The Minimally Invasive Center of


Westchester and the New York Metro Choice for Minimally Invasive Surgery

Welcome to the Minimally Invasive Center of Hudson Valley Surgical Group. We offer the latest in sophisticated Minimally Invasive Surgical (MIS) techniques with Westchester's top MIS physicians. With a multi-disciplinary approach, our expert surgeons have performed over 18,835 laparoscopic surgeries and provided patients with the latest in Minimally Invasive (MI) surgical care. Built on the combined strengths of prominent board-certified surgeons, the Minimally Invasive Center of Hudson Valley Surgical Group offers a distinctive quality-of-life approach to surgery that results in shorter hospital stays, shorter recovery times and significantly less risk and less pain to patients.

The MI Center of Hudson Valley Surgical Group is patient focused and takes great care to embrace cosmesis as part of their surgical procedures.  We understand that listening to the patient is critical and each patient is an individual that requires a custom solution to meet their exact needs.  The valuable benefit of Hudson Valley Surgeons is that we are extremely well trained in both MI and open surgical procedures. Our primary step in each case is a surgical group consultation that allows us to leverage that experience to develop the best holistic game plan based on all of the patients’ medical complexities.  

MI and robotic surgical procedures are designed to preserve or restore the physical appearance of the patient as part of the surgery.  As surgeons at Hudson Valley Surgical Group, we understand the patients desire to limit scarring and have refined our techniques to provide the best possible cosmetic outcome possible.  Cosmesis and less scarring are part of several benefits including, faster recoveries and less post-surgical complications, that are the result of MI and robotic surgical procedures.  Most surgeries are done on an outpatient basis.
