Dr. Liu and his staff are absolutely awesome. The office is full of friendly, honest and professional people. Dr. Liu is very thorough and knows what he’s doing. The hygienist is very sweet and caring — she works gently and continuously makes sure that you are okay during the cleaning. Lorraine(office manager) is very efficient and ensures that you understand all insurance and financial information clearly. I have been a patient for 2 years and I highly recommend them.
