Jeffrey R. Hershberger

Founder/Managing Owner of Slick Timberworks

Mr. Hershberger began his construction and engineering career when he found a job as a timber frame carpenter after returning east broke and jobless from a winter chasing snow in Jackson Hole. This job of convenience led to over a decade of making sawdust, first as joiner than as itinerate timber framer and small business owner. This career path ignited a passion for woodworking and the pursuit of the historic craft. It was initially fostered by climbing around the bank barn of his childhood home in Bucks County, Pennsylvania. A recession and a baby boy led to the decision to return to school to study civil engineering, broadening his understanding of structural analysis and material science.

Upon graduating Mr. Hershberger headed back to the building industry, first as a subcontracted drafter and engineering intern, then structural engineering project manager. After a handful of years of consulting engineering work for log and timber manufacturers throughout North America the draw to return back to the shop floor became too much to ignore, and lead to the creation of Slick Timberworks in the summer of 2020, an effort to bring a bit more flexibility between structural engineering consulting and timber fabrication. He relies heavily on his practical experience while working with clients to produce structurally efficient and elegant designs, and while remaining focused on the initial priorities of the project. Mr. Hershberger has earned a B.S. degree in Geology from Bates College and a B.S. degree in Civil Engineering from the University of North Dakota.
