I bought 3 treatments on Groupon and paid a little extra when I was there for the super whitening. I have had 2 visits with one left and I can't remember the last time my teeth were this white. I am so happy with the results. The staff is great. Very friendly and personable. Before your first treatment they explain everything in detail and are very patient with every question. While your getting the treatment they are constantly checking on you and making sure your comfortable and they keep moisturizing your lips so they don't dry out. I suggest you give this wonderful place a try.
