Meet Your Endocrinologist
Dr. Alessia Roehnelt, MD
Dr. Alessia Roehnelt, MD, is an endocrinologist board certified in Internal Medicine and in Endocrinology, Diabetes & Metabolism. She brings a deeply personalized, evidence-based approach to hormone, metabolic, and longevity medicine.
Dr. Roehnelt completed her residency in Internal Medicine at The Mount Sinai Hospital in New York City, where she was elected Chief Resident in Medicine. She then completed her fellowship in Endocrinology and Metabolism at the same institution. She practiced at Summit Health for nearly a decade before founding EndoHealth MD in Westfield, NJ. This rigorous training in one of the nation’s top academic centers shaped her integrative approach — combining clinical precision with a genuine understanding of each patient’s individual experience.
"After nearly a decade in a large practice, I saw the same pattern again and again: patients with real symptoms and normal-looking labs, told nothing was wrong. I opened EndoHealth MD to have the time to find out what was." — Dr. Alessia Roehnelt
Dr. Roehnelt is licensed to practice in New Jersey, New York, and Florida, offering both in-person and virtual consultations for patients seeking concierge endocrinology, wellness and metabolic optimization.
