I also purchased a Groupon before reading the bad reviews, but I had a great experience. Even though they did not answer my first call, they returned my call within an hour and I was scheduled for the next week, the time that I needed.
Brittany was extremely nice and I did not feel embarrassed or intimidated. I got a lot of information and find it useful. She did offer me a package, but I politely refused and there was no pushing to buy it.
I recommend this place.
