Dr. Drew Moss

Medical Director & Co-Founder

Drew is the Co-Founder and Medical Director of Peak Lifestyle Medicine, where he leads the clinical vision, medical care, and development of personalized health and wellness programs.

As a physician with a background in primary care, Drew has seen firsthand the value of looking beyond isolated symptoms and taking a more proactive, comprehensive approach to health. He is passionate about helping patients better understand what is happening within their bodies and using that insight to make thoughtful, informed decisions about their care.

His approach focuses on helping patients improve how they feel and function today while also considering the bigger picture of long-term health, performance, and healthy aging. Rather than relying on one-size-fits-all solutions, Drew works with each patient to develop an individualized plan based on their goals, lifestyle, health history, and clinical needs.

At Peak, Drew oversees each patient’s medical care while working closely with Elizabeth to create an experience that connects clinical treatment with practical nutrition and lifestyle support. His goal is to make proactive healthcare feel approachable and sustainable, giving patients the guidance, tools, and ongoing support they need to take a more intentional role in their health.

As Medical Director, Drew also guides the continued development of Peak’s clinical programs and standards of care, ensuring the practice remains grounded in thoughtful medicine, personalized attention, and a commitment to helping patients feel, function, and live at their best.
