RLM, no second opinion here either. I was referred to the ENT surgeon by the ENT who diagnosed me. I liked the surgeon a lot, checked his credentials, which were superb. He answered all my questions in detail. Explained exactly what he was going to do, drawing pictures to make sure I understood, sent me to be examined by and meet the assisting plastic surgeon, and I never looked back. Post-surgery, before I could even ask for it, he arranged the radiation and chemo. That was four years ago and I am still impressed by him.

If you are comfortable with your choice and he has experience, I agree with Jerry that second guessing is unnecessary. I think you can safely trust your initial impression, given your description of the doc.
