Our Management Team

John Inselmini


Hard work and attention to detail have always been important to John. He was raised that way and it carried over into his business model for Inselmini Construction Company.

Born in Latrobe, PA, John attended Clarion University and graduated with a degree in Business. John paired his natural abilities to build with his education to later found ICC in 1975.

The process of building is a long one and requires communication with the customer every step of the way. This key attention to detail, and over 40 years’ experience, makes ICC the company it is today. That knowledge is a valuable tool to the customer in making their decisions as they proceed through the project.
