ARRO Celebrates 80 Years
ARRO Celebrates 80 Years of Service & Looks Ahead to What’s Next
Eight decades of partnership, progress, and purpose — with our eyes firmly on the future.
As we enter 2026, ARRO Consulting proudly celebrates 80 years of serving communities and partners, guided by a long-standing dedication to trust, collaboration, and excellence.
Legacy That Continues to Evolve
Our firm traces its roots back to 1946, with two organizations — Henry F. Huth and the Environmental Division of Gilbert Associates, Inc. — both known for their responsiveness to client needs. Through decades of growth, change, and strategic partnerships, those foundations ultimately formed what is now ARRO Consulting. While the firm’s name and structure have evolved over time, its dedication to client service has remained constant.
Today, the majority of ARRO’s work comes from repeat clients, reflecting long-standing relationships built on trust and collaboration. In recent years, ARRO has continued to grow through strategic acquisitions that expand the firm’s expertise and geographic reach, including CKS Engineers and Castle Valley Consultants in 2022, Private Utility Enterprises in 2025, and Ott Consulting in 2026.
Built on Partnership and Practical Solutions
ARRO is, at its core, a team of engineers and consultants. But our story goes far deeper than that. For nearly eight decades, we have taken pride in delivering smart, practical solutions rooted in civil and municipal engineering, spanning water, wastewater, planning, environmental services, technology, and more.
Our clients rely on us not only for technical expertise, but for clarity, consistency, and long-term partnership. We understand that today’s leaders are balancing limited resources, evolving needs, and rising expectations. Our goal is to make that responsibility lighter by being a trusted partner — one who sees the big picture, understands the details, and remains engaged through every phase of a project and beyond.
Because good engineering is about more than design. It’s about collaboration, trust, foresight, and making our clients’ jobs easier.
Eighty Years Is More Than a Milestone
Eighty years is more than a milestone. It’s a mark of resilience and perspective, and a reminder that longevity is never accidental. Organizations that endure are the ones willing to evolve, to listen, and to adapt as the world changes around them.
ARRO chooses growth. We embrace fresh ideas, smarter tools, modern technology, and new energy — grounded in everything we’ve learned along the way and committed to doing work that matters for generations to come.
One Team. One Goal. One ARRO.
With eight decades of experience behind us and a new chapter taking shape, we’re energized by what lies ahead — strengthened partnerships, continued excellence, and a united team moving forward together as One ARRO.
We honor everything that brought us here, while embracing what’s next with optimism and purpose.
Here’s to 80 years — and to what comes next.
