This work is a passion. It’s like playing baseball at age 50. You do it because it’s fun.

John Scheffey, PE



Since he was a boy playing sports, John has always had a passion for leading and developing teams. He believes a great team consists of people who aren’t afraid to try anything–what he considers “multi-sport athletes.” His philosophy even inspired our mission statement:  “To bring an athletic and multi-disciplined approach to the built environment.”


John’s early career working in construction management for Hess, and as an engineer for Sunoco, motivated him to start his own company. He saw the need for a single firm that could provide everything companies need to design and build their presence anywhere in the U.S.–a “one-stop shop.” So in 1999 he started Core States, originally serving clients in four states, augmenting the firm year after year with more and more service offerings. Eventually, John’s idea grew into what Core States is today–15 offices throughout the country, serving brands large and small across North America and beyond.


When John isn’t working, he enjoys traveling with his family, playing and watching sports, and serving the community. He loves to spend time with his employees outside the workplace. He hosts an annual Core States softball tournament, and also volunteers with his employees, serving the non-profit organizations of their choice. Some of the organizations John is personally passionate about are the March of Dimes, One House at a Time in Philadelphia, and the Boys and Girl’s Club.


  • Guilty pleasure: Grey Goose martini
  • Most interesting place he’s visited: The Ngorongoro Crater and the Serengeti, in Tanzania
  • Most irrational fear: Not being able to be athletic (though he has made peace with never dunking a basketball again)
