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. Married for over 30 years, the father of three stays active with golf, running, skiing and mountain biking and belongs to ChildD, a nonprofit organization that provides resources to students with learning disabilities.

Doctor Miyamoto has been my son's doctor since he was a baby. Now he is the doctor for both of my sons. Doctor Miyamoto is very respectful, kind, and always takes his time to explain everything. In addition, he always regards the feelings of his patients and is always open for questions or comments. Both of my sons are very happy to go to their doctors appointments.

Dr. Miyamoto has always been a kind and empathetic doctor who listens to what his patients and parents say. He responds in a way that shows his genuine concern and is also easy to understand. Occassionally, he will use terms we are not familiar with, but he always explains what we don't understand. Dr. Miyamoto was recommended to me 19 years ago and I have continued to recommend him throughout this time.
