I purchased a groupon to get my teeth whitened before my wedding from this office. I Madeleine first apt with no problems. When I got to the office the front desk lady proceeded to tell me that the groupon had really expired (although the expiration date on the actual groupon was not for 4-5 weeks!) and offered me an addition service for nearly $200. I pointed out the expiration date and after having me wait she said they would honor it. Three months after I used the groupon I get a bill in the mail that has no description-just says past due" for $115! Place is shady! Wouldn't recommend it!
