Dr. Liseane Koga, D.D.S./M.S.

Owner & Operator

Dr. Lis has been passionate about beautiful smiles since she was a teenager, and she has always been amazed how beautiful smiles can have a positive and lasting effect on someone’s life.

When she is not working, she likes to spend time with her husband and her dog. They love traveling all over the world, visiting different places, talking to people and being in touch with different cultures. Dr. Lis began backpacking South America when she was 15 year old, and her enthusiasm for visiting new places has never stopped. She and her husband also enjoy trying new restaurants—it’s their special thing.
