“The first thing we do when we first meet is listen. We try to understand. We try to understand what symptoms a person is having….Then after listening and doing a comprehensive examination, we talk at length about the diagnosis, what we expect to do in the staging workup…and then based on the testing results, we come up with possible treatment options.”
