It was incredibly difficult picking a provider from the huge list of providers available, so when we picked Dr. Muthu, we were not disappointed after our first visit. He was very helpful, charming, and had me feeling really awesome about everything. I definitely will be recommending him. The office staff, however, can be hit or miss. So far my wife and I have had only good experiences with the staff but I have heard of mixed feelings.
