    I have no recommendation. The doctor was excellent from surgery up through post-op appointment. His assistants, fellow doctors that were involved, all courteous and professional. I've been really happy with the outcome of the surgery and the doctor was super, super personable. And that's it. Just wanted to share that I was really happy with the doctor.

    I have enjoyed my visits to this office. Very little wait time and everyone is super nice and seems to know their job responsibility. If I had to critic anything it would be to make a note on the patient's chart about what sport they play, it would go a long way with the parent that the doctor remembered it. But I know he sees tons and tons of patients
