WASHINGTON, D.C. — November 26, 2025 –Greystones Group, a woman-owned small business delivering innovative digital solutions to the United States Military and federal government, announced Don Raines joined the company as Chief Growth Officer (CGO).

Don brings more than 40 years of business development experience across the defense and intelligence sectors, including a distinguished 24-year career in the United States Air Force. His military service included extensive work in security and weapons systems acquisition, with over a decade at the National Reconnaissance Office, where he led the procurement of several multibillion-dollar national satellite systems.
“We carefully selected Don based on his previous CGO success growing MacAulay-Brown, Alion Science, and Belcan Government Solutions,” said Sheila Duffy, CEO of Greystones Group. “During his tenure at those organizations, Don helped secure more than $5 billion in awarded contracts, driving year-over-year corporate growth. We anticipate the same level of accelerated growth at Greystones Group with his leadership.”

Don remains active in supporting USAF Academy initiatives, including fundraising for the new Tuskegee Airman Memorial.
