Very unprofessional - This would have been the first time to whiten my teeth, however there was no one at the facility. I had an appointment for Sunday October 6, 2013 at 9 a.m., took me half an hour to get there, and which I did get there on time and the door was locked. I even waited for 15 minutes for an employee to arrive but no one came. I called and left a voice mail and email as well.
