The Passion Behind a Solo Physician Practice
Throughout the journey of my career, I have felt fortunate to work within many different practice structures, including multi-disciplinary and specialized group practices both small and large.
Metabolic & Weight Management
Weight changes during perimenopause and menopause are driven by complex biological and hormonal shifts—not a lack of willpower. Backed by advanced clinical training from the Obesity Medicine Association, Dr. McKenzie specializes in targeted metabolic health for midlife women.

Dr Serena Healthcare
With over 30 years of experience in healthcare, Serena McKenzie, ND, IF, MSCP, is a highly specialized solo physician and the founder of Dr. Serena Healthcare. Dr. McKenzie is uniquely distinguished by her four elite subcertifications, which allow her to provide expert, multi-disciplinary care at the intersection of metabolic, hormonal, and sexual health:
• Menopause Management: Nationally certified Menopause Society Certified Practitioner (MSCP) through The Menopause Society.
• Sexual Medicine: Fellow (IF) of the International Society for the Study of Women’s Sexual Health (ISSWSH). She is also a certified sex counselor through the American Association of Sex Educators, Counselors and Therapists (AASECT).
• Obesity Medicine: Recipient of the Certificate of Advanced Education in Obesity Medicine from the Obesity Medicine Association.
A Foundation in Holistic Family Medicine
Dr. McKenzie has been an active force in the healthcare field since 1995. An evidence-based, holistic primary care physician, she earned her doctorate in naturopathic medicine from Bastyr University in 2004 and completed a family medicine residency at the Bastyr Center for Natural Health. In 2006, she founded her private practice, Whole Life Medicine, dedicated to a comprehensive “whole life” approach to evaluation and treatment.
Advanced Metabolic & Hormonal Care
Today, her practice — Dr. Serena Healthcare — serves as a hub for Advanced Metabolic Medicine. Dr. McKenzie specializes in treating primary care complaints with expert attention to sexual concerns, pelvic floor dysfunction, vulvar disease, and healthy aging including weight management. She leverages her trauma-informed and “hormone-aware” methodologies to address complex shifts — such as increased visceral fat and rising cholesterol — that frequently occur during the menopause transition.
A Collaborative, Patient-Centered Approach
By reframing obesity as a chronic biological condition rather than a lifestyle failure, Dr. McKenzie provides her patients with expert guidance on modern pharmacotherapy and nutritional standards to optimize long-term health. Her practice is built on a foundation of integrated care, frequently collaborating with urology and urogynecology specialists to ensure every patient receives the highest level of comprehensive support.




Dr. McKenzie holds a Certificate of Advanced Education in Obesity Medicine from the Obesity Medicine Association, recognizing advanced training in evidence-based, compassionate weight management care for patients at every stage of life.
