I'm not even sure how to rate this office. I would give Dr. Liu 5 stars but his office staff gets zero. I was a patient of Dr. Liu's for many years and he delivered my baby in 2009. Then, several years ago, something in his office management and/or staffing changed. They stopped sending me postcards when it was time for my annual check-up. I called several times to try and find out if it was time come in for a visit and nobody would return my calls. I finally had to find a new doctor.
