About Dr. Judith Lau

Dr. Judith Lau is thrilled to be the newest member of the Sierra Pacific Pediatrics Family. She is currently taking new patients at both our Fontana and Eastvale locations. Although she is Canadian by birth, Dr. Lau grew up in Temple City, California and attended the University of California, Irvine where she majored in biological sciences. She subsequently found her way back to winter seasons and more than 100 inches of snow per year when she studied at the Lake Erie College of Osteopathic Medicine in Pennsylvania.

After graduating from medical school, Dr. Lau completed her pediatric residency at the Children's Hospital of Michigan in Detroit from 2016 to 2019. In addition, she served a one year term as Chief Resident of her training program before joining Sierra Pacific Pediatrics in July of 2020. From well-child appointments to sick visits and everything in between, Dr. Lau’s passion for taking care of children shines through in her interactions with patients and families. She strives to be thorough and understanding to the needs of each child that comes through our doors. For annual physicals, Dr. Lau has a habit of asking her school-aged patients: “what do you want to be when you grow up?”. Whether it be an astronaut, ballerina, police officer, or an inventor of gadgets, etc. she’s always delighted to hear about each dream and aspiration. To Dr. Lau being a pediatrician means ensuring that each child is well-equipped to grow and thrive in life and that, to her, is the best job in the world!
