Dr. Callahan was kind and professional. I appreciated that he took the time to listen and hear my story and my concerns. I liked that we were able to discuss and decide on the best way to treat me. He went out of his way to accommodate my situation and get me into surgery the same week so I didn't have to travel all the way back to Cleveland from Illinois. The anxiety I have felt for the past 8 months disappeared after my appointment with him.

I wish that "exceptional" was an option. Dr. Callahan did the visit at the end of the day but acted as though I was his only patient and that he had all the time in the world. He truly combines the science and art of medicine. His clinical expertise is well recognized. But he is also the most caring, understanding and empathetic doctor. We feel blessed to have Dr. Callahan.

"Ease of getting the care you needed" was fine. I am aware that nearly all doctors and their staff are overloaded. I am concerned about getting timely care since I have numerous medical conditions. It's easy to schedule an appointment, it's not easy to get an appointment that's not 5 months away, and in some cases, my doctors' calendar's aren't even open for the next 6 months.
