Although he has lived in Florida since 1993, Dr. Lacagnina still considers himself a New Yorker. He completed medical training at the New York College of Osteopathic Medicine from 1985 to 1989 and an internal medicine residency program at SUNY Stony Brook. From 1993 to 2010, he practiced general internal medicine. His focus since then has been lifestyle medicine. He is board-certified in lifestyle medicine and also in anti-aging and regenerative medicine. His passion is in the prevention of chronic disease and cancer. He believes most chronic illnesses and many cancers are the result of unhealthy lifestyle choices, and most can be treated, reversed, and even prevented by healthy lifestyle behaviors and choices. Personally, he lives a plant-based lifestyle and exercises 5-6 times per week.
