Dr. Hayashi completed her medical degree at Drexel University College of Medicine and holds a master’s in public health in sociocultural diversity and health from the University of California, Irvine. She completed her pediatric residency at Children’s Hospital of Orange County, where she treated a wide array of patients with complex medical problems and worked with families from diverse backgrounds. She joined the practice in 2017. She believes proactive care from an early age gives kids the best chance of staying healthy. Toward this effort, she loves to teach and work with families to create the best environment for healthy living and growth. Building relationships with families based on trust and openness is very important to her, and she brings those qualities to her practice.
