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.

The wait times are to long especially for little kids that can only sit still for short periods of time. I know not just my kids but everybody's children can't sit still for wait times of 45 minutes to an hour every single time we go in.

Dr. Miyamoto is an amazing pediatrician. Not only is he great with my children, but he is so thorough with the information and details that he gives to me as a parent that I always leave the office with confidence. His staff is so friendly and knowledgeable that they too make the entire experience extremely reassuring. I would never take my children any where else.

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.

Dr. Miyamoto is a fantastic physician. He is so patient and interactive with my son, and explains everything that he is doing during the check up so my son knows what is going on. He was extremely thorough in going over my child's development and offered great advice and tips to ensure that my son is progressing as he should. The nurses were also very friendly and attentive to my son and really made him feel comfortable. I love this office and know that every time I come that my son will receive the care and consideration that every parent hopes for.
