

Community Involvement

One of Dr. Othman’s passions is giving back to the community. Growing up in Macon, he truly has a heart for the city and his goal for Advanced Dental Arts is to be a vital part of the community. He has worked hard to develop a restorative dental clinic at the Macon Volunteer Clinic and continues to volunteer there regularly. Dr. Othman also serves on various committees in our community, including the Mercer University Alumni Board, the Georgia Dental Association Executive Committee, Macon Volunteer Clinic Board of Directors, and March of Dimes Executive Leadership Team.

Hobbies & Interest

Dr. Samer Othman enjoys hiking, kayaking, working out, boxing, and spending time with his wife, family and friends in his spare time. He is a huge football fan and his favorite sports teams include Mercer University football, University of Georgia football, and the Atlanta Falcons.
