Katie Stein RN, MSN, CPNP-PC

Katie, a native of Washington, D.C., spent several years in the Boston area while pursuing her Nurse Practitioner degree at Boston College and immersing herself in the vibrant city life. However, in 2019, she made the decision to return to her hometown.
After coming back to the District, Katie worked at Children’s National Hospital and gained valuable experience at another private practice. Eventually, she became a valued member of the team at West End Pediatrics.
During her leisure time, Katie cherishes moments with her loved ones and close friends. Exploring new culinary experiences by visiting various restaurants is one of her favorite pastimes. She also finds solace in lap swimming and enjoys spending time outdoors, embracing the beauty of nature.
