Our Team

Through use of the da Vinci® Surgical System, physicians enjoy greater surgical precision, increased range of motion and improved dexterity to perform complex procedures. The computer’s magnified, high-resolution 3D image allows your surgeon to clearly see the actual surgical site – not a virtual image – on a real-time basis, as the da Vinci seamlessly mirrors the movement of his or her hands precisely to perform the surgery.

Your Surgeon is in Control 

Your da Vinci trained surgeon makes every decision based on what is happening at the moment. At no time does the computer have control over the process. Your surgeon sits at a console next to you and operates through the incisions using a camera and tiny instruments.

Every hand movement your surgeon makes is translated by the da Vinci® system in real-time, bending and rotating the instruments so he or she can operate on you. The following surgeons perform da Vinci robotic surgeries at St. Bernardine:
