February 26, 2016

great

February 22, 2016

Dr. John Ryan is the reason I am alive today. He is the quintessential physician. His memory, of course, is hard to believe. Of hundreds of patients, I can ask him dates, times, diagnosis, what was under consideration, virtually anything about my medical history and nails it. It is clear to me that before he comes in to the exam room he has reviewed my chart and discussed my case with Mrs. Keeney. He, like Carolyn Keeney, has awesome technical/medical skills and possesses those, difficult to articulate, interpersonal skills that have such a profound beneficial impact on the patient. He addresses not only medical issues but is mindful of me as a whole. I trust him with my life and I believe that it is because of his skill, attentiveness and courage (fighting for me) and love for all human life that I am alive today. He has been a blessing to me.

February 20, 2016

Found out from the exit paperwork that I should not take flecainide.

February 16, 2016

Dr Ryan shows compassion while sharing my challenges and helps to put them in perspective.

February 13, 2016

Dr. Ryan is always treats the whole person. He takes the time to understand medical and social issues that may impact the wellbeing of his patients.

February 01, 2016

Both Erin Michaelis and Dr. Ryan were extremely good about imparting information and answering my questions. I have a great deal of confidence in them as my care providers.

January 23, 2016

Very pleased with Dr. Ryan. He was very interested in helping me out.

January 20, 2016

Dr. Ryan and Jacqueline, PA-C, are consistently kind, compassionate and very comprehensive in their evaluation and progress at each clinic visit. Heart failure and pacemaker issues can be complex and Dr. Ryan expresses concern and care for me as a human being and compassion for my husband, who is also a caregiver. They show us that they care and they advocate for me and for my family in achieving the highest quality of life and in helping to navigate several healthcare providers on our team. Thank you and forever grateful.

January 17, 2016

Really liked Dr.Ryan friendly, made us feel at home. Fellow from Thailand-hard to understand felt he was not understanding what we were saying. He was nice enough

January 04, 2016

Dr. Ryan is thee best Cardiologist ever, I would HIGHLY recommend him. One Friday, (late afternoon)I went to the clinic and he was the only physician on staff. He still found time to come out and speak with me. He took me into a private room as we discussed my diagnosis. He is phenomenal!

December 13, 2015

Best team of any Dr's I see at the hospital.

November 24, 2015

I was very impressed with Dr. Ryan, his office assistants and the tech in who completed the electrocardiogram

November 17, 2015

Dr. Ryan, Hatton and Mayeax were excellent. Took plenty of time to discuss all issues and had great report with me. It is a pain to have to drive down from Idaho for such care but well worth it to have such great medical expertise available. Keep up the Great Work!!

November 16, 2015

in the last 14 months since i have seen 5 other providers he is the only one who really listened to how i feel about my situation and took my feelings about what i felt was best for me into consideration . he took the time to listen to me and how i felt like i was doing and what i wanted for me and my future with my health care. we went over what we are going to do for now and if their happens to be a long term plan change we will get to that when the time comes. finally after the last 14 months of me going threw my situation i have found a dr. who will listen to me and take what i say into consideration about knowing that i will be ok if i try it my way. thank you dr. ryan you put my mind at ease

October 19, 2015

This visit was the best yet. I simply love this team and I know for certain that they're outstanding in the field. I tend to research everything and everyone and they stand up to some tough scoring by me. I feel far more hopeful and encouraged that all will be the best they can make it be.

October 13, 2015

I would (and have) highly recommend Dr. Ryan and his staff to friends, family and acquaintances! I trust (and trusted) them with my life!!!

Dr. Ryan and his staff are excellent they are a credit not only to your hospital but to cardiac medicine as well.

October 04, 2015

I was very pleased with the information that I received and how my questions were answered.

September 10, 2015

I am still not fully understanding the signfiance of my problem

September 04, 2015

These are the best Doctors that I've ever had. I know this because I'm one of those patients that is sensitive to medication. That 2% that you hear of so, things don't always work with me that would with 98% of people. I have had so many doctors that have just given up saying well it's just medication side effects you just have to deal with it. Dr. Ryan & Erin Michelas never give up they keep trying until they find what works best. They are AWESOME.

August 15, 2015

Dr. Ryan seems to understand how his care impacts his patients. I feel confident in his skill as a physician as well as his vast knowledge of heart/lung disease. He has a calm manner and is able to help me feel at ease and comfortable.

July 31, 2015

DR.Ryan and staff were very throough and took time to explain. One of the best experiences I have had at U of U clinics.

July 20, 2015

Erin Michaelis and Dr. Ryan are excellent care providers I appreciate that they actually listen to my concerns and are honest with me. I am on day #4 of the opsumit without any crazy side effects. They all chipped in to get me a pill cutter. They went above and beyond their job as a health care provider. It made my heart smile to know there are still kind people in this fast paced world we all live in.

July 18, 2015

Dr Ryan is an excellent caring doctor. I really appreciate him.

July 04, 2015

I deeply appreciated the experience after having had a terrible one at another non U of U provider. I feel I can face whatever needs to be faced now.

May 09, 2015

Dr. Ryan and his team are AWESOME! Very professional, very kind and didn't feel rushed.

April 28, 2015

My wife and I appreciate that Dr. Ryan spoke directly to our special needs daughter and not to he through us. Also that he took the time to speak to her.

April 27, 2015

I'm 51 best experience ever

April 06, 2015

Cardiology is always great!

April 05, 2015

Dr. Ryan asked me how I was feeling, but it doesn't seem like he really cares as he didn't add any new medication or treatments when I told him I never feel good anymore.

April 03, 2015

Dr. Ryan is an exceptional physician. He embodies those qualities that patients wish for in their doctors; intelligence, technical skill, knowledge in (truly) best practices, compassion, good communication, personability, humility and kindness.

March 30, 2015

Dr. Ryan and his staff are awesome! I feel confident that he is interested in making me feel better and is taking a collaborative approach involving my other cardiologists.

March 14, 2015

Dr. Ryan (and many others) were very diligent and thorough in finding the diagnosis for my problem. I am so very grateful for that

March 14, 2015

Dr. Ryan was so approachable and genuinely kind. He seemed to have really read and understood many of my medical records and complicated cardiac history, including extensive iatrogenic injury leading to heart failure. Yet, he did not rely on records that are often inaccurate; he took time to ask me to tell me story, in my own words and made the patient experience one of compassion and caring. He is a man of great compassion, knowledge and was on top of everything, with regard to logical next steps to identify factors that are contributing to progressive symptoms. He is so intelligent and exceptional in every way. He is the physician that every patient and family member, wishes they could find during times of suffering. Thank you.

March 03, 2015

Dr. Ryan made it clear that my treatment would be a team effort that would include my other doctors Dr. Selzman and Dr. Ranjan. I appreciate the communication between them.

February 23, 2015

Dr. Ryan is kind and I feel secure he provides treatment that is in my best interest.

February 19, 2015

The doctors did not push cholesterol drugs given my excellent "good" HDL stats. I REALLY appreciate when doctors do no push drugs.

February 18, 2015

I spent more time with Caroline Kelley and she answered most of the question and gave most of the info. More so Than Dr. Ryan. Dr. Ryan was still professional and I would refer him too.

February 03, 2015

I was very impressed with all the staff and doctors. There was no problem with anyone.
