Dr. Miyamoto became inspired to pursue pediatric medicine after a cousin died of leukemia at age seven. “I love children. They make me laugh and smile,” comments Dr. Miyamoto who enjoys “caring for the wide range of diseases and health issues” and cherishes the relationships he’s established with parents and families. A native of Arcadia, Dr. Miyamoto played water polo, basketball and swam in high school.

Great service, great doctors. Keep it up.

Dr Miyamoto is always fantastic and always so kind and seems so caring. The nurse we typically see is also amazing and fantastic and seems so empathetic. I'm disappointed to say that the nurse who attended by baby this last visit seemed annoyed and spoke to me curtly. I hope this feedback will assist in aiding this individual to reflect on their tone with patients, as I myself work in a hospital, I am required to do the same.

We were seen an hour past our scheduled appointment time. Understandable that people have needs that may require additional time.

I love the staff and the providers in this office, but I have noticed that there is no enforcement of mask mandates and no screening of patients before they come in the building or even in the waiting room. There were parents in the waiting room without masks on and I have noticed this is a trend in recent weeks, so it is concerning to me.

We love Dr. Miyamoto! He always takes the time to listen to our concerns and offer recommendations or advice. We also love that they give the children a book and a balloon for each visit. That is very thoughtful! Thank you for all you do Dr. Miyamoto and his staff!

We waited one hour for the doctor to see us. I would never show up one hour late to a doctor appointment and we did not appreciate having to wait that long. It was not fair to us.

Hey was only one working elevator. That's elevators are frequently broken. They're under repair service not too sure exactly what but elevators are huge there. Have the stairs more accessible to people to take stairs up and down. Also, there was a lot of lag time between the nurse and the doctor, and the doctor and the nurse coming. Back to give vaccine too much lag time. Thank you.

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'm very happy with the provider. He's an amazing doctor, great staff. The only thing is, once you guys moved into the automated appointment system, I haven't really been able to communicate or get an appointment on time. So I wish you would go back to the way it was.
