As a first visit and with lot of anxiety out of what we would find out and the reality of it all, my experience was very positive. Right on schedule and very professional. I felt I was in good hands and console.

Following my visit, I returned to my home pharmacy which had two prescriptions that I was not prepared to accept because I had not been informed such prescriptions would be supplied for my use. Following two phone calls to north central, I finally spoke to a nurse who told me not to take the two prescriptions; that they were not meant for me. I was confused with this and I remained confused. I did not take the scripts. This is not a good situation to find oneself involved.

Dr Halligan and the entire staff were awesome. Listened to what I had to say and explained everything regarding tests to be done and what needed to be done.

Yes, you was on time and a has a very well organized office and help and everything went good and they help. I'm an old guy and kind of and down but they really helped. They took care of my real good care of me and did everything they could for me. I was real real happy with them.

Yes, our visit to North Central Heart was very comfortable. We were well taken care of and did not have to wait very long to see the doctor. Comma we felt that there was adequate visit with the nurse, but more than adequate visit with Dr. Halligan. He spent as much time with us as we wanted. We did truthfully enjoy staying at the little motel hotel there, which certainly helped us being that we were coming from 100 miles away. Thank you again so much, and we continue to spread the word on North Central Heart.

The most professional run medical facility that I have ever seen or even heard about. No waiting forever in the waiting room. Very nice experience!

Yeah, I was well pleased with a care I got and I would have anybody in my family go to that hospital. Thank you.

The staff at NCH are so helpful,friendly and knowledgeable. We are incredibly lucky to have such a facility so close to us for needs.

Doctor was very caring, listened, and understood, and even offered other suggestions, and was very concerned. Very understanding, like I said, and he was very...he gave his time and did not hurry me.

Dr. Halligan was a very concerning, caring doctor I really liked him a lot and I can't really think of nothing that he can improve on. So you guys have a great day.

Seems knowledgeable. I still has some concerns, but I guess as we go along with this cardiologist, it's my first time seeing one. I guess I'll understand things. I'm just still kind of concerned if I have a true heart condition or not. I guess I'll find out after the dial patch comes off, but I'm still concerned with the heart situation. Thank you.

Thank you for being able to get me in to see a doctor on such a short notice.

I think the hospital is doing a great job getting patients in and out considering the damage from the tornado. My mom doctored there and everyone was so kind to her.

Dr Halligan was such a great Dr. I already referred him to a friend. The nurses that took care of us are top notch. I represents that checked where also nice. Thank you all!
October 04, 2019
Yes, I think that when,you know. A personal physician sends a patient up there. They don't expect to just get a medical review and no testing and so I travel 3 hours and a 20 minute visit. And told to come back in a week in two weeks for stress test and all the other blood work and and all that. I don't understand why they couldn't do it the first visit, you know. And that's it.
October 04, 2019
I appreciated the care that each person I met took of me the nurses in the attendance and everybody who was in intake and it's behind the desk and Dr. Halligan as well, I felt that each one was a good listener and respected what I had to say.
September 23, 2019
Yeah, I'd like to comment on the care I received the recovery room was very good. The girl there was very friendly just really made us comfortable and we appreciate that very much.

Appreciate the effort that was put forward and did provide me with some information that I could work with. I thank you for your time. Good day.
