Shawnie Perkins PA-C

Physician Assistant

Shawnie received her undergraduate degree in psychology from the University of Southern Ca, followed by her Master's degree from Western University of Health Sciences in 2007.  She has practiced in family medicine, urgent care, and pain management, and has additional training in bioidentical hormone replacement and functional medicine.  She lives happily in Chester, South Carolina, with her husband, two children, 4 dogs, 4 cats, and many chickens and rabbits.

​"I have always had a passion for nutrition and holistic living, and a drive to TRULY help people. And by helping people I don’t mean doling out pills; I mean listening, caring, and sharing what I know to help people be empowered and live better lives.  In all of my past positions, I have only been able to do this in short bursts, limited by the money-driven medical industry that requires funneling patients through like a factory assembly line. This did not feel like healing to me, and I always felt a deep dissatisfaction and a certainty that there was something more. My hope is that this clinic will be that something more. For you, for me, for everyone looking for someone to hear you, to support you, and to be your partner in creating true healing."
