Dr Ryan cared for my mother until her death at 96 years of age. His patience and courtesy to her touched me deeply. Dr Ryan is now my doctor, as he was mothers. I am receiving the same excellent care as I suffer from the same health issues that finally claimed my mothers life. I am confident the care I am receiving will keep me alive as long as possible. That confidence gives me great peace of mind.
Dr. Ryan and staff are very kind and attentive to my health.
Awesome care
Doctor Ryan is very knowledgeable. He is very pleasant but gets right to the point. But from the minute you enter the room, you are made to feel like they can't finish with you fast enough. If you need or want help from him, plan on waiting a couple of months for an appointment time.
I wish all doctors listened as well, explained things as well on a level I can understand, and cared about their patients as well as Dr. Ryan does. It makes health conditions a lot easier to deal with.

I would recommend him to anyone!! He is the best doctor I have ever had!!!
good experience
Dr Ryan and listen well and give great feedback
I wish he would have contacted my primary care doctor and explained why I was taken off a medication she (primary care) had me taking it would have prevented a great deal of confusion and problems for me
Was very direct about what needed to happen so I can get my diagnosis

Dr. Ryan took the time to explain things to me in laymans term. He listened to my complaints and took appropriate steps to correct the problems.
Knowledgeable and caring
I was discourage and had given up and was waiting to die. I didnt want to see another doctor. His kindness and willingness to explain my condition changed everything for me. Even though there was no cure, I felt he genuinely cared, not that I hadnt felt cared about by others, he was just different. From that first appointment on, I decided to focus on living rather than dying. I was originally diagnosed in 2000 with pulmonary hypertension and continued to decline. However, after my appointment in 2014, my attitude changed. I attribute that change to him. His kindness and caring were critical. I have survived well, for over 20 years, and I give him credit. I have learned that attitude and survival may be closely tied. It has been so for me. What he has, they call bedside manner, and has that in abundance. I have heard other patients express the same feelings. He is a good man and an excellent doctor. Obviously I highly recommend him.
Dr. Ryan always listens to my concerns or issues and addresses them immediately.
Dr. Ryan is the best! I have had other cardiologists in the past he is by far the best one! I have had him for 6 years now enjoy our yearly checkups! He truly cares about me and my family always asking about them as well as on my heart. Our checkups are enjoyable. Where you are checking up with an old friend. He is always willing to listen to any concerns I may have too. I trust him with my life! I am so very thankful to have him as my doctor. This past visit he said "Well my friend your heart is doing so well sadly the next time I will see you is in three years!" Never have I felt so happy about that news and a little sad at the same time. I will always recommend Dr. Ryan to anyone that may need a cardiologist. He is the best cardiologist for me! I am thankful to have him as my amazing doctor.
Incredible medical team. I am so grateful.

A skilled and caring professional who has greatly improved the quality and enjoyment of my life. A truly exceptional physician.
Dr Ryan is knowledgeable, thoughtful and caring.
He spent approximately 2 minutes with me, listened to my heart for 2 seconds, said it sounded good and dismissed me. I've never experienced a more incompetent doctor and the appointment was a total waist of my time. I'm a fan of U of U docs but will never return to dr Ryan.

I have recommended Dr. Ryan (and team) and Dr. McKeller (and team) to at least 30 people as of today. I will continue to do so. Dr. Ryan has this ability to make you feel that you are going to fine and in great hands. I trust him (which is crazy bc I trust very few people). The University of Utah Hospital is very lucky to have that man. He saves lives....
Dr Ryan demonstrates the essence of a physician, he combines the art of caring for a patient with the in depth knowledge of medicine that gives confidence in his care. I can not say enough good about Dr Ryan and his team.
Great Dr. Very respectful and explains things so I can understand I would highly recommend him to my family and friends
Dr. Ryan is amazing. I trust him with my care and know he cares about my quality of life. He takes the time to listen, researches options and enlists me in my care decisions. I tell anyone I know suffering from cardiac issues about him and his clinic.

I believe I am in the best of care after meeting with Dr Ryan. He let me know he was familiar with my condition and in fact, he knew what I needed medically. I am confident he was the right choice for me.
I enjoyed his very kind manor in which he treated me. As I did not get to pick him, I would choose him to stay on my care team! All of my (GISTs) Cardiologist, Urologist, Nephrologist and even my Dentist all have my well-being at HEART ?
Dr. Ryan is the best, he diagnosed my problems and answered all my questions regarding my problems. He has helped me throughout the years that I have been seeing him with referrals to other doctors at the University Hospital for other non-related illnesses.

Always caring and takes my concerns seriously.
Dr. Ryan was very caring and personable. He asked lots questions concerning my condition until he felt he understood the situation. He welcomed comments from my daughter, who had insight into my situation.
He was attentive to me and didn't seemed rushed. I was his most important person for that time. He explained things in terms I could understand and said my questions were good ones. He helped empower me to better take care of myself and health. Took awhile to get an appointment but definitely worth the wait

Appreciated the time Dr. Ryan spent with me despite the crush of Covid patients.
John Ryan is a wonderful doc. He is efficient, yet listens and answers patient questions well. I better understand a condition that I've had for some time and until now wasn't aware of the why. We're very fortunate that he is here. He also seems to run his team of PA and MAs very well.

If is my opinion Dr. Ryan is "A TOP DOC" and one of the best. I appreciate all that he is and does.

Thorough as can be. Asked pertinent questions. Listened to every word I said. Discussed concerns in detail. Told me what was important and what was not.

He's my favorite doctor

Excellent physician who gives amazing care.
I felt very grateful to be in his care
Dr. Ryan treats patients with respect and courtesy! He listens, and explains things carefully so the patient can clearly understand! I would highly recommend Dr Ryan!
It can be extremely difficult to find a cardiologist who is knowledgeable about my condition (INOCA-MVD with spasms specifically). Dr Ryan is up on all the latest research and doesn't try to question a diagnosis made decades ago. This is a huge relief. It is much easier to trust his opinion knowing that he has a good understanding of how the condition has been treated in the past, what's new, and where the research is headed.
He went over my current test result and the treatment I was receiving to which I could understand
What a truly swell guy...
I am very lucky to be treated by such a fine Doctor.
Dr Ryan is an amazing and caring physician. He is extremely knowledgeable and makes a point of knowing his patients.

I just love him! He gained my confidence immediately. I really liked the way he talked about Google searches and stated: "you are not going to die in 1 to 3 years." Such a great man and fabulous doctor. Can I say enough about this man/doctor?
good
Phenomenal team and team leader.
Dr. Ryan explained what he found from the test and added an addition inhaler stating he felt that I was possibly be off the oxygen during the day and only use it at night.

Dr Ryan is Top notch! The best and I recommend him to everyone.
Dr. Ryan has such an excellent bedside manner, with a quick sense of humor, which really made my dear Mama feel so much better! She was very nervous to go to her appointment, and he made her SMILE!
