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.

Dr. Miyamoto was the consummate, professional doctor. He took his time asking my son questions, listened carefully to his responses, and did a complete check up. I feel very strongly that his physical is more in depth than a lot of other pediatricians might perform.

April 26, 2018
I was so please with my Dr visit I booked another appointment with Dr Miyamoto for my son's physical. I had a great experience!
April 23, 2018
I would recommend Dr. Miyamoto and his staff to all parents. I would suggest they start with all newborn children. He is so thorough and would never dismiss or disregard any worries or concerns. He really takes the time to get to know all of his young patients individually. The hardest thing about him is having to leave him when your kids turn 21. He’s a hard act to follow. Finding a primary doctor after him seems almost impossible. Nothing means more to parents than their children’s health. I feel blessed that I’ve had someone like him to help me watch over them and to know they were in the best hands possible. Truly, the best doctor I have ever known.
April 23, 2018
