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 29 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.

Th me office staff is great. Unfortunately, the doctor did not have a good personality for kids, he was very dry and didn't engage with the patient or patient's family. He seemed like he was bothered.
