I also went here, like many of the reviewers before, for the groupon last year. I must say, they are consistent with their attitudes and answering phones. I tried making appointments 5 times with calls unanswered then they were not flexible at all with scheduling for groupon customers and we were running out of time! There are many places in the area that do a better job with a better attitude. Don't waste your time here.
This should have posted 7/2011. These problems may have been addressed/fixed. However I would never buy a groupon/deal for this place.
