A true partner in longevity & lifestyle medicine
You’re already delivering exceptional care. We’re here to help you go further—together.
Why Protocol?
Your patients trust you for proactive, personalized care. But even the most advanced medical care has its limits without structured, evidence-based lifestyle support. That’s where we come in.
Protocol was designed with leading concierge physicians to offer integrated wellness coaching, advanced optional testing, and sustained support—without disrupting your patient relationships or duplicating your efforts.

Protocol began in Boston in partnership with some of the city’s most respected concierge physicians. Building on that success, we are expanding to New York—bringing our integrated approach to wellness and longevity to more patients and providers who demand the highest standard of care.
If you’re a physician in any market, we’d love to explore how we can support your practice and your patients.

Dr. Ajay Haryani trained at the world’s top institutions and bridges worlds that rarely meet. He is a Board-Certified Internal Medicine physician and Assistant Clinical Professor of Medicine at Mount Sinai, with an expert understanding of chronic disease, longevity, fitness, and nutrition.
Unlike most physicians who focus solely on illness, or wellness experts who lack medical training, he brings knowledge of how the body functions in both health and disease – where we thrive and where we falter. He develops personalized care plans that address the full spectrum of health needs, from cardiometabolic health and weight management to emotional health and complex chronic conditions. He is also a Certified Personal Trainer and avid cyclist.
Most recently, he worked with the founder of One Medical (Dr. Tom Lee) to build the cutting-edge primary care company Galileo, supervising doctors and clinical operations across the country. He currently advises leading digital health companies focused on primary care, nutrition and mental health.
