I believe "words of mouth". Having visited Dr. Ku for over 7 years and still couldn't fixed my dental problem? They treated me neither courteous nor professional. He is the most expensive dentist I've ever known. All they care is making sure to collect their money before providing any services and it doesn't matter how long you have been a patient there. Only money matters! I had problems with the bridge which was replaced for less than two years. They had to charge me again with regular price in order to get another one replaced. He couldn't explain why the existing one was cracked. Most of the dentists would replace it for free as long as it's within 5 years. He is not only lack of ethics but also unprofessional as a dentist.
It was a nightmare. Thanks to him that I'm able to find a true professional who is not only very knowledgable but also understanding and less expensive.
