Dr Waterbury was amazing, as were all of his staff. I felt very confident in the testing he chose to do, and any follow-up he recommended. He, and his staff, listened to my concerns, answered my questions, and put me at ease. I have recommended him to several friends, and will continue to do so.

Everybody seemed very personable and very interested. We were really impressed. Thank you.
September 20, 2022
I would've had a pre authorization on a stress test. That I was going to have. Rather than just going to the doctor and then come back and say Oh pre authorize this. And I had the appointment set up 6 weeks ago. That's what I would have done.
September 15, 2022
Had to wait a long time to see provider.

June 22, 2022
I appreciate that the clinic is held in LeMars and I don't have to travel to Sioux Falls. I don't know why they thought I missed my appointment. I was there early and had preregistered online. I think I responded to all the messages sent to me.
June 20, 2022
They have a great group of people working for them
June 17, 2022
The only thing I would say to improve is I was told I would receive feedback later that night and I never did receive any feedback or call.
June 17, 2022

June 15, 2022
Entire staff was positive, and easy to work with.
June 06, 2022
You should have checked into my insurance before I had my appointment to get that approved for my stress test. It was my feelings, it likewise with my driver. Okay.
May 24, 2022
Dr. Waterbury is a very competent and professional eye doctor and I have a great deal of confidence in his abilities and his also the the way that he explains things so that, that I can understand.
May 23, 2022
Dr. Waterbury and Becky were awesome. We felt valued and listened to. NCH and Avera Heart will always be my choice.
May 06, 2022
Yes, I liked them very much. The kept me informed, made it sound like they really know what they're doing cause (INAUDIBLE) e. coli or whatever, I forget names and numbers, but what I'm going in for Wednesday, and we went over (INAUDIBLE) or whatever, then why they're doing this and that, and there's two ladies that took my blood pressure, and the nurse was writing it down. So, yes, I liked it very much. Kept me well informed (INAUDIBLE).
May 06, 2022
It is frustrating having important medical tests performed and when done you are told that you will be contacted with the results. When you are contacted, it is by a nurse, not the doctor. You then get a full report available on Avera Chart that requires a person with a medical education to understand! It would be nice once the results of your tests were available you could get the doctor to explain the results and outcomes! Doctors keep recommending the tests and procedures but they are not then available to explain the results. You basically get told by the nurse to come back in a year or whatever. Not sure I am very willing to come back!!! Thank you!
April 26, 2022
We all make mistakes but I waited over an hour for my 1st scheduled test. My avera chart was the same from the day I made the appointment through day of appointment. Even my welcome letter had same times on it. My final test was even over 20 past scheduled times. I was very disappointed with this experience especially after hearing tons of great reviews. But on the other side of the coin I really felt like they cared and listened to me and took the time to get to know me. I am switching from elsewhere to avera as I feel it is the better choice for me and my situation. I do hope that it continues to be about patient care and not how many people can we push through in a day. I actually felt like a person and not a number.
April 22, 2022
Clear explanation of plan going forward
April 14, 2022
Everyone was a delight. Very knowledgeable and very polite. They were all so engaging.
April 12, 2022
I would give him a good a much better grade, Than the last a doctor that I had been seeing which was not even functional so he did a very good job. Thank you very much.
April 12, 2022
I so look forward to Dr Waterbury reviewing my heart records from double bypass in 2018 to current tests to try to find out why I am blacking out with no notice if it is my heart causing this! Never had this happen before but I liked him a lot!
April 08, 2022
Um, yes. Everybody was professional and very...nice, and the staff and everybody else. Thank you. Bye.
April 08, 2022
Yes. Dr. Waterbury was absolutely amazing, but this time, when I was supposed to see him I wasn't able to make it, so I have to reschedule, but thank you so very much, and absolutely like ... you are ... your facility is amazing. Thank you.
April 08, 2022
Yes, not just the doctor, everybody that I talked to there, the nurse... two different nurses. The people in the scanning area, the receptionist. Everybody was extremely professional. Very, very pleased with my experience. This was my first experience and went very well, very timely on everything. It was great. Thanks.
April 06, 2022

