"I think Dr Rivas is the best! I had a good first impression of him that did not change over time. The office staff is very friendly and professional. The aftercare program is also great. Overall I would rate Dr Rivas about a 9 (on a 1 to 10 rating with 10 being the best). His surgical competence and bedside manner both are great. I guess the only negative thing that comes to mind is the phone system in his office. If it was easier to contact his staff I would have to rate him a 10."
