National Low T Clinic Careers

Ashley Curl

Ashley Curl started her nursing career in 2012 working at Parkwest Medical Center in the emergency department as a registered nurse.

She continued furthering her education by obtaining a master’s degree at the University of Tennessee, and is now a board certified family nurse practitioner with a special interest in men’s health. Over the last 10 years she has provided exceptional patient care in a variety of settings including working front lines during the COVID-19 global pandemic in urgent care, as well as primary and pediatric care, but she found her passion at National Low T Clinic.

In her spare time she enjoys traveling, reading, learning and wood working. Ashley loves the specialty of HRT, and spends a lot of her time reading, learning, and continuing her education regarding men’s health and HRT to provide the best, evidence based treatment for her patients. “There is nothing more rewarding than seeing the improvement of quality of life for my patients after starting testosterone. We are giving men their lives back, and truly changing their lives for the better. I absolutely love it”.
