A routine follow up after colorectal cancer surgery with Dr Keller is anything but routine. He is prepared to answer any questions, and listens to my concerns. He is awesome! Great bedside manner, wonderful office staff.

I think it was not good. I got a blood cloth removed about 3-4 weeks after it surfaced. Here I'm 2 years and 5 months after the operation still having horrible pain on the operated area after sitting for an hour having to work standing by my desk almost the whole day to avoid the pain. I read later on several medical webs that for the removal to work it has to be done within a week of surfacing or otherwise wait till it goes away by itself so you judge yourself...

Just called at 4:20 in the afternoon. Samantha takes my insurance info and assures me they take it. She puts me on hold telling me she's looking for an appointment. About five minutes later another staff member comes on the line and tells me Samantha had to leave and she can't take the appointment nor can anyone else in the office, they'll call in the morning. The other person is reportedly in a meeting. Truly crappy office staff.

After being diagnosed with colon cancer I was referred to Dr Keller by Dr Muhammad Ali. Dr. Keller's expertise and professionalism is the reason I'm alive today. A Robotic Sigmoid Colectomy was performed through small incisions. After the procedure I never suffered much pain and I recovered quickly. I would recommend Dr. Keller to my family and friends.

Dr. Keller is a professional in all of his actions. He explained clearly to me at the first appointment what my diagnosis meant, created a diagram and treatment plan; and answered any questions I had. When the initial day of surgery came, I was still wrestling with a decision to have a mediport placed at that time or not. He patiently talked me through my concerns ( when he might have wanted to scream !). He has assembled a staff, like himself, caring and professional.

Dr.Keller has been great dealing with my issue, started working with him while pregnant of both my two youngest children. During a pregnancy a Colon & Rectal surgeon or gastroenterology Dr normally don't attend pregnant moms. I was very lucky to find him and after having my two babies he operated me and has kept up with my healing process. Their is very few doctors that I can say are so caring and patient as Dr.Keller.

Dr. Keller was my father's surgeon and we owe him gratitude for not only his surgical ability but also his compassionate care and bedside manner. He patiently listened each time he visited us in the hospital bed and gave us family his undivided attention and addressed all the questions. My father was in the hospital for 22 days and spent two weeks at the Skilled Nursing Facility to gain his strength and mobility back. He came home two days ago. It was a journey and we thank Dr. Keller.

Doctor Keller was my surgeon when I was diagnosed with stage 3 rectal cancer when I was 30. He successfully removed my tumor, and I recently celebrated one year of being cancer free because of him. He's a great and caring surgeon with amazing bedside manner. You never feel like you're being rushed during appointments, he takes his time with his patients. I highly recommend him and his associates.