February 09, 2022
Top notch medical facility with top notch staff!
February 08, 2022
From Dr. Waterbury to all of the staff who worked with me. My time at our Central heart was exceptional. I have really nothing else to say.
February 04, 2022
Yes, every... everybody was so nice to us. To myself and my wife. And they were interested in what we did. How... how we got there. Where we were from. Thank you very much. Bye.
February 02, 2022
We understood our appointment was at 2 and we were to come a half hour early when it turned out our appointment was at 2:30 and the 2 o'clock was so we'd be there half hour early. So we set a long time waiting for our appointment, and when we received the phone call, it did not tell us a time of our appointment and also it did not tell us that we would not be able to have our daughter and her husband with us for the appointment, but when we get there, there's just one allowed. Goodbye.
February 02, 2022
The staff I had were very knowledgeable and friendly. I would defy recommend to anyone I know.
January 31, 2022
Both the nurse, Becky, and Dr. Waterbury were very good and helpful
January 27, 2022
The care was phenomenal. The only thing I would suggest is that after everything is done, I could have spoken to the doctor instead of the nurse for results. There were questions that came up, and I would have liked to have been able to ask the doctor. Thank you.
January 25, 2022
Export doctor made me feel very at home. Answered all of my questions. I understood everything after I asked him. Felt like I had excellent care yesterday, and I'd recommend it to any of my friends or family.
January 21, 2022
Good professional people at the heart hospital!
January 12, 2022
Yeah, I went in for my prescriptions today and we can't afford going on $500 a month the Eliquis, I think we were very, very (INAUDIBLE). The whole place is very, very likable. Very, very helpful. Very kind. And so, we're definitely going to get a hold of them to see if we get a find a cheaper drugs because we can't pay the 5 something a month. So I think my wife's going to try to email this company, so Yeah, in the next couple days a week whenever it works out for us. Thanks a lot for everything.
January 11, 2022
Took to long schedule problem halfway through on your part however l thought it was handled well just very inconvenient
January 06, 2022
Well, they listen to me really well and I really like the doctor up there and the nurses they were real thorough.
January 05, 2022
All of the people involved were professional, friendly, and efficient. First big appointment that has been finished before 'twas scheduled to start. I do realize the prior one was cancelled. Bad part was I could not see all the smiles. Great overall experience.
December 20, 2021
Dr. Waterbury was very concerned with my heart health. He explained to me what I wanted to know. I am thankful Dr. Waterbury is my cardiologist and I feel reassured if and when I have heart issues, he will take care of me. Also, his report was on my Avera chart portal that very same day, which I appreciate very much.
December 20, 2021
I think it was a wonderful trip up to Sioux Falls. I would recommend him to anybody. Okay.
December 13, 2021
Excellence from everyone!
December 13, 2021
Yeah, they told me and explained it well. Yeah, explained it well to me, what happened and stuff like that.
November 23, 2021
Dr Waterbury and his staff are so nice. Very good service.
November 17, 2021
It was a great experience. I did not expect such excellent service and assistance.
November 17, 2021
