Kimberly Hartzfeld

Prescribing Physician

Dr. Hartzfeld is a board-certified physician with a unique blend of qualifications and nearly two decades of experience helping women regain health.

After earning her medical degree and completing her OB/GYN residency in New York City, Dr. Hartzfeld moved to Arizona. While she loved delivering babies, being on-call evenings led to chronic sleep deprivation. Dr. Hartzfeld decided to pare down and focus exclusively on gynecology. Over the years, she encountered numerous patients with debilitating vulvar disorders and became frustrated that conventional medicine fell short in treating the cause and merely masked symptoms.

Around this time, she started to explore functional medicine to correct imbalances that had been triggered by her lack of sleep over the years. Through her studies, she realized that a personalized, functional medicine approach would also benefit her patients. After seeing this approach transform many lives, Dr. Hartzfeld founded Peak Functional Medicine to help women regain health in a more natural, lasting way. She saw the need to reach more women and turned to Telehealth. Her passion remains centered on restoring hormone health for women in peri-menopause and menopause.

In her free time, Dr. Hartzfeld enjoys hiking, snowboarding and hanging out with her significant other and her two pups Frankie and Bowie.
