I live in the Lehigh Valley and I have never heard of them. The website looks shady to me. I clicked on the classes tab and it says, "We are currently working on our class schedule for the Spring & Summer of 2016.
I thought it was a little sketchy too. I tried pulling up their BBB rating, etc. to no avail. I found two different addresses for them too. That's why I asked here, I figured someone would know something about them.
