We've been taking our daughters to Dr. Bui, Dr. Kim, Dr. Kornu, and Dr. Lee for the past 7 years. They are truly the best! We've been so impressed with their care and we are so grateful to know such an incredible, smart, and compassionate team of pediatricians. Dr. Kim is our primary pediatrician and we see Dr. Bui, Dr. Kornu, and Dr. Lee as well!  They always listen patiently to our concerns, they are always happy to answer our questions, and they truly care about our daughters. They are very thorough in their care, and I really appreciate their expert advice and reassurance. I am comforted knowing that my daughers are in such great hands, and I've wholeheartedly recommended this wonderful team of pediatricians to many of my fellow parent friends!

The doctors at Sunshine Pediatrics have been caring for our four children for almost a decade, and their deep commitment to excellent patient care continues to impress us. They combine great medical knowledge with a warm and compassionate manner. My kids trust them completely and even look forward to their check-ups. We feel incredibly fortunate to have had these amazing doctors guide our children's health from infancy through their teenage years, and would wholeheartedly recommend them to any family seeking a pediatrician who truly cares.

The word "sunshine" perfectly describes the doctors at this practice. They consistently provide me with encouraging support, show genuine care for my boys as if they were family, and never dismiss my concerns. Having doctors like them is one of the best things in my life for sure!

Dr. Bui has been an outstanding pediatrician for both of my sons- a newborn and a toddler. She is incredibly accurate and thorough, and on more than one occasion has correctly diagnosed ailments that others couldn't, giving us answers and peace of mind when we needed it most. 


She genuinely loves children, and it shows in the way she cares for her patients. Her calm, compassionate approach puts both kids and parents at ease, and she always takes the time to listen carefully and explain things clearly without ever making us feel rushed. We feel incredibly grateful to have a pediatrician we trust completely- I only wish she could be my doctor too! I hightly recommend Dr. Bui to any family looking for knowledgeable, thoughtful, and dependable care.

Dr. Sandy Lee is the physician for three of my children. I am a physician myself and can't recommend her any more highly. She takes the extra time to address parent concerns and does a thorough explanation and appropriate workup. She is compassionate and dedicated to her field and never once have I felt rushed in our visits. It is evident that she is very knowledgeable and experienced and trust my own children to her care.

Dr. Bui is an exceptional pediatrician. She is both knowledgeable and personable, and she always takes the time to listen to our concerns without ever making us feel rushed. We truly appreciate how thoughtful and thorough she is during every visit. The entire team at Sunshine Pediatrics is wonderful, and the office itself is clean, bright, and conveniently located in Irvine. It creates a welcoming environment for both parents and children. We always leave feeling well cared for and confident that our kids are in great hands. Highly recommend Dr. Bui and Sunshine Pediatrics to any family looking for outstanding pediatric care!

I've spent years searching for a pediatrician who provides the level of attention, compassion, and follow-up that Dr. Lee does, and I'm so grateful we found her. When my son became very sick and we couldn't figure out what was causing it, Dr. Lee was thorough, open-minded, and willing to run the appropriate tests instead of taking a wait-and-see approach. She identified the cause quickly, started treatment right away, and my son improved almost immediately. What impressed me even more was her follow-up. She personally called us almost every other day to check on my son and make sure he was continuing to improve until we were on a clear path to recovery. In the 11 years I've been a parent, I've never experienced this level of care from a pediatrician. It honestly feels more like a concierge practice than a traditional pediatric office. The entire team at Sunshine Pediatrics has been wonderful, and the office itself is beautiful, modern, and exceptionally clean. I wholeheartedly recommend Dr. Lee and Sunshine Pediatrics to any parent looking for a pediatrician who truly goes above and beyond.
