Glenda M. Jeffries, FNP


Glenda was born in Savannah, Georgia but her family relocated to her mother’s home state of North Carolina when she was a young child. She attended the University of North Carolina, Chapel Hill and obtained her BS in nursing in 1987. Glenda became certified as a nurse practitioner in 2010 upon graduating from UNC with a Master's degree in nursing. She has enjoyed working as an RN for 23 years and helped to found North Raleigh Family Medicine in 2000. She has worked here as a nurse, office manager, bookkeeper, and phlebotomist. During a medical mission trip to Bolivia in 2008 she became inspired to do more than just "triage patients." She wanted to learn how to diagnose and treat their ailments. Hence she enrolled in the UNC's graduate school.

We are glad to have Glenda's help and guidance. She lives in North Raleigh with her husband - Dr Jeffries, and enjoys being a mother and Grandmother. In the past 10 years, Glenda has been on medical mission trips to Bolivia, Belize, Haiti, and the DR of Congo.
