Eric Nager, M.D., is a dedicated practitioner in the fields of Anti-Aging, Functional, and Regenerative Medicine. Originally from Brooklyn, New York, Dr. Nager pursued his passion for medicine at New York University, majoring in psychology while minoring in biology and chemistry. His academic journey continued at the State University of New York in Brooklyn, where he graduated Cum Laude and subsequently completed a residency in Emergency Medicine at the Medical Center of Delaware.

His extensive career in public service included roles such as Medical Manager for the Pennsylvania Urban Search and Rescue Team, Fire Surgeon for the Baltimore County Fire Department, and Tactical Physician for the Harford County Sheriff’s Office. Over time, Dr. Nager recognized the limitations of a reactive approach to medicine that merely addressed symptoms. This realization fueled his pursuit of a more proactive, holistic approach. He delved into research, exploring avenues like lifestyle changes, nutrition, supplements, hormones, IV therapy, and Regenerative Medicine.

His exploration led him to embrace Functional Medicine, a partnership-oriented practice grounded in evidence. Dr. Nager’s commitment to enhancing his skills led him to the American Academy of Anti-Aging Medicine’s fellowship program. Today, he is a Board-Certified specialist in Anti-Aging, Functional, and Regenerative Medicine.

“Dr. Nager is wonderfully experienced, skillful and informed. His knowledge of the broad and modern field of medicine which he now practices is expansive. He has helped me for a variety of ailments, such as arthritis, aging, reflux, dairy intolerance and a few others, with the angle to attack the cause of the problem and let’s find a remedy, not just treat the symptoms. I’ve had excellent results with his treatments. Sometimes its a trial and error as different treatments work differently for different people. Do not let that deter you. I have 100% confidence in him and this tremendous newer filed of medicine known as integrative, functional and restorative.”
