Meet the Doctor


Kathy Tomasu, DDS

I grew up in Hawaii Kai and graduated from Kaiser High School.  I then attended UH Manoa for undergrad and graduated from the University of Washington, School of Dentistry.  Growing up, I wanted to be a pilot, a veterinarian, a teacher, a lawyer, an Olympic gymnast or figure skater, an author, a movie star, just to name a few.  Somehow I found my way to dentistry and couldn’t think of anything else I’d rather be doing.  I love dentistry because of the great patients that I get to serve and my incredible team whom I consider my second family.  Our philosophy is based on customer service and to treat our patients as we would like our own family to be treated.  

In my spare time, I like to golf with my husband and play with our 2 four-legged kids, Pono, and Cookie.


Jason Kamezawa, DDS

Native to Hawaii Kai, Jason attended to school with Kathy.  He did his undergrad at Washington State and later following in his father's footsteps graduating with a dental degree from Boston University.  He works out to eat, and during his spare time, he enjoys hanging out with his only daughter.

Keith Dung, DDS

Born and raised in Honolulu, Keith attended St. Louis High School and later moved on to UH Manoa, where he met Kathy at the Pre-Dental Club.  He graduated from the University of Washington School of Dentistry in Seattle, and lived there for 22 years before moving back home to Honolulu in November of 2009.  He enjoys watching football and his favorite team is the Pittsburg Steelers.
