Pasadena Deserves More: Tetra Tech Must Invest in the Community That Built Its Success

GUEST OPINION

With a heavy heart and a sense of urgency I address a profound disappointment: the glaring failure of Tetra Tech, a corporate titan headquartered right here in Pasadena for nearly 60 years, to meaningfully invest in and uplift the very community that has nurtured its extraordinary success.

By William Paparian

Since its founding in 1966 at 3475 East Foothill Boulevard, Tetra Tech has flourished into a global powerhouse—a multibillion-dollar defense contractor with massive DOD contracts, boasting ambitious slogans like “Leading with Science” and pledging to positively impact 1 billion people by 2030. Its sustainability reports and web site brim with inspiring stories: employees volunteering hundreds of hours in Fiji for disability support and tree-planting; building playgrounds and supporting food banks in Virginia; delivering toys and care packages in Washington and New York; even sponsoring clean water projects in Honduras and Panama through Engineers Without Borders.

These are noble acts, worthy of praise, but they happen everywhere except here, in Pasadena. A thorough review of Tetra Tech’s public materials reveals no prominent sponsorships of our iconic Rose Parade, no major partnerships with the Pasadena Educational Foundation or local nonprofits tackling homelessness, youth education, or arts programs. No highlighted donations to our food banks, no visible support for Pasadena’s schools, parks, or cultural institutions. No leadership in addressing our own pressing challenges—like affordable housing, environmental resilience, or STEM opportunities for local underserved kids. Yes, Tetra Tech employs people here and pays taxes, that’s the absolute baseline, the bare minimum any corporation owes its host city. But true corporate citizenship demands more: active, visible, headquarters-level commitment. It means prioritizing the community that gave you your start, not treating it as an afterthought while spotlighting efforts thousands of miles away.

Contrast this with another former Pasadena giant, Parsons Corporation. For decades headquartered here, Parsons actively supported local causes—keynote speeches at Pasadena Educational Foundation fund raisers, long-term contributions to STEM programs in our schools, and employee volunteering tied to our community—before relocating its HQ to Virginia in 2019 to be closer to its largest workforce and federal clients. Even after the move, Parsons’ structured “Parsons Gives Back” program continues to channel employee-driven philanthropy into areas where its people live and work today. Tetra Tech has no such excuse: Pasadena remains its global headquarters, yet our city sees none of that structured, celebrated giving.
Pasadena has been good to Tetra Tech—providing talent, infrastructure, and a prestigious home base that enhances its brand. It’s time for Tetra Tech to reciprocate, not with distant gestures, but with real, substantial investment right here. Sponsor our events. Fund scholarships for Pasadena students. Partner with our nonprofits. Lead visible initiatives that showcase your “spirit of giving” in the community that needs it most—ours.

We, the people of Pasadena, deserve better. Let’s hold Tetra Tech accountable. Let’s demand that it step up and truly lead—not just with science, but with heart—at home.
