Jason Tsai

Doctor of Medicine in Dentistry

Providing exceptional, comprehensive oral health care with a personal touch is Dr. Jason Tsai’s goal at Complete Family Dentistry. Dr. Tsai’s dental training has spanned the country, from prerequisites at the University of Washington (Seattle, WA) to dental school at the Rutgers School of Dental Medicine (Newark, NJ) to an additional year of residency training at Wichita State University’s AEGD program (Wichita, KS). Dr. Tsai is a self-proclaimed “continuing education junkie” who loves to update his dental skills and knowledge by attending courses from world-renowned educators.

Dr. Tsai’s better half is Colleen, who was raised in Shoreline, WA and who also works in healthcare. They are blessed with a bouncing baby boy named Nicholas and a goofy Golden-doodle named Totoro. The Tsai family loves exploring Bellevue and the surrounding region for good eats, hikes and dog parks. Dr. Tsai, meanwhile, loves spending time with family, working out, reading, podcasts, and trying to maintain a respectable golf handicap.

Dr. Tsai looks forward to taking care of you and your oral health needs!
