We Teach Students How to Succeed
We teach students to succeed on Tests and In The Workplace.
Our mantra has always been to not only coach people on how to pass the test the first go around, but to teach them the intent of the code. Where most of our competitors teach you strictly how to pass the test. Our ideology is that once you do get your certification, you have a thorough understanding of the code's requirements and intent; therefore making you a more competent inspector.

The way I look at it, you are a reflection of us and I have no intent of being known as the one who helped Ned in the third grade attain their cert. With pulling the plug on the full time work, my intent was to go to the one, or two week classes and drop the evening classes. But based on the feedback from several of the classes and staying true to our mantra we will continue with the evening classes as it allows you time to get hit with new material, a day or two to shore up on it and then you get hit with some more. As the exceptional instructors will tell you, "You get out of the class what you put into it." If you are truly applying yourself - studying, reading, work the exercises you will pass any of the tests without an issue. Good Luck and keep on rocking towards your future!

You can call, e-mail, or swing by when you are in the area; we always enjoy talking to people on their career paths and coaching them in the right direction.
