Melissa R Grinnell, PA-C

Gastroenterology

Meet Melissa

I enjoy helping patients achieve optimal digestive health through compassionate, comprehensive, collaborative care. I work with patients to understand their history and concerns while helping to establish a plan for improved health and wellness. I have been practicing since 2012 and joined Bon Secours in 2023. Outside of medicine, I enjoy spending time with my husband and two children, reading, playing pickleball, traveling, and eating good food.
