Paige Taylor, MS, RN, CPNP-PC

Hello! I’m Paige Taylor. I graduated with my Master’s in Nursing from the University of Arizona in 2016 and worked as a neonatal intensive care nurse for 7 years in several hospitals around the country including Dartmouth Hitchcock Medical Center in New Hampshire and Kaiser Oakland. In 2023 I completed a post-master’s certification as a Primary Care Pediatric Nurse Practitioner at Drexel University in Philadelphia. I trained at several clinics in the East Bay including North Bay Pediatrics. 

After spending many years caring for newborns, I have a special interest in working with new parents and helping them become the best advocate for their child.

I also currently serve as the President for the Bay Area Chapter of the National Association of Pediatric Nurse Practitioners. 

I live in the East Bay with my husband and our dog. In my free time I enjoy hiking, paddle boarding, and traveling.
