Dr. Fesenmyer was insanely unprofessional and treated my dad as if he were an inconvenience. Despite having a scheduled appointment, the doctor was confused as to why my dad was even there. He treated my parents like an annoyance and showed zero bedside manner. It is sad to see that so many other reviews reflect the exact same experience my family had. How can someone be so highly educated yet so rude and unpleasant? You really need to check your attitude, Dr. Fesenmyer.

I had an appointment with Dr. Fesselmeyer, and unfortunately, I didn’t feel like my condition was taken seriously. I live with this illness daily, but I felt rushed through the process, and it seemed like my concerns were brushed aside in favor of quick prescriptions. I also felt his bedside manner wasn’t very supportive—being five minutes late led to what felt like a scolding, almost like being sent to the principal’s office. Given that experience, I’ve decided to seek care elsewhere

To say this man needs to learn a little bedside manner is an understatement! I match energy and gave him his attitude back. He was a little better when I saw him again.

He is very rude, unprofessional. He perforated my colon during a colonoscopy. Sent me home the same day and I wound up in the hospital.

Great doctor, great nurses, great staff all around. Thank you for being so kind, as someone with anxiety, it is refreshing when people care and make situations as easy as possible.

Dr. Fesenmyer has shown great care and expertise while dealing with my elderly mother. His staff is courteous and professional while expediting appointments and procedures. I can not say enough good things.

I was unable to complete a sentence, he cut me off mid stream and then made his own assumption of what I was able to say, acting like I was the one who was causing all my problems with my abdomen, the doctor has a very bad bedside manner, his nurse on the other hand is a delight, she listens and is very caring, the doctor could learn a lot from her.
