I also have been a pt there at overlake dental and have been rescheduled. They called and were very apologetic and did their best to get me back in. I truly believe and know that there must have a very important reason for the reschedule. Everyone has priority's and sometimes they come before work and until I find out the reschedule appointment was because the Dr. felt like going bowling or something instead of working then I put all my trust in the fact that it must be something absolutely necessary. If you have met Dr. Smith and get to know him I know you will see that he is the best Dentist you will ever find. even if there is an appointment that has to be changed or rescheduled just remember that he as a dentist is worth going to , despite the fact that he may have a priority that needs his attention(everyone has priority's over work) . He is by far worth the possibility of a rescheduled appointment. If that is a persons chief complaint and feels like writing a bad review because of it, then your not worthy of being his pt.
