Meet the Team

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”.

Erin is a Texas native but has called Knoxville home since 2019. She obtained a Bachelor of Science in Biology from McNeese State University in Lake Charles, Louisiana, where she also played collegiate volleyball. After deciding to pursue nursing, she obtained a Bachelor of Science in Nursing from University of Texas Medical Branch in Galveston, Texas.

She started her nursing career in 2014, spending the majority of that time caring for patients in the Neurological/Trauma ICU. During this time she also obtained a Master of Science in Nursing from UTMB.

Shortly after, she moved to Knoxville where she worked as a Family Nurse Practitioner for 4 years in a cardiology setting. She then found her passion for Men’s Health at National Low T Clinic.

Erin has a special interest in health and fitness and loves to stay active in her spare time, exploring all the fun activities that East Tennessee has to offer. She also loves to read, listen to Taylor Swift, play with her dog, and attempt (mostly successful) DIY projects. Erin loves to witness the positive effect that hormone replacement therapy has on her patients and loves being able to make a difference in her patients lives.

Emily is a Family Nurse Practitioner who graduated from Lincoln Memorial University in 2015 with her Bachelor’s of Science in Nursing and then continued her education by obtaining her Master’s of Science in Nursing from LMU as well.

Emily’s nursing background spans several different medical settings, including inpatient cardiology, nursing education, hospice care, veteran’s disability, and primary care.

Outside of the office, Emily enjoys cooking, browsing through antique and thrift shops, and playing guitar and singing. Emily’s favorite part of working in hormone replacement therapy is seeing patients’ energy levels and overall quality of life improve with balanced hormone levels.

Kristen Endzel, FNP-BC, is a board-certified Nurse Practitioner specializing in hormone replacement therapy with a strong passion for whole-person wellness. With a holistic, patient-centered approach, Kristen helps individuals restore hormonal balance and reclaim their vitality through personalized, evidence-based care.

Recognizing that hormones influence every aspect of physical, mental, and emotional health, Kristen takes time to understand the full picture—lifestyle, nutrition, stress, sleep, and beyond—when crafting treatment plans. She integrates advanced diagnostic tools with bioidentical hormone therapy and wellness strategies to support optimal aging and long-term well-being.

Kristen works closely with both women and men experiencing hormonal imbalances related to menopause, andropause, thyroid dysfunction, adrenal fatigue, and more. With a compassionate, empowering style, she partners with patients to help them feel their best at every stage of life.

Outside of clinical practice, Kristen enjoys yoga, hiking, and cycling, believing that true wellness starts with living in alignment with your values—body, mind, and spirit.

As a dedicated Nurse Practitioner, I am passionate about identifying and treating the root causes of illnesses to enhance the quality of life for my patients. I believe that effective healthcare goes beyond simply treating symptoms; I focus on holistic approaches that empower individuals to achieve optimal health.

I earned my Masters and Bachelors of Science in Nursing from Lincoln Memorial University. Throughout my career in healthcare, I have discovered my passion lies in proactive medicine rather than reactive care. I take pride in creating a safe space where patients can openly discuss their concerns and goals, striving to ensure they always feel heard and cared for.

I am committed to contributing to the health and wellness of our community. My goal is to inspire hope and resilience in my patients, guiding them toward healthier, happier lives. I look forward to partnering with you on your journey to optimal health!
