Behind in technology. They don't even have a software that can print receipts. The receptionist handwrites on those little slips from receipt books you can get at Office Depot for less than $20.
Terrible customer service. Every time I called, I would get their voicemail. What kind of a business doesn't have a live person answering the phone during peak business hours? I can understand if they have a fixed lunch hour or if it's after hours.
They kept rescheduling on me. I had to keep adjusting my time off request at work due to their rescheduling. One day the receptionist called me to cancel my appointment because "Dr. Yu is doing something on that day and he will be closing the office". I asked when the next available date was, and it was over a month later.
So I got smart and transferred. I'm happy with my new dentist and the office staff.
