Based in Quincy, Massachusetts, Granite manages 1.75 million voice and data lines across 650,000 locations. The company, which supports over two-thirds of Fortune 100 organizations, earned its place on the list following an evaluation of independent employee surveys and an assessment of its net societal and environmental contributions. For President and CEO Rob Hale, the accolade serves as a validation of the firm's focus on service and corporate responsibility.

This recognition follows a string of professional milestones for the company in 2026. Earlier this year, Forbes designated the organization as one of America's Best Employers, and the firm collected four Stevie Awards, including top honors for its Corporate Social Responsibility program. These achievements reinforce a broader corporate strategy centered on internal workplace culture and external community engagement.
