I purchased a Groupon for this studio a few months ago and have been calling periodically for months and no body has answered the phone or returned a voicemail. I contacted Groupon and unfortunately this is non refundable, but they offered to contact them. I tried calling one more time, still no luck. At this point there is no point of wasting groupons time, because they will likely not get an answer either. I do not want to send a child to an establishment that I cannot get ahold of. To me this is a direct reflection of their service provided. I will be taking my business to another studio.
