Dr Monsour and his team are exceptional. The patient experience in terms of attention to detail, courtesy and communication are excellent. Dr Monsour is perhaps one of the best doctors I have interacted with. His disposition, knowledge and experience based confidence are a calming influence in the midst of challenging circumstances. Is really anything more you want from a Dr? I don't think so. This is exactly what you want and need.
