Hi, this is a message for Ms. Helen Kim. Ms. Kim, this is your dentist office calling to remind about your appoitment with Dr. White on Thursday at 11 a.m. I can see my appoitment book that you are scheduled for cleaning that day. Anyway, I'd like to remind you at this time that you need to arrive at least 10 minutes early to fill out some information. If by any chance you cannot make it to your appointment, please let us know at least two hours before your appointment. Have a nice day and we will see you this Thursday.
