About Our Company - MD Total Wellness

Why Wellness?

Our healthcare system overlooks wellness, focusing instead on the diagnosis and treatment of disease. Not us! Our mission is to optimize your wellness, so you can feel better, live better, and be better!

Allison Mollet, PA-C

Physician Associate

Allison Mollet is a board-certified physician associate, in clinical practice since 2002, and specializing in weight loss and hormone replacement for men and women. She started her career in metabolic and weight loss surgery and was drawn to the medical weight loss, wellness, and anti-aging field after recognizing how often serious symptoms of perimenopause, menopause, and testosterone deficiency are overlooked, trivialized, or mistreated. Too often, men and women go decades with significant (and sometime debilitating) symptoms that can be effectively addressed with natural bioidentical hormone replacement. Patients are often unaware of the increased health risks that accompany hormone deficiencies. PA Mollet provides attentive and compassionate care and develops personalized treatment plans based on each patient’s unique needs. She prioritizes wellness and preventative care to help patients reclaim their quality of life.

PA Mollet graduated from Yale University School of Medicine PA Program where she also obtained her Master of Medical Science degree. She earned her bachelor’s degree in exercise science and physical therapy with a minor in Biology from Western Washington University. PA Mollet served as founding faculty and Program Director for the Marshall B. Ketchum School of PA Studies, the first PA program in Orange County, and continues to lecture and teach on specific medical topics.

She is a member of the American Academy of PAs (AAPA), the California Academy PAs (CAPA), and the American Academy of Anti-Aging Medicine (A4M).
