Dr. Parikh is simply the best. Without going into too much personal detail, he was our light at the end of a very dark tunnel. He and his staff were always so patient, positive, and accommodating. A situation that at one point seemed incredibly grim and confusing was broken down into individual steps by this skilled doctor and his staff that led to a much more positive road. The wait times are minimal when you have an appointment, and the doctor will never make you feel rushed or leave without answering all of your questions. He truly cares about each of his patients, and that is a rarity in this city. Switching to Dr. Parikh was probably one of the best decisions we've made. I have referred a friend to see him when he also was faced with a tough situation. He cannot thank me enough for referring him to a Dr. who for once not only knew what he was talking about, but was patient and compassionate enough to help get his patients through a very difficult and confusing time in their life.
