Many have tried cheaper alternatives, only to be left unprepared. Here’s what makes the CNTC experience different — and what every CNTC student gets out of the gate:

Most schools cash your check and forget your name. CNTC is built for the long haul — we train you, we launch you, and we’re still here on year five when you need a lien filed or a $200k claim reviewed.

Real students. Real classes. Real expertise. Every CNTC course is held in person in Rosemont, IL with a Zoom option available. Our instructors are directly invested in your success and helping you realize your professional goals.
