About

Building Brands. Growing Usage. Earning Community Trust.

For over 50 years, Ilium Associates has been North America’s premier marketing firm for transportation and public infrastructure, transforming how communities understand, embrace, and support essential services. From our headquarters in Bellevue, Washington, with offices in Los Angeles and Newport, Rhode Island, we’ve helped build some of the continent’s most successful transportation systems: transit agencies, airports, ferry operations, toll roads, and parking programs. We achieve this not through advertising alone, but through comprehensive marketing that touches every aspect of the user experience.

We Focus on What Works

We know what moves the needle. Quality service is the foundation, whether it’s on-time transit performance, intuitive airport wayfinding, seamless ferry terminal experiences, or efficient toll road operations. Our marketing amplifies and supports that quality, turning satisfied users into vocal advocates who recommend your services to friends, family, and coworkers.

We’re Different. We Use All the Disciplines of Marketing

While others focus solely on advertising, we deploy the complete marketing toolkit: branding, research, customer service, community relations, public relations, pricing policy, user information, employee engagement, and yes, strategic advertising. We believe a clever ad might sell a soft drink, but convincing someone to change how they travel, where they park, or how they navigate a complex airport requires something far more substantial.

We Understand Your Challenges

Whether you’re facing ridership recovery, passenger volume fluctuations, workforce shortages, safety concerns, service changes, infrastructure improvements, or the need to win public funding, we’ve been there. We’ve guided our clients through a global pandemic, strikes, natural disasters, financial crises, and dramatic shifts in travel patterns. We don’t just market services. We help solve the real operational and political challenges agencies face across every transportation sector.
