Dr. Callahan has been treating my Daughter since before she was born (almost 17 years). He is the most caring and conscientious doctor I have ever known. He has gone above and beyond to research more about my daughter's condition and has always been there whenever we needed him. He takes time to listen to us and I always leave his office feeling that he did everything he could. I would highly recommend him!
