He then transitioned from finance to operations, demonstrating his impact on the company’s growth both nationally and internationally. Under Don’s leadership, CDS secured business with Costco across the United States, Mexico, Korea, Japan, Taiwan, Australia, Spain, France, and Canada.

He created programs that provided consistency in the quality and standards at CDS and across all Daymon Interactions events, lending its efficiencies and impactful results to its retail partners.

Don received two PDS Outstanding Achievement Awards (in honor of the company’s co-founder, Peter D. Schwartz) for his financial contribution as well as his impact on Daymon Interactions’ international expansion.

He believes that the strength of any organisation is its people, and he is proud of the dedication and results his team achieves around the world.
