Dr. Liu and his staff make going to the dentist easy and stress free. I've never had much of an "issue" with visiting the dentist; however I am new to Arizona and had to find all new doctors. I knew from my first visit that I wasn't going to have to find another dentist. After my first cleaning, I had to do a follow up to fill a cavity. It was so painless and easy, I even fell asleep a few times throughout the process. I'd recommend Dr. Liu to anyone who needs a new dentist in the Phoenix, Scottsdale or Tempe area.
