Our Surgeons

There are many things to consider when you are choosing a colorectal surgeon.

But most of those considerations can be boiled down to just one question: does my surgeon treat this disorder often?

The surgeons in our division see a wide variety of colorectal conditions—from the simple to the serious—every day. As a result, we have a greater depth of experience than most colorectal surgeons, especially in handling complex or difficult cases.
