I passed the Concrete class, followed by the Brick class, and then the Roofing (Unlimited) class. The instructors are amazing and incredibly helpful. They genuinely care about your success and make sure you’re fully prepared.

RoofingMasonry

I took classes for two separate licenses, roofing and masonry, and the instructors are incredibly knowledgeable and engaging. If you need to get your contractor’s license in Illinois, this is the place to go. Worth every penny!

I have attended twice. First for the Roofing license, and now for the Public Adjuster license. Both instructors have been amazing and patient! I will definitely be going back to complete other certificates!

Public Adjuster

The Public Adjuster class helped me understand so much about the insurance and restoration industry. I’m excited to take what I’ve learned into this next chapter of my roofing journey. Highly recommend to anyone looking to create new opportunities.

Public AdjusterXactimate

I completed their advanced public adjusting course, then their Xactimate training, which increased the value of my claims by 20 to 70%. Both courses were excellent investments, fully justifying every penny.

Public Adjuster

Can’t express enough how helpful the PA Class is. They go through everything thoroughly and keep it interactive. As someone brand new to all of this, I learned a lot in just a few short days, and then they give you a bunch of tools to take home and study.

I’m a second-time student. I want to personally thank Bozena for always going above and beyond to help me! She helped me register and kept me informed throughout the entire process.

Licensing Support

Awesome people. Even after the class is over and you’ve passed the test, they are more than willing to help and answer any questions with the applications and forms needed for the state licensing.
