Transformative Longevity Medicine, Personalized for You

Root-cause medicine. Groundbreaking science. Compassionate care.
our physicians

Welcome to a new era of aging well. At our clinic, we don’t just manage symptoms—we uncover and address the root causes of illness to optimize your long-term health. Whether you’re navigating complex, chronic health conditions or simply looking to extend your healthspan, our expert-led care, cutting-edge diagnostics, and proven functional medicine approach help you lower your biological age, increase vitality, and live a longer, healthier life.

Our clinic is the birthplace of the Younger You Method. The Younger You method is a proven diet and lifestyle approach that targets DNA methylation through simple daily habits—like eating epinutrient-rich foods, getting quality sleep, moving moderately, and managing stress. Clinical trials showed remarkable results: participants who followed the Younger You Method lowered their epigenetic age by up to 4.6 years, with one study showing a 3.23-year reversal in just 8 weeks.

Dr. Kara Fitzgerald

Powerful, science-backed aging reversal—made practical.

“In most conventional clinics, doctors focus on suppressing symptoms rather than addressing the underlying causes. Our approach is different — we use a systems-based model to restore health at its core, identifying and correcting imbalances rather than masking them.” – Dr. Kara Fitzgerald
