The Story Behind our Name

AGB means “Always Giving Back.” Our president John Griffin, Jr., grew up in the Englewood neighborhood on Chicago’s South side. His intention was always for our company to be a ministry that assists people in need. Since 2001, AGB has created hundreds of professional opportunities for adults, particularly minorities in underserved areas of Chicago. We also have a foundation that offers business internships and college scholarships to young people.
