Meet the Team
Peter Miller
Co-Founder, CEO
Peter Miller’s journey into longevity and health optimization began with a personal wake-up call—a surprise diagnosis of severe type-2 diabetes. Unwilling to accept a future of declining health, he took control, reversing the disease through a complete lifestyle transformation. By losing 65 pounds, embracing cutting-edge science, and rethinking everything he knew about health, Peter discovered firsthand the power of proactive, preventative medicine. With a background in guiding some of the world’s largest companies through transformation, Peter brings a fresh perspective to the healthcare space. He saw an industry focused on managing sickness rather than optimizing health—and he knew it could be different. That vision led to Longitude Health, a clinic built on the idea that longevity isn’t just about living longer, but living better. Under his leadership, Longitude Health is redefining what’s possible, helping people take control of aging, vitality, and long-term wellness.
