I went to Dr Osorio's ofc for several years while working in Boston. His entire staff are professional and knowledgeable. Any insurance issues, they helped resolve. I had several crowns & 2 front teeth caps done. The front caps took longer than I would have liked but the end result was well worth it. No one has ever guessed they are caps. I would highly recommend him and his office. I just stopped working in Boston and am struggling to find someone as good.
