Brien Buccilla, 42, of Tucker, was killed in a single car accident near his home in the early hours of Sunday morning.
He was the owner of American Signature Print and had recently formed a weekly networking group called Operation Reciprocity that met on Wednesdays at Matthews Cafeteria.
"Brien was a huge supporter of Business After Hours and a good friend," said Hometown Lenders' owner Art Wood in an email.
Buccilla is survived by his five-year-old daughter Brianna as well as his ex-wife, parents, and brothers and sisters.
Services will be held Thursday, Oct. 11 at 2 p.m. at the Brock Fisher Funeral Home, 3742 Chamblee Dunwoody Road in Atlanta.
"I really just don't know what else to say," Wood said. "My heart hurts for his little girl and the rest of his family."
