clear and precise explanation

Both of my procedures went well. I walked in thinking it was a simple consultation, and ended up being prepped for surgery a couple hours later. I was very nervous. Both procedures went smoothly, and the problem was fixed. Both surgeons made me feel safe and explained the procedure to make sure I understood what would happen.

I was very happy with the doctor and looking forward to having the surgery. Thank you.

I had a great experience with my biopsy with the whole team. They were kind and explained everything. They were thorough and pain was minimal. It's very, very, very nice. Checked in with me. I would highly recommend this team to anyone, and I would like to thank them very much.
