Diane Matsumoto, M.D. | Board Certified Pediatrician

Dr. Matsumoto trained at Washington University Medical School, consistently rated as one of the Top 10 medical schools in the country. She is the recipient of the Elizabeth Demonchaux Award in pediatrics. After serving children with complex medical needs at St. Louis Children's Hospital, she and her family moved to Phoenix in 1996.

Dr. Matsumoto spent the next 8 years as senior partner in a large medical practice. In 2004, she founded  TLC Pediatrics and fulfilled her dream of practicing in a small, intimate setting where patient care comes first. Over the years she has seen the practice grow enormously with the same passion that started it all. 


Dr. Matsumoto has been recognized by Phoenix Magazine as a “Top Doc.” Dr. Matsumoto is married to ophthalmologist Dr. Bert Matsumoto. They have 6 children.

"I'm a physician, so I'm probably more tough to deal with than some. Dr Matsumoto is the absolute BEST!! We are so blessed to have found such a great doc."  -Imani W.
