Arthur’s love for running began early, but it never faded. From high school tracks in Bethesda to completing 13 full marathons, he ran not for the medals, but for the joy of it — and often to raise money for causes he cared about. He was also the founder of Dubin & Associates, Inc., where he built a career based on fairness, mentorship, and integrity. Beyond business, Arthur found fulfillment in helping others grow — both professionally and personally. In later years, he embraced new roles with the same heart: wedding officiant, nature enthusiast, concert companion, and “Zayde” — a grandfather full of laughter and love.
