      Recently took our 6 year old daughter for an appointment, what a wonderful Doctor. Been thorough, caring, and took the time to get to know her and her issues. Very understanding of my concerns, and explained everything in good detail. Would highly recommend him! Thanks for everything!

      My son and I both liked Dr. Sontheimer very much. The first thing he did when he walked in the room was finish playing our game of hangman with us, which was great! He listened while I said everything I wanted about my son's symptoms. He was gentle and thorough on his physical exam. I loved the treatment plan he placed in motion. His communication and follow up were all top notch.
