Dr Menendez was born in Miami, Florida. He attended the University of Florida and Florida International University, before moving abroad to Prague, Czech Republic and attending medical school at Charles University in Prague, one of Europe's oldest medical schools. He returned to the states and continued his training at Atlanticare Regional Medical Center, where he was Chief Resident of the Internal Medicine Program.
He has primarily worked as an internal medicine hospitalist, first in acute care medicine, and more recently, in post-acute rehabilitation medicine. His transition to Hormone Replacement and Anti-Aging Vitality medicine came about through a personal interest in wellness, and a desire to establish a meaningful and impactful doctor-patient relationship which was missing in his hospital based practice.
