Tiffany Wiguna, MD
Dr. Wiguna was born and raised in sunny Southern California, graduated from UCLA and got her medical degree studying International Health at Ben Gurion University in Israel. She then returned to complete her pediatrics residency at Harbor UCLA Medical Center in Torrance.
She is passionate about encouraging children and families to pursue healthy living through nutrition and physical activity, helping children get control of their asthma and eczema, and having 'real talk' with fellow parents and their kids. It's her goal to help families feel heard, supported, cared for, and at ease during her appointments.
Her proudest accomplishment is being a mom to her daughter Maui (and hopefully more kids in the future!). She loves doing yoga, cooking, singing, and going to Disneyland with her family. She and her husband, Dr. Jason Wiguna, love being parents first and doctors second, and spend their free time in family jam sessions, being active together, and with their church family.
