Carolyn Barnes, MD

“I chose to be an oncologist because I believe the worst fight is worth fighting for. Making sure my patients are getting the best possible care is what gets me out of bed every day. I always look forward to seeing my patients for cancer-free follow ups.”

Dr. Barnes is married and has three children. She enjoys hiking, swimming, playing the piano and spending time with her family.
