Making its debut on the PPAI Top 100, Grossman Marketing Group (PPAI 281988, Gold) acquired Cooley Group — the largest in its 115-year history — and strengthened its capabilities in healthcare and higher education while adding experienced team members aligned with its service-driven culture. Grossman is also on PPAI’s Greatest Companies to Work For list.
The Woburn, Massachusetts-based company completed its first major brand refresh in nearly two decades, launching a website positioning it as a brand execution partner. Internally, it invested in technology, systems and training to support client programs, including e-commerce platforms and enterprise-level reporting capabilities.
Grossman earned EcoVadis Gold in 2026 — placing it among the top 5% of companies globally. The company’s SwagCycle program diverted more than 3.3 million items from landfills and facilitated over $12 million in donations.
