Early Life & Education
Born on August 31, 1946, in Great Bend, Kansas, Donald was the eldest son of Joseph W. and Eleanor Z. (Boor) Klug. Raised in the heartland of the United States, his Midwestern upbringing instilled in him a foundational work ethic and a deep sense of familial responsibility.
Coming of age during a pivotal era in American history, Donald answered the call to serve his country by joining the United States Navy during the Vietnam War. His military service was a defining chapter of his life, shaping the disciplined approach, strategic mindset, and resilience that would later become the hallmarks of his professional career.
Upon completing his honorable military service, Donald pursued higher education with rigorous focus. He attended Kansas State University, where he earned a Master’s degree in Accounting. This advanced academic credential provided him with a comprehensive understanding of economic principles and institutional finance, laying the groundwork for a distinguished career in public accounting.

Armed with his master’s degree and the prestigious Certified Public Accountant (CPA) designation, Donald embarked on a career characterized by analytical precision, ethical rigor, and trusted advisory. He reached the zenith of his professional journey during his extensive tenure at BKD, LLP, in Springfield, Missouri.
