Electrical and datacomm supplies distributor Wesco International announced Jan. 15 that it has promoted Greg O’Brien to Senior Vice President of the Global Services Organization within the company’s Communications & Security Solutions business unit.

O’Brien has been in the communications and security products market since 2009 when he joined Anixter, and became Wesco’s Vice President of U.S. Sales when it acquired Anixter in 2020. He was promoted to VP of Global Services in late 2024 before his SVP of Global Services promotion this past December.

In early 2025, O’Brien assumed the role of VP of services, where he focused on scaling and strengthening Wesco’s Global Services organization.
