Dr Snyder has treated both of my grown boys. They are now 26 & 27. Treatment was phased. One son only required phase I and the other who needed to go on to phase II. Both had excellent care and results. I had re-treatment, I am a 55 year old "mom" who had original treatment in 1966. Again results were excellent. I am now beginning treatment for our 7 year old adopted daughter from China. She has extreme crowding. She is under evaluation at this time.
