12/27/2022

Dr. Gengler is awesome. I was diagnosed with colon cancer in May of this year. His staff got me in within a week of my diagnosis. Once he looked at all of information, he wanted to get me into surgery right away. North Kansas City Hospital was booked for over a month, he had his scheduler work her magic and make it happen right away. I had my surgery less then a month after my diagnosis. He took his time to explain how the surgery and what to expect. He was so kind and caring and answered all of my questions. Surgery was a success. Dr. Gengler is a very kind and compassionate doctor and he really cares about his patients.

12/04/2022

Dr. Gengler is a caring and kind physician who takes the time to educate the patient of the procedure and expected outcome. He works well with the other disciplines to ensure continuity of care.

08/06/2020

Thorough. Listens to his patients. Makes sure you understand all your options. Great bedside manner. Would unequivocally recommend to family and friends.

07/04/2018

I just had my first consult with Dr. Gengler, and I can truly say that he is very caring, attentive and open to listen to your concerns/questions. He takes time to explain things to you and ensures you understand the information he provides. It was truly a fresh of air to see him (after spending time with other doctor's - not at this location, who seem to give me about 5 min of their time) and feel very confident on having him perform my surgery.

03/02/2018

Very attentive and kind, would recommend to family/friends

09/29/2016

Very caring Doctor and super nice guy. Would let operate on any family member.
