About Us

John Iltis


Over the past 20 years, John has built one of the most complete and successful companies in the area. John learned the trade working for a local builder and soon became inspired to found his own company. Iltis Construction has become synonymous with the highest quality and workmanship as well as one of the easiest building companies to work with.


John takes pride in every project like it is his own. From large condos, apartments, and upscale homes to minor renovations, the results speak for themselves.

Matthew Kozuch

Project Coordinator

Matt was on construction sites at an early age with his grandfather (W.A. Kozuch Builders) who made his name in Midland, MI building many of the distinctive Frank Lloyd Wright inspired Alden Dow designs. Having worked on his own, and for several builders in the Big Rapids area, Matt built a reputation as a people person with an attention to detail.


It's these traits that made him a good choice to help our company grow with better customer service and a more efficient building experience. Matt will be there to guide you during the building process, all the way to the end.
