California Age Management Institute is the Monterey Peninsula's leading anti-aging and functional medicine practice, founded in 1996 by Dr. Philip Lee Miller — a pioneer in the field and one of the longest-practicing anti-aging physicians in the country. Formerly known as Los Gatos Longevity Institute, it was the first full-service, physician-directed anti-aging medicine center established in the United States. Dr. Miller's approach is rooted in a conviction that aging should not mean accepting the progressive loss of energy, hormonal balance, cognitive sharpness, and physical capacity — and that functional medicine offers a proven path to reversing that trajectory. For nearly three decades, the practice has helped thousands of men and women reclaim their vitality and live with optimal health at every age.

About the Physician

Dr. Philip Lee Miller, MD is the founder of California Age Management Institute and the author of The Life Extension Revolution — a foundational text in anti-aging medicine. With nearly 30 years of experience in functional and anti-aging medicine, Dr. Miller has helped thousands of patients address the root causes of hormonal decline, metabolic dysfunction, cardiovascular risk, thyroid imbalance, and cognitive slowing. His practice philosophy rejects the conventional medicine model of 15-minute symptom management in favor of comprehensive health blueprinting — total-person diagnostics, extensive lab analysis, and individualized protocols targeting what is actually driving a patient's decline. Dr. Miller has been at the forefront of bioidentical hormone therapy, micronutrient optimization, and longevity medicine since before these terms entered mainstream medical practice.
