Meet Dr. Beth Francis

Dr. Beth Francis

Dr. Francis is a graduate of The Ohio State University College of Dentistry, and her vision is to provide comfortable, compassionate, and comprehensive care to all of her patients. As a proud Buckeye, OSU holds a special place in her heart. In the first four of her eight years she spent there, Dr. Francis earned her undergraduate degree in biology. While in dental school, she served as a student instructor and was an active leader for her peers.

Dr. Francis shares Dr. Armstrong’s passion for organized dentistry and served on OSU’s ASDA (American Student Dental Association) executive board and on the ASDA district cabinet. She is passionate about advocating for the benefit of her patients, and does so through active membership in the American Dental Association and Ohio Dental Association, where she serves on the Subcouncil on New Dentists.

Having been active in clinical research at the James Cancer Hospital and Solove Research Institute, Dr. Francis understands the importance of being a life-long learner. She is constantly furthering her education to provide the best care possible to her patients.

Family is a core principal in Dr. Francis’ personal life. Returning to western Ohio to practice and treat her community as she would her own family was a natural decision. She cherishes the multi-generational aspect of general dentistry, and looks forward to creating healthy smiles in the young and old alike. Her compassionate nature and clinical excellence will put the most anxious patients at ease. Beth and her husband, Trent, welcomed their first child - a girl - to their family in June of 2021.
