Dr. Jack

Dr. Wai Chan is a pediatric dentist who goes by Dr. Jack around the office. He was born in Hong Kong and immigrated to the US when he was around 9. He spent the rest of his childhood growing up in the picturesque Adirondacks of upstate New York. After growing up and training in cold states, he is now here and hopes to establish his roots in sunny San Diego.
He attended Cornell University, where he completed his Bachelor's degree in Biological Sciences.

He then received his Doctorate of Dental Surgery at SUNY Stony Brook School of Dental Medicine where he not only got training in pediatric dentistry but also training in treating patients with special needs. After graduating from dental school, he went on to complete a year of general practice residency at SUNY Stony Brook School of Dental Medicine, where he received additional training on complex restoration for the adult population and an in-depth focus on the special needs population. He then practiced as a general dentist at a federally qualified health center in upstate New York to help deliver care to low-income individuals and discovered his passion for pediatric dentistry. Following the stint as a general dentist, he continued to seek further education in pediatric dentistry at the University of Minnesota, where he got additional training in treating the pediatric population and kids with special health care needs. He has since worked as a pediatric dentist in California.

Dr. Jack enjoys pediatric dentistry because it offers him a chance to interact with kids and make a difference in their oral health. He believes in creating individualized care for each child and their family. Having worked as a general dentist, He has seen the detrimental effects of a lack of education and lack of prevention on teeth. This effect can often carry on into adulthood and have permanent effects on adult teeth. He focuses on creating a positive experience and helping to build self-esteem in a dental setting while encouraging healthy oral habits.

Dr. Jack is excited to be working with the team at Little Star Pediatric Dentistry! When he isn’t practicing dentistry, he enjoys being outdoors or cooking recipes that he's tried in restaurants.
