Wesco International, a provider of business-to-business distribution, logistics services and supply chain solutions, promoted Greg O’Brien to senior vice president of the global services organization within its communications and security solutions (CSS) business.  

O’Brien joined Wesco in 2009 and has held multiple leadership roles within the CSS organization, including leading the U.S. CSS business. Under his leadership, the U.S. CSS business grew into a more than $3 billion operation. 

In early 2025, O’Brien assumed the role of vice president of services, where he focused on scaling and strengthening Wesco’s global services organization. Today, he leads a team of more than 1,000 sales and technical professionals, delivering a comprehensive global services portfolio, including advisory services, data center services, installation enhancement services, project deployment services, managed services and supply chain solutions. These services and solutions fill gaps in staffing and support enhanced productivity, mitigate risk and improve profitability. 

“As services continue to be a core driver of growth and long-term customer relationships for CSS, Greg will focus on expanding our services capabilities, improving execution at scale and ensuring we consistently deliver meaningful, high-value outcomes for our customers,” said Dirk Naylor, executive vice president and general manager, Wesco’s CSS business. “His leadership is critical to how we’re shifting beyond products alone to differentiated solutions that are digitally enabled and built on expertise, execution and trust.”
