Giving Back

John Griffin, Jr.,  grew up in the Englewood neighborhood on Chicago’s South Side & has spent his life giving back to his community. Over the past 35 years, he has created thousands of professional opportunities in the security industry for adults, particularly for minorities in underserved areas of Chicago.

Investing in education is part of Griffin’s greater mission to rebuild the fabric of society in inner-city neighborhoods, where industry, innovation,&  opportunity have become scarce. He founded the AGB Institute, a nonprofit 501(c)3 private school that offers training in a wide range of work-related areas, including security training, workplace safety, business skills & personal development in Chicago.

He also created the Always Giving Back Foundation with his wife, Dr. Denitra Griffin, which focuses on mentoring & life skills for high school students & young adults. To date, the Foundation has served hundreds of young people, providing more than 12,500 hours of mentoring & awarding $73,000 in scholarships.
