What People Say About Dr. John Madigan, DO
RecentMost Helpful
I don't know what to say about this amazing doctor. my mother-in law has been seeing Dr. Madigan since last year. He takes the time to talk to us and explore different alternatives. He treats her like a family member. It does not matter what time you call, night and day, he will return your call the same day. He shows concern about his patients. he goes above and beyond his call of duty Dr. Madigan may God bless you and your family.

Great Doctor. I wasn't feeling well and went to see Dr. Madigan. He sent me for several tests and treated me. 10 min wait time in the office and he takes his time and answers any and all questions that you have. Highly recommend Dr. Madigan. Thank you.

Dr. Madigan and his staff were very professional. The office is spotless, very little wait and everyone was very nice. It was my first visit and I went to see Dr. Madigan as a PCP -- and he was awesome. He listened, took notes and asked lots of questions. He was very detailed and followed up the next day, I felt very comfortable. He made me feel at ease and explained everything. I would definitely recommend.

It was my first time visiting him and I was getting a little impatient since I had been waiting for a while. But the moment he came in, he apologized and took his time examining, listening and explaining everything. I would definitely keep him as my primary doctor.
