Team Work Makes The Dream Work

John Vajda served in the US Army and deployed to Iraq. After his military service, John spent several years in product design and construction management. He always had a desire to have his own business, and did occasional side jobs for friends and relatives, but coincidence brought him into Nate Bunty’s sphere of influence. 

Nate, a serial entrepreneur and “idea guy”, believed he could get a new construction company off the ground with his marketing know-how and entrepreneurial spirit – he just lacked technical construction knowledge. 

Together, John and Nate founded Exponential Construction with a focus on installing the highest quality fences in Lancaster County. The success of that operation allowed them to add additional services and begin trading as Exponential Construction – fulfilling a wider array of outdoor construction projects as well as coming inside the house to renovate Kitchens, Baths and Basements
