Terrible service!!!! They believe they have the right to dispose of my time when they call you at 2 in the afternoon and spend 40 minutes without even appointing any person or doctor or dental ... I just go and they will charge me because I "cancel the appointment" when One shows up but they are the ones who do not feel like not attending to you ... I wonder why I quote many people if they are going to be in a lunch or doing I don't know what ... lousy attention ... hopefully the 20 Dollars that they charge serve them for more training or something
