I bought a Groupon for a brazilian wax and scheduled an appointment with Courtenay based mostly on the amount of awesome yelp reviews she had.
I've been waxed a few times before, but I felt that she did the most thorough job in removing all of the hair. She was also very knowledgeable in answering questions I had and I can tell she knows her stuff :)
I liked her personality, she was professional but kept things light and has a good sense of humor which anyone who is in that position can appreciate. I definitely plan on coming back.
Others have mentioned this, but I liked the online scheduling feature and also appreciated that I didn't have to wait weeks or months to get in to use my Groupon. It was a very positive experience.
