Born in Abington, Pennsylvania, to John Joseph “Jack” Bradley and Joan Bradley-Kemp, John grew up working in his grandfather’s corrugated box manufacturing plant, Accardi Box. It was there he discovered a lifelong passion for the packaging industry and dreamed of one day opening his own plant to follow in his Pop-Pop Accardi’s footsteps.
Over the course of his career, John dedicated himself to mastering every aspect of the business, working for many of the industry's leading manufacturers and continually expanding his knowledge and expertise. In 2016, he fulfilled his lifelong dream by founding Diamondback Corrugated Containers. Alongside his children, Madison and John III, he built the company into the largest independent corrugated box manufacturer in San Antonio—a testament to his vision, determination, and unwavering commitment.
John was a devoted husband to his beloved wife, Sarah, and a proud and loving father to Madison, John III, Audrey, Ben, and his two stepchildren, James and Clayton. He cherished his family above all else and found his greatest joy in the time they shared together.
John will be remembered for his generous heart, tireless work ethic, and the lifelong friendships that he cherished. His legacy lives on not only through the family he loved so deeply and the company he built, but also through the countless lives he touched. He will be deeply missed and forever remembered.
“For what is a man, what has he got? If not himself, then he has naught. To say the things, he truly feels and not the words of one who kneels. The record shows I took the blows. And did it my way.”- Frank Sinatra
