Our Specialists

The board-certified surgeons of CMU Health Department of Surgery are dedicated to giving you the best care possible. We believe no procedure is routine. 

Each surgery – your surgery – requires the utmost attention and precision.

That's why we are constantly educating ourselves about our specialties and the advances within them. Your care is our priority.
