      Dr. Sontheimer saved my life. When, I was first diagnosed he was the doctor I talked to, He listened to every symptom, did a very thorough exam and was quick to action. He was such an amazing doctor and I don't think there was a better doctor for the job. He always made an action plan as we would call them and was always a phone call away. I'm so thankful he was here and took care of me over these two years. There is just so many good things to say about him. Phenomenal Doctor!

      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.
