Aaron Stull

Aaron Stull is a second-generation foundation repair professional who learned the craft the right way—from the ground up. As a young man, he worked alongside his father in the field, mastering every role from laborer to foreman to operational leadership before the age of 18. When his father sold the family business in 2001, Aaron chose to forge his own path.

In 2003, he founded Keystone Basement Systems, now widely regarded as western Pennsylvania’s leading foundation repair firm. With a disciplined management team and a commitment to excellence, Keystone has become the most reviewed and highest-rated company in its sector.

Aaron leads with clarity, precision, and purpose. His role centers on removing obstacles, refining systems, setting direction, and recruiting exceptional people who align with the company’s mission and values.

“I’m Aaron, President of Keystone Basement Systems. My responsibility is to ensure we stay aligned with our vision while continuing to raise the bar in our industry.”

Outside of work, Aaron is a lifelong student of strategy, history, psychology, and leadership—drawing insight from across disciplines to guide his thinking and sharpen his approach. He enjoys time with his family, hunting, and the enduring challenge of a well-played game of chess.
