I have had Dr. Semel for years and he's a wonderful provider. He's very easy to talk to. He's very understanding. He went into things in depth. He is an excellent, excellent doctor. I found that the nurse practitioner, or no, the MA, she was very courteous. She was very cautious. She did her job well. It's a little bit difficult to understand because she was wearing a mask, but that is nailing on her part. That was just the standard practice, I believe. But that practice is always efficient, always very professional, and always on time. They are an excellent, excellent provider.
