Dr. Charmeka Lipscomb, APRN, FNP-C, PMHNP-BC currently works as a mental health provider for Prism Health North Texas. She obtained her BSN degree from the University of Texas at Arlington. After a few years of floor nursing, she thought she wanted to take on management so she obtained a dual master’s in business administration and healthcare administration from Texas Women’s University. While working as an associate unit manager for Parkland’s HIV outpatient services, Charmeka found her first true passion and it wasn’t management; it was HIV. This passion prompted her to return to Texas Women’s University to obtain a Master’s of Science degree to become a Family Nurse Practitioner. Her first job upon completing nurse practitioner school was with Metrocare Services. It was there that Charmeka discovered her second love, mental health, which prompted her to get her post-masters certification in mental health from the University of Texas-Rio Grande Valley. She received her doctorate from Chatham University. Prior to PHNTX, Charmeka was the lead HIV provider for Parkland’s HIV jail services for over 5 years. HIV and Mental Health are passions of Charmeka’s because they are two of the most stigmatized disease processes in the black community. Until they’re openly discussed, the numbers will continue to grow and people will continue to suffer in silence. So let’s talk about it!

“I hope that people feel like themselves when they are around me and feel safe to be themselves when they are around me, and maybe that makes people think it’s me that they love but really its real themselves that they love.” –Tracee Ellis Ross
