Learn From the Best: Meet Your Instructors

We exist for one reason: to educate. And we couldn’t do that the level that we do without our world-class instructors. They’re the backbone of our mission and the reason we’ve gained a reputation as America’s number one provider of education in the chimney and venting industry.

These dedicated individuals are committed to the betterment of the industry, and they take time away from their own chimney and venting companies to give back. We’re so glad that they do, because they make it possible for us to bring our students the leading education they want and deserve. When you learn from the best, you can become one of the best.
