Partners, Stefan LeRow, Rick Tullis, Brian Aynesworth, and Will Fair founded Capstone in 2005. They wanted to start a company that not only served the community with its talents but also was a company where talented, hardworking employees could flourish and succeed. They believed that a company built around a servant leadership culture would attract the best employee talent and deliver the best products and services to its customers. To that end, Capstone now has over 200 team members serving the community with each of their unique skills.


Servant-Leadership is a practical philosophy that supports people who choose to serve first, and then lead as a way of expanding service to individuals and institutions. Servant-leaders may or may not hold formal leadership positions. Servant-leadership encourages collaboration, trust, foresight, listening, and the ethical use of power and empowerment. It is this leadership that creates a team environment at Capstone, and enables us to provide solutions at the lowest possible cost and within the highest possible quality for our customer.
