Review of Dr. Fedder

- |

Dr. Fedder was very thorough in explaining my husband's procedure to us. He has a great bedside manner and explained things in layman's terms. Would definitely recommend him.

Review of Dr. Fedder

- in Belleville, IL |

Dr Fedder was amazing! Very patient and explained everything that would happen before going into surgery. Unfortunately his office staff is not very helpful. When specifically asked if they took my insurance, I was informed absolutely and everything would be billed. When everything was said and some I was informed they had no way of billing the insurance and I was left holding the bag. While I appreciated Dr Fedder, this knowledge would have significantly impacted my choice to use their office

Dr Fedder has been my gastroenterologist since 2005 when he found a suspicious lesion. He is such a kind and considerate doctor. He explains all and puts me at ease. I highly recommend him.

Review of Dr. Fedder

- in Edwardsville, IL |

Dr Fedder was very informative about my husband's procedure. He saw him before and after and explained everything to both of us. Even though he had many procedures that day he did not seemed rushed and his bedside manner was the best my husband has experienced. I will definitely see him when I have to have my ten year colonoscopy.
