Alford, 69, provided counsel to the BGA board and its CEO Andy Shaw.
"No one deserves more credit for the recent revitalization of the BGA than Jimmie Alford... We're a stronger organization because of many people, but Jimmie's at the top of the list," said Shaw in a message posted on the BGA website.
In October, the BGA honored Alford for his service and commitment.
The BGA said Alford worked in the nonprofit arena for more than 50 years, starting at the Boys and Girls Club of Chicago before launching his namesake consulting firm, The Alford Group.
He is survived by his wife Maree Alford and three children, according to the BGA.
