About
At Modern Medical Concierge in Purchase, NY, three physicians deliver primary care, functional medicine, and a wide range of specialty wellness services. Dr. Jan Zislis founded the practice in 2011 under the name Country Doc Concierge. The practice evolved into Modern Medical Concierge with a philosophy rooted in whole-person care. Every new relationship starts with a conversation, not an exam.
The team treats both acute and chronic conditions across lower Westchester and Fairfield counties. Dr. Melissa Gennarelli brings board-certified internal medicine expertise with a focus on prevention and chronic disease. Dr. Michael Canter co-leads the practice's elder care and palliative care program. Beyond primary care, the practice offers bio-identical hormone pellet therapy, IV infusion therapy, OMNIWave shockwave therapy, GAINSWave and FemiWave sexual wellness treatments, and facial aesthetics. The practice keeps its membership small to ensure each patient receives thorough, personalized attention.
