Meet Dr. McCullough

Dr. Tonya Lewis McCullough

Toni McCullough was born and raised in Savannah, Georgia, where she has maintained a successful dermatology practice since 1994. They say that if you love what you do, that you will never work a day in your life. Dr. McCullough truly loves Dermatology; it is not a “job” for her. Dermatology is her passion and her “fun” on a daily basis. She does not just rush in and out of rooms with patients. She truly enjoys giving each patient proper attention and education.


Dr. McCullough and her husband were both born and raised in Savannah. They have two children (a daughter and a son) and a Samoyed. Dr. McCullough was an aerobics instructor for many years, and remains very interested in physical fitness, enjoying running and weight training as well as healthy eating. Dr. McCullough is also an accomplished singer and an award-winning speaker.

Education and Training

Dr. McCullough is a valedictorian graduate of St. Vincent's Academy in Savannah, Georgia. She graduated Summa Cum Laude with a Bachelor of Science in Zoology from the University of Georgia. Her medical degree was obtained from the Medical College of Georgia. Dr. McCullough then completed an internship in Internal Medicine at Memorial Health Medical University Center in Savannah. After her internship, Dr. McCullough began an Ophthalmology residency at Penn State University. However, she realized Dermatology was her true passion, so she returned to the Medical College of Georgia to complete her Dermatology Residency.

Education / Presenter

Dr. McCullough is actively involved in educating others as encouraged by Hippocrates. She educates her patients as well as those in training. Dr. McCullough serves as the Memorial Health University Medical Center Chief of Dermatology. She serves on the clinical faculty for both the Medical College of Georgia (Georgia Regents University) and Mercer University School of Medicine. She participates in the education and training of medical students and residents for these institutions. Realizing that medical education is an ongoing process, Dr. McCullough is continuously reading literature, attending educational conferences, and speaking at conferences to increase her dermatologic knowledge and that of others.
