Dr. Miyamoto is an extremely caring doctor. My kids trust him. They love him. They are both very excited when they go see. Dr. Miyamoto. We could not be any happier, my husband, and I, for the care that he gives our kids. The trust that we have instilled in him in the past, almost 6 years, and it's a huge blessing that when we tell our kids, they have to go to the doctor, they don't cry. Instead they get excited, and that is a testimony to what kind of doctor, Dr. Miyamoto is.

I appreciate having the same provider & having the same doctor since birth. It's very comforting. However, I don't feel like I have the friendliest conversations with all the employees. I understand we are living in negative and uncertain times, but kindness goes a long way these days. And in my ideal world, I want quality friendly conversations with the nurses during my visits.

Dr. Miyamoto was informative, helpful and even humored my daughter by asking about my eye. She was concerned about a blood vessel that burst. It looked a lot worse than it was. It made her feel better and I appreciated that he remembered because she asked him at the beginning of the appt. at the very end he asked about my eye without being reminded. Thank you ??

Dr. Miyamoto is absolutely amazing! He went above and beyond and ensured my son was well taken care of. Dr. Miyamoto referred my son to CHOC, who later was diagnosed with Leukemia. Despite being under CHOC's care now, Dr. Miyamoto continued to check in on us after we learned of our son's diagnosis and took the time to answer our questions and listened to our concerns and gave us hope and encouragement.
