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.

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

PIH within the last couple of years has become a more reliable and responsive provider of medical services for my children, with physicians more concerned than before about the health and well being of my kids. The office upgrades, physical environment and electronic processes, make you feel you are getting a more first class experience.
