John B Manna, FNP

I have lived in Lexington, SC since 2005. I received my undergraduate degree from the University of South Carolina and went on to receive my master's degree from the University of South Carolina School of Medicine in Physician Assistant Studies. I enjoy how broad internal medicine can be and I am constantly doing different things on a daily basis. I am challenged and am learning continuously about the most up to date recommendations in medicine. I enjoy reading up on the new recommendations and then educating my patients on these same practices. In my free time, I enjoy weightlifting, running, and reading/listening to books. I also love being outdoors and hanging out with my fiancé, daughter, and golden retriever Cooper.
