ADVANCED EDUCATION IN GENERAL DENTISTRY

Susannah Payne, D.D.S. Class of 2015
Advanced Education in General Dentistry Certificate 2019
Associate Clinical Professor, Department of Comprehensive Dentistry
School of Dentistry, UT Health San Antonio
Co-Owner, Payne Dentistry, San Antonio, Texas

“Dentistry all started for me Christmas Eve of 2009. My father, Dr. Steven Payne (D.D.S. Class of 1978), received a phone call from a patient who had lost a front tooth out of his partial denture and was embarrassed to attend his family gathering the following day. I offered to accompany my father so he wasn’t by himself and ended up being allured by this world of science, art, and community care. I matriculated two years later and had ideations of attending a specialty program in periodontics. Dr. Ed Wright had an enlightening conversation with me in the hallway telling me how crazy I would be not to join into practice with my father, whom he had taught with in the Dental Anatomy class for decades. This was the moment I first learned of the Advanced Education in General Dentistry program where a general dentist could be taught by specialists and trained to perform procedures in all specialties. My interest in this program continued to be nurtured by Dr. William Rose who has literally created a dynasty of residents.

A blip on the radar of my dental career was a move to Seattle, Washington, to practice for two years. A key aspect of this move was learning the business side of dentistry from two different offices in the region, one corporate and one private. I encourage all newcomers to pursue such an experience to gain wisdom from successful businesses. This allows you to incorporate them into your permanent clinic home. My plan was always to return to complete our AEGD program, and I was fortunate to be accepted into the program under the direction of Dr. Luis Yepes. I opted to undergo two years of training and was blown away at the amount I learned during that time. My method of practice before and after completing the program is astounding. This encompassing knowledge allows me to formulate the best plans for my patients and gives me the skillset to accomplish most of it myself. When unable to complete procedures myself, I can explain to my patients in much greater detail and with confidence what they will need; this results in their following through with referrals on a more frequent basis.

The most fun part of my dental life by far has been the last year I have been practicing with Dr. “Big” Payne and getting to return to the AEGD program as an attending part-time faculty member. Teaching in arguably the strongest AEGD residency in the country I am continuously proud of the progress in practice our residents obtain and how eager they are to prove their abilities. Our curriculum and talent as far as mentors within the program improve every year and I am lucky to consider myself a small part of their incredibly talented team of teachers currently led by Dr. Ahmed Sabbah, part of the GPG3 Dynasty.”
