Dr. Joseph Merritt grew up and currently resides in Roswell, Ga., and he is a proud alumnus of Roswell High School. After graduating from the University of Georgia with a Bachelor of Science in Biology, he obtained his Doctor of Dental Medicine (DMD) degree from the University of Louisville, School of Dentistry.

The driving force of Dr. Merritt’s career is his calling to serve others locally and in communities with limited access to dental care. He has volunteered on multiple dental mission trips to Nicaragua and Jamaica. Dr. Merritt also volunteered at a Free Day of Dentistry several years in a row in Savannah, Ga., where he started his career in dentistry.

Dr. Merritt specializes in restorative and cosmetic dental procedures. He is also a certified Invisalign® provider. As a commitment to his patients and his profession, Dr. Merritt is dedicated to consistently immersing himself in continued education. He has accumulated hundreds of hours of CE (and counting) by being an active member of a Spear Study Club, regularly attending the Thomas P. Hinman Dental Society Meeting, and pursuing specialized courses to expand his skillset.

Outside of the office, Dr. Merritt enjoys staying active, traveling, spending quality time with family and friends, and rooting for the Georgia Bulldogs and Atlanta matter how heartbreaking that may be!
