When certain items arose, Dr. McCullough would call me at home. I am from Michigan and go to Cleveland Clinic now quite often with other clinics.

Dr McCulloch is the best doctors we encountered during our long time with Cleveland Clinic. He is very professional, empathetic, caring, speaks to my wife & I in a manner that is easy to understand. He spends the time needed to speak to all of your issues-not the usual 15 minute slot. He does not rush you. We learn more from Dr McCulloch than from anyone else. We wish him well in his retirement, but he is. gem and will be missed. Our appointment didn't appear on his schedule, even though it was set months ago. He apologized & saw us at our scheduled time. This is just unheard of. It would have been easy for him to just have us reschedule, but he didn't do that. We really appreciate the counsel he has given us.
