At Grossman Wellness Center, every patient receives a white-glove experience. Our physicians dedicate the time and attention needed to understand your goals, review your results in depth, and guide every decision. We have spent more than two decades helping patients from across the country and around the world extend both the length and quality of their lives, with locations in Denver, Colorado, and Snowmass, Aspen, Colorado.
Our foundation was built on the pioneering work of Terry Grossman, MD, a physician who challenged conventional medicine, championed evidence-based longevity care, and embraced the transformative power of emerging technologies. Today, that vision remains the heart of who we are.
Our model of longevity medicine is rooted in three core principles: evidence-based care grounded in comprehensive testing, science, and measurable outcomes; a fully personalized, high-touch experience defined by protected, unrushed physician time and highly personalized guidance; and forward-thinking innovation, using leading-edge tools and technologies that are rigorously tracked to ensure meaningful benefit. This is longevity care as it was meant to be: precise, thoughtful, and built around you.
Care is delivered through physician-led programs designed around each patient’s goals, including the Stay Alive ForEver (SAFE™) Program for proactive longevity and disease prevention, the Program for Elite Performance (PEP) for performance optimization of body and mind, and the Hormone, Metabolic, and Cardiovascular Health Optimization Program, along with a range of additional therapies and evaluations available to further personalize each patient’s care.
For 25 years, patients have trusted our team because of Terry’s philosophy: generous physician time, personalized care, and science-forward guidance designed to meaningfully enhance healthspan. As we grow the clinic, that original vision remains alive and central to every patient we serve.

Dr. Terry Grossman is our clinic’s medical director. He has been in the active practice of clinical medicine involved in direct patient care for 46 years. Dr. Grossman is a leading medical authority in the field of anti-aging medicine and preventive medicine. His particular fields of interest include longevity medicine, executive wellness, regenerative medicine, and therapeutic plasma exchange (TPE).
He graduated from Brandeis University in 1968 and the University of Florida School of Medicine in 1979. He spent his first 15 years of his medical practice working as a community family doctor in the Colorado mountains, practicing in a small community where he delivered more than 700 babies and ran an emergency medical center. From 2013 to 2020, Dr. Grossman served as the International Medical Director at Vitallife, the wellness division of Bumrungrad Hospital, one of the world’s leading hospitals located in Bangkok, Thailand.
He is a member and board-certified by the American Academy of Anti-Aging Medicine (A4M), the American Academy of Ozonotherapy (AAOT), and the American College for Advancement in Medicine (ACAM). He has published four books on longevity medicine, most recently (2025), Plasma Reset: Change Your Blood, Change Your Life written with another of our clinic’s physicians, Dr. John Kelley.

Dr. John Kelley is a regenerative medicine specialist dedicated to extending health span and enhancing both quality of life and longevity for his patients. He is co-author of the book Plasma Reset: Change Your Blood, Change Your Life (italics) with Dr. Terry Grossman, and is recognized as an expert in therapeutic plasma exchange, an innovative therapy that removes and replaces blood plasma to reduce inflammation, clear toxins, and support optimal aging.Dr. Kelley has completed advanced training and certifications in longevity medicine, integrative medicine, functional medicine, and ultrasound-guided stem cell injections.
At Grossman Wellness Center, he delivers highly personalized regenerative and anti-aging programs tailored to each patient’s needs. His early career in primary care exposed him to the limitations of the conventional “sick care” model, prompting him to shift his focus toward identifying and treating the root causes of disease. This path led him to direct the Brain Health Program at the Texas Center for Lifestyle Medicine and later join Grossman Wellness Center. He is a co-founder of the Physician Transformation Institute and a member of the Clinical Peptide Society.
Dr. Kelley earned his medical degree from the Medical College of Georgia and completed his residency in Family Medicine at St. Anthony’s in Denver, CO.

Dr. Sam Grossman, M.D., J.D. is the son of longevity pioneer Dr. Terry Grossman. He completed post-graduate training in emergency medicine at Duke University and now works at Grossman Wellness while continuing to practice in the ER.
At Grossman Wellness, he focuses on helping patients understand their risks, make sound long-term decisions, and thoughtfully integrate longevity and performance tools into everyday life. As an avid runner and certified endurance coach, he brings a deep personal understanding of training theory and the crucial role of aerobic fitness in healthy aging. His legal training sharpened his attention to detail, communication, and informed consent, and he brings that same clarity to shared medical decision-making.
Time in the emergency department caring for acutely ill patients shaped his sense of what truly matters for prevention and long-term health. He approaches care as a partnership: honest conversations, clear plans, and aligning medical decisions with each patient’s goals and values. Outside of work, he’s happiest with his kids and family, on a powder day, or exploring new places.

Dr. Michael FitzGerald is a board-certified emergency physician who completed his emergency medicine residency at Duke University Hospital and now works at Grossman Wellness while continuing to take ER shifts in Colorado. At Grossman Wellness, he focuses on building clear, data-driven plans around strength, cardiovascular risk, metabolic health, and long-term performance.
As a former college athlete with a bachelor’s degree in nutrition and food science and TPI certified, he has a breadth of experience designing training and nutrition plans for high-level athletes, which shapes his approach to longevity-centric care. Time in the emergency department caring for patients at critical moments reinforced his belief that waiting for disease to declare itself to treat, while necessary, is the wrong place to start. He approaches care like coaching: set specific goals, measure what matters, collaborate and adjust the plan as life and circumstances change.
Outside of work, he loves racquet sports, the ongoing puzzle of golf, and spending time in the mountains with family and friends.
