Dr. Ku might be one of the worst dentists out there. His office and equipment is completely outdated and he does not care about your teeth at all- he will try to sell you on every single service they offer with money-hungry eyes. Be prepared for a lot of PAIN during a simple cleaning. The only pro thing I can really say is that he is cheap- cleaning was $50 and xrays were $50. But you will get what you paid for...I will never go back again.
