Jack Witte


As president and owner of Corrective Asphalt Materials, LLC, Jack holds overall responsibility for the sales and marketing of the business.
He began working at CAM in 2003 while he was earning his engineering degree. In 2005, he joined the company full time as a project engineer. Jack quickly assumed responsibility for sales and began to sell CAM and its suite of products on their technical merits. In 2013, Jack and two co-owners purchased CAM.

Over the years, Jack has built lasting relationships with the company’s growing customer base. He has worked hard to put together a team of technically savvy people who understand the market, the merits of road preservation and the range of options available to customers.

Jack earned his Bachelor of Science in Civil Engineering from the University of Missouri, Rolla, in 2005. He discovered his knack for sales when he joined the Sigma Tau Gamma fraternity and made it his mission to increase membership numbers.

Jack enjoys having a beer with his co-workers and taking a nap on Saturday afternoons. He likes hunting waterfowl and he loves boating with his wife and three young children on the Lake of the Ozarks.

Jack is an active member of the Entrepreneurs’ Organization (EO).
American Public Works Association (APWA).
Midwest Pavement Preservation Partnership (MPPP).

The Team

Marc Taillon

Vice President Engineering and Operations/Owner

Marc is responsible for all aspects of finance and engineering at Corrective Asphalt Materials. He enjoys the company’s fast-paced environment and is known for his ability to think through all the steps of a project and spot potential conflicts and other issues.

He works with his team to ensure that every customer gets the highest level of customer service. That means every member of the team keeps the customer’s needs at the forefront and is willing to work relentlessly to solve any problems.

Marc has a strong manufacturing and operations background. Before joining CAM, he worked at Sunnen Products Company, AGT Services and The Gund Company.

For hobbies, Marc enjoys all things mechanical. Whether it is a boat or a car, he likes nothing better than to take them apart and then put them back together. And that is an interest that extends to his work at CAM. If any of the company’s heavy equipment breaks down unexpectedly, rather than delay the job, Marc has rolled up his sleeves and done everything he can to get it working again.

Marc has a Bachelor of Science in Mechanical Engineering from the University of Missouri, Rolla and an Associates Degree from SUNY Morrisville.
