He is very thorough, professional, follows up and responds to my written communications promptly. He takes his time to answers questions without rushing me out the door. The front staff is very pleasant, and appointments are easy to make. I vet all my doctors as I was in the healthcare field. Dr. Miyamoto is one that I can trust with my heart!

Let me start this review by saying that I am a retired ER/OR RN and am particular whom I trust w my…read morehealth care, Dr. Miyamoto was the THIRD cardiologist I consulted w. He and his staff gave me exemplary care, and I am glad I followed my intuition, pursuing answers to what didn't seem correct to me w the other two cardiologists. I highly recommend Dr. Miyamoto. It is impossible to overstate the excellence of the care I received from him and his staff. Initially, I requested a Calcium Score Test bc of family history. The results were concerning - a thoracic aneurysm and I consulted w a cardiologist affiliated w St. Jude who ordered an echocardiogram, which was carried out at St. Jude. The results were inconclusive (I later learned) due to the tech not knowing alternate probe placement for my anatomy. The cardiologist at St. Jude was not helpful and really lacking in communication skills. I have later learned the EKG leads were likely placed incorrectly and possible old MI was not addressed in the consult- I read about in MyChart and had to send a message first before I received very unsatisfactory answers - from a Medical Assistant! I guess the cardiologist there couldn't be bothered!! All my communication w Dr. Miyamoto was w him directly. I really appreciated that. When the inconclusive results came in from the echo, I asked for alternative tests and never got a satisfactory answer from Cardiologist 1. I was told to do a stress test, which given the aneurysm diagnosis, I was uncomfortable w. I saw a second cardiologist who spent considerable time w me in my appointment and was a remarkably kind, great communicator, but I felt I still didn't have answers. Finally, I saw Dr. Miyamoto, and I am so grateful I did. He ordered the Cardiac MRI, which Mission Hospital scheduled within a few days time. The results were posted on MyChart the night before a holiday. No aneurysm was detected and the exam was essentially normal!! The next day was a holiday (office was closed) yet I received a message from Dr Miyamoto that my report was "very good" and that I could "follow up w my PCP" and didn't need the stress test or further cardiology work up but could return for care if needed. My message is if something seems unsatisfactory or just doesn't feel right w a doctor, seek further consults until you are comfortable w the provider. It is our own health that we have to guard and advocate for.

I am a new patient of Dr Desai. I really like him, and his office staff…read more My first appointment I received a call that Dr Desai was held over at the hospital and could I reschedule. They then called me back that he could actually make it so I rushed over. They made copies of all paperwork I brought them, including a huge report from a 24 hour holter monitor. They do not validate parking however that day they did for me, which I thought was so nice. I had an EKG done and then spoke with Dr Desai to go over why I was there. He said he had my paperwork but wanted to hear from me. I liked that - a doctor who listens and communicates is a great quality. He put in for three tests for me which I had completed today, in the suite right next to their office. Echo Cardiogram, Treadmill Stress Test and then have a week long heart monitor put on. I had to reschedule the heart monitor due to reasons on my end. I was in the office for about 2 1/2 hours today and I had different people for each test. Everyone was so incredibly nice and efficient. I sat between tests for about an hour in the ladies waiting room. It was freezing and it felt so good. They did leave me a blanket however I didn't use it. I always run hot so the cold air felt so good. The Echo Cardiogram was uncomfortable at times but easy. The Treadmill Stress Test sucked. I didn't last long lol. I did try to talk through most of it however realized I needed to shut up at one point and just get through it. They take your blood pressure every couple minutes and you can see the screen with your heart rate. I got a really horrible pain so I think it was ended a bit quicker than maybe usual. You have to continue to sit afterward to monitor your blood pressure still every couple minutes until it goes back to normal and until your heart rate goes back under 100. While I don't want to do that again any time soon (haha) they were so nice and accommodating and comforting. Great staff. Everything about Dr Desai, his staff, and the staff in the testing suite are amazing. I just found out today I don't think he's covered on my insurance that is changing 9/1 and I am REALLY upset about it. It's hard to find such a great practice so we'll see what happens. They are located in the medical building on the corner, UNDER Mission Hospital - NOT the same lot as the hospital. Also, as a reminder, they do not validate parking and parking is NO CASH.
