Dr. Bjornsen completed his pediatric training at Phoenix Children's Hospital/Maricopa Medical Center Pediatric Residency Program. There, he learned to appreciate every aspect of pediatric care.

During his time in Houston, he cared for a wide range of populations, including young recreational athletes all the way to Division 1 collegiate athletes.Perhaps spurred by a way too close experience with Hurricane Harvey, the Bjornsens decided to come back to the Valley in 2018 where he has practiced both general pediatrics and pediatric sports medicine.
