Dr. Fedderly is amazing! The care that he has given us these last 10.5 years have been top notch! He is kind, compassionate and was so wonderful especially with letting us ask all the questions we needed till we understood. It was meant to be that we had him for our doctor, our son and him have the same heart defect and he really made my son feel at ease with things as he has gotten older, because he could relate from experience. We are so blessed that we had him with us on this journey with our son. It gives me comfort to know that we will transition onto a new doctor that has learned under Dr. Fedderly and he speaks so highly of. I wish that he could stay our doctor forever, but I am so excited for him to enjoy his retirement!
