About Us100% Hispanic Minority-Owned Business Enterprise.

NMSDC video


In 1974, Bob Ontiveros saw an opportunity to live the American dream and build a company for himself and his family.  More than 40 years later, the packaging company he originally founded out of the back of his station wagon - Group O, is ranked by the United States Hispanic Chamber of Commerce as one of the top five Latino-owned businesses in the country. 

Group O experienced great growth in the 1980s after being awarded an outsourcing contract for supply chain functions for locally headquartered John Deere, Case, International Harvester, and Caterpillar plants. As business continued to expand, Bob enlisted his son Gregg to manage the supply chain business in 1991, and ultimately appointed him as president of the company in 1999. 

Gregg Ontiveros’ entrepreneurial spirit and continuous interest in emerging technologies have taken Group O from a $49M company in 1999 to the thriving $700M multi-faceted enterprise it is today. Group O has gained prestige for helping Fortune 500 companies like AT&T, Samsung, Michelin, Caterpillar, PepsiCo, and Best Buy turn their most complex business challenges into centers of profitability and efficiency.

Headquartered in Milan, IL, Group O employs over 1,200 people and continues to grow under the leadership of Gregg Ontiveros as President and CEO.
