About
Dr. Erfanul Saker is a board-certified Internal Medicine physician and Diplomate of the American Board of Obesity Medicine. He completed both his medical education and Internal Medicine residency at the Icahn School of Medicine at Mount Sinai - Elmhurst Hospital. The Gold Humanism Honor Society recognized him for clinical excellence and compassionate, patient-centered care.
Before founding Saker Concierge Clinic, Dr. Saker practiced as a traveling physician across hospitals and healthcare systems throughout the United States, including rural communities. That experience gave him an unusually broad view of how patients navigate complex, fragmented care. He is deeply passionate about preventive cardiology, cardiovascular risk reduction, metabolic health, and obesity medicine. His clinical interests reflect his personal history as well. Of South Asian descent with a strong family history of cardiovascular disease, he took his own elevated LDL cholesterol seriously. Through targeted changes to nutrition and exercise, he reduced his LDL from 134 to 108 mg/dL and raised his HDL from 40 to 58 mg/dL, choosing lifestyle intervention before medication. He lifts weights four to five times per week and maintains an active lifestyle. That lived experience shapes how he counsels patients on prevention and long-term health. His guiding belief: information is everywhere, but understanding is not.
