Stahl Sheaffer Engineering has been named a Top 100 Organization for 2025 by Pennsylvania Business Central! This marks our third consecutive year receiving this recognition for making a positive impact in Central PA communities.
A huge thank you to our team, clients, and partners who help make this possible!

Congratulations to John Weaver, Greg Wilhelm, Don Webb, Derek Sullivan, and Briette Yeater on their promotions! Your hard work, dedication, and expertise make a difference every day. Thank you for excelling at what you do and for contributing to the success of Stahl Sheaffer. We’re proud to have you on our team!

​Our Southpointe team has packed up the cubicles and is heading to a new space—just down the block in Canonsburg, PA! We will be settling in next week while handling business as usual. 

​We are happy to welcome back Mike Haynes to the Stahl Sheaffer team! Mike joins us with 21 years of engineering and project management experience in multiple disciplines, including land development, transportation, energy, and municipal. He also has worked with PennDOT 2-0, City of DuBois/Sandy Township, and has ran his own business in conjunction with working at Stahl Sheaffer. He will be part of our Site team in the Clearfield office.
