I took the 11 week classes. I always got the help that I needed to learn the materials. It is very fast paced at first but it levels off. It helps that everything is very well organized and classmates can help one another.

Good materail content – slides and presentations were easy to understand and well organized. Group breakout option as well as the choice to go through lunch made it quick and efficient. I learned a lot and was ready to bring it back to my boss at work.

My instructors were very helpful. I normally work up front but the doctor wanted me to help with x-rays. I appreciate how I wasn’t just thrown into it – I got lots of extra attention because I have never done them before. Everyone was very helpful.