The only things that frustrated me were filling out all the paperwork ahead of time and having to do it all over again when I arrived. Also was supposed to have a test prior to seeing the Dr. but evidently notes weren't entered correctly from previous visit so they wouldn't schedule prior to seeing Dr.
November 17, 2021
Yes, I really thought that the experience was very good. I thought they did well for me, but I didn't get any information back. I thought maybe I'd get a call today or even yesterday... late last night, or something. About the information that they were able to obtain for me. And what I needed to do, to help myself out here with my pain that I had. So thank you.
November 08, 2021
Didn't have to wait long for scheduled appts. Doctor, nurse, person who did echocardiogram were very informative and to the point.
November 08, 2021
I was impressed with the efficiency of my appointment from the time I registered to the time I saw the doctor. It was amazing and unusual. I was very satisfied. Thank you.
November 05, 2021
the whole hospital was amazing. He saved my life, and I thank you. Bye.
November 05, 2021
Yes, I Heart Hospital is definitely the place to go. If you have heart issues, they definitely have basically probably saved me. Thank you.
September 29, 2021
My original apt was for 830. They called the day before to reschedule me to 3pm. Because it was too late in the day to the stress test I now have to go back next week. Should have rescheduled me for another am appointment in the am so I dont have to drive 4 hours again. Very frustrating as I live alone and have to find someone to watch my dogs when I travel to Sioux Falls.
September 27, 2021
Professional & prompt. I change from another area provider due to being more patient focused.
September 09, 2021
DR Waterbury was quite helpful.
September 09, 2021
The whole experience was great. Every one was extremely polite.
September 07, 2021
Our experience there was excellent. I couldn't ask for any better from the, the doctor to the nurses to the other complete staff. Both my husband, and I said how helpful they were all kind they were and how they were just there to help everyone. So, it was an excellent experience and just very pleased to have been there. Not that. I like to be there for health reasons, but if you have to be there, it was a great experience, so I am very appreciative of each one of them. They did a wonderful job. Thank you very much. Bye. Bye.
September 03, 2021
All the staff that we came into contact with for my appointment were very courteous and informative. Answered any questions that we had. The echo tech was notably easy to work with and knew her job well. Good experience all around. Thank you.
September 01, 2021
Each of the staff members that greeted me. Greeted me with an incorrect name pronunciation. I corrected it once but everyone after that, not including the doctor. Got the name pronunciation incorrect.
September 01, 2021
very nice and friendly staff ...Dr was great ... this was our first time there!
August 23, 2021
Dr. excuse me Dr. Waterbury was very, very professional, and he was very caring to the patient and he listened and he never tried to be in a hurry. He Dr. Waterbury ask questions to the patient. The patient would, you know, maybe could hear him maybe not but Dr. Waterbury would lift his voice for the patient so could hear him. And then the patient ask for some directions of things, and he was most willing to to help. So, I don't know if I've ever come across a doctor as good as Dr. Waterbury. Thank you very, very much for Dr. Waterbury. Have a good day. Goodbye.
August 20, 2021
August 19, 2021
Past was good, thank you because you treated me very in a very good way.

