When he became IMA President, he said the Institute’s mission “is helping current and future IMA members ready themselves for the challenges facing management accountants.” A strong advocate for the CMA® (Certified Management Accountant) certification, he called it the premier professional program of IMA and vowed to help others see that “its relevance to the business world is unchallenged.”
He also was active in Financial Executives International (FEI) and was named to its Hall of Fame in 2012. A CPA (Certified Public Accountant), he was involved in the American Institute of CPAs (AICPA) and the Texas Society of CPAs.
