Dr. Nancy B. Allen

I was inspired to become a rheumatologist during medical school when I witnessed the incredible care and personal bond formed between rheumatologists and their patients. Throughout my residency and fellowship, I trained under a long series of mentors that focused not only on the skills necessary to diagnose and treat rheumatologic conditions but also the importance of understanding the impact of these conditions on patients’ lives. It is an honor to serve patients with all types of rheumatologic conditions, and I am continually inspired by my patients' fortitude and resiliency. On a personal note, my biggest joy in life is spending time with my wonderful wife and three daughters. I am also an avid baseball fan, and I love rooting on the Durham Bulls!.