Very pleased with both nurses and doctors and their concerns for as the health of my heart.
July 22, 2021
although I was in the clinic for over 3 hours I didn't have to wait for hardly anything... I did have to wait 35 minutes for the Dr. to come and do my stress test.. which lasted 7 minutes.. other wise I was very pleased.
July 22, 2021
Great people who care!
July 21, 2021
Dr. Waterbury met and exceeded my expectations of a quality doctor/patient interaction.
July 21, 2021
Yes, I had a lot of questions to ask about my heart because I don't know a lot about the Heart and I felt that Waterbury answer the questions that I asked him and besides that, I thought that his nurse was very efficient, thank you.

Thank you to everyone.
July 01, 2021

I can honestly say, I recommend this hospital for any heart patient I am completely satisfied and wonderful. I've been blessed I'm very happy with all the surgeons, and Dr. Waterbury, and all the follow up, and I thank you.
June 29, 2021
Nurse was rude. Provider did not address concerns
June 21, 2021
Absolutely everyone was friendly, professional, and answered any questions I had. Top notch group!!!
June 21, 2021
I thought my experience was exceptional. I was in and out, the people were knowledgeable, even rate them coming in, and the first person at the guest desk, offering to assist and then getting checked in, and the nurses, the doctor, the experience, as well, and they were respectful, knowledgeable, and felt like they were caring and understanding. I walked out of there feeling very comfortable with my experience, and felt like they had done exactly what I needed them to do.
June 18, 2021
Please lose the masks - a patient's facial expressions can tell a doctor/nurse a lot too...
June 18, 2021
Yes, I'd like to thank Doc, for all the information, you give me and I was very satisfied and thank you very much. Have a great day. Bye.
June 15, 2021
Well, I think they did an excellent job. They were very respectful and they thought about my condition and they seem. They manage to cure it or make it better. And that's, as far as I know, he's there next level. That's an excellent hospital and I recommend it to all my friends.
June 03, 2021
I appreciate that I was listened to and each one who was involved in the tests was clear, friendly, precise and thorough. Thank you for helping me understand my condition and how to live with it.
June 03, 2021
I would like to hear back from him the next day rather than waiting over the weekend.
May 28, 2021
thorough and respectful. cheerful and helpful
May 20, 2021
Well, they took care of me in a very, very good manner and got me out of there in a hurry because I had a 500 mile trip to go home and they were very, very good at their work. Thank you.
May 19, 2021
Dr. Waterbury and the staff are very professional and very competent. And certainly extremely caring and I'm just extremely pleased. And that... that he and his staff are my caregivers. Thank you.
May 04, 2021
Yes, they were extremely busy today I was in there and I have to say they were all courteous. They they got us all through and a manly fashion or an orderly fashion and Dr. Waterbury was real attentive to my needs. I ask him questions and he told me straight up, he answers. So I hope this helps you. Thanks.
April 29, 2021
Great group of people!!!
April 27, 2021
That was my first experience with the doctor and I was very happy - well, I shouldn't say that, but I was very happy with all the results and his synopsis of what was going on with my health care. So he did an awesome job. Thank you.
April 26, 2021
When the test were done we needed more information about results in language we can understand. Everyone very helpful and pleasant.
April 22, 2021
Avera is outstanding. Dr. Waterbury, his nurse, his assistant, kind efficient. The facility is wonderful. I could not say a nice, enough nice things. I've always had good medical care, but Avera leads the top. So, thank you all very much.
April 16, 2021
I was one of the unlucky ones my doctor had a emergency I just wanted to talk to him more after the test but wasn't given a chance. Over all it was a good experience. Thank you
April 09, 2021
They always informed me as to what they were doing and why. Also treated me with respect and kindness all along the way.
April 05, 2021
He was great to visit with I ask you a few questions related to my heart condition, and he helped there and his assistant was very good. Also, just extremely highly qualified people. Thank you.
March 30, 2021
The clinical care from, all the way from the patient care tech, to the nurse. There was a CNT, and the cardiologist was absolutely excellent. The only thing that I would just give a suggestion. It's not a complaint, but I have a suggestion to really lean out your process. Like I had to talk to three different people to get checked in. I thought that was a little interesting. I actually am a patient access director, and I just kind of shook my head a little bit at the amount of resources used to check people in, and then they asked the same questions over that, you know, you've recently completed. So anyway, that's my only suggestion, it's not a complaint. It is just a suggestion. I think that everything at the Heart Hospital is excellent, and we'll just look at leaning that front process out a little bit. Thanks. Bye.
March 26, 2021
Everybody was extremely friendly and the flow from one area area to the next was very smooth. My experience was very pleasant.
March 25, 2021
Dr. Waterbury was very much on time. He was quite thorough in his explanation of my situation and he provided a good plan for treating me in the future. His nurse worked with me closely to get an appointment here in Spirit Lake to get my my what do you call it echo cardiogram my cardiogram whatever you call it the next scan that they were going to do. Appreciate his work very much. Thank you.
March 10, 2021
I was well satisfied
March 08, 2021
Dr. Waterbury was one of the kindest most compassionate doctors I've had the experience to be a patient of. He was just he explained everything very clearly, he treated me with respect, and I just really think he's great.
March 08, 2021
Everyone was awesome starting with the 1st person in the door and everyone that helped me after that.
March 04, 2021
I can't think of anything to improve, we were very satisfied with the...with the treatment and care.
March 04, 2021
March 03, 2021
Each time I have a dr appointment I am asked to bring all my medications and no one has ever asked to look to at them . It is a real hassle carrying them around . Why have this requirement? Thank you!
March 03, 2021
I'm just a little disappointed that I didn't get the results of my scans. I understand, I wouldn't get them the first day. But they told me I would get them the next day and I still haven't seen the results.
March 03, 2021
It was my first appointment with Dr. Waterbury and I was pleased to get to meet him -- I am confident our next appointment will be as thorough as was this meeting --
February 26, 2021
Very good experience.
February 25, 2021
Felt very confident with the nurses and the doctor.
