Hi, Dr. Halligan was very very thorough. He was very kind and respected my questions when I asked them.

This is the most well organized group of folks. The day went like clock work. And being told what the next step would be and what to expect. I was so impressed more so than I was back 7 years ago. Keep up the good work.

I think Dr. Halligan is fine. The only recommendation I would have is it would have been good if he had called me with the results. In the event I had questions I didn't I mean everything was fine. The nurse did a good job, but I think it is helpful to be able to speak directly to your doctor. Once you've had a test like that. Thanks.

Both my husband and I are very pleased with the Heart Hospital. Dr. Weiss has been a godsend for my husband, and the cardiologist team that I'm seeing, I couldn't be more confident that things are going to go extremely well. Thank you.

It was great. They did the EKG first and then when I saw the doctor he had that information, plus all the information and he was very friendly and personable. Thank you.

Yes. I thought I had a good experience with the Dr. I felt very comfortable. Not so scared, and I know everyone is wonderfully good. I would recommend the hospital to anyone. Thank you.

I think the provider didn't listen to me very well. Just wanted to prescribe a pill for me to try to correct what was going on, and I don't think that was the right path for me, so I will not be taking the medication he prescribed, and I will not see him again. Thank you.

It was a very thorough exam that I had yesterday, and I was very pleased. Thank you.

I'm concerned about my medication. They don't seem to be accurate according to the way my bottles prescribed. I don't know how to give you that information that doctor would be able to see.

Dr. Halligan did a very good job with me. I appreciated his input and explained everything to me correctly, and I really appreciated it. Thank you.

Everything went well.

The staff performing my tests were wonderful to work with. When I was complete - when tests were complete and I got a call about the results and things that needed to have happen it was very short. I didn't under ... it was hard to understand what to - what was recommended, what the courses of action were. It was an incomplete follow up. Limited opportunity to ask questions and I did not talk to my doctor about the results of the test. And so I'm I'm uncertain and uncomfortable with the results and the recommendation because I did not talk directly to the doctor about those results and recommendations and that adequate opportunity to have a face to face conversation about those results.

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.
May 08, 2020
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.
March 13, 2020
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!
February 11, 2020
Yeah, I was well pleased with a care I got and I would have anybody in my family go to that hospital. Thank you.
