Our mission is simple: bring clarity, confidence, and control to your business decisions. Through hands-on financial management, bookkeeping, and fractional C-level guidance, we help you navigate growth, scale with intention, and stay ahead of the curve.

Who we are

At StrongSage Advisors, we bridge the gap between small-business grit and corporate-level strategy. We believe every growing business deserves access to seasoned financial and operational leadership—without the cost or complexity of hiring full-time executives.

Our Mission

Growth doesn’t happen by accident—it’s engineered through insight, structure, and agility. We combine corporate-level discipline with the adaptability that small and mid-sized businesses need to compete and thrive.

Our Philosophy

David Schieffer is the founder and executive advisor of StrongSage, bringing over 20 years of experience leading initiatives for Fortune 500 organizations in finance, technology, operations, and strategy.

After two decades in corporate advisory roles, David recognized that smaller businesses face the same complex challenges—without access to the same caliber of expertise. He founded StrongSage to bring enterprise-level insight, systems, and structure to the small and mid-market space.

David’s leadership philosophy is built on clarity, integrity, and execution. He believes that when business leaders align financial discipline, operational efficiency, and strategic focus, they unlock scalable, sustainable growth.

Based in the Kansas City area, David is also deeply involved in his local community and remains a strong advocate for small-business development and entrepreneurship.
