I really enjoy all the instructors. They try to make all of the classes enjoyable. Yes the classes may be 8 hours long, but they are very informative and worth taking. The customer service is awesome, they are willing to help you any way they can and try to give you all the information you will need to be fully informed. They all seemed to go above and beyond. I think it is really awesome too that they have complimentary coffee, tea, hot chocolate and even some candy to snack on. For bigger snacks, they had the vending machine or even KFC next store.
