About

Delivering thoughtful, start-to-finish engineering solutions through lasting partnerships.

Who We Are

Prein&Newhof is built on the belief that long-term thinking matters. We’re committed to looking beyond immediate needs to deliver solutions that stand the test of time. Our core values guide everything we do. We don’t take them for granted. Instead, we work intentionally to live them out, day after day.

  • Doing the job right, even when it’s hard
  • Putting others’ needs ahead of our own
  • Making time to learn and grow
  • Taking thoughtful risks and owning the outcome
  • Always telling the full truth

Our Story

Ed Prein and Tom Newhof founded our firm in 1969 to challenge the conventional way projects were delivered. Their belief—that great infrastructure requires continuity, commitment, and care—set the tone for everything that followed. Today, as a new generation leads Prein&Newhof forward, we remain grounded in that founding vision while charting bold new paths to serve our clients, support our communities, and shape the future of engineering.

What started as a two-person venture has grown into a company of more than 170 people across Michigan. Over the years, we’ve expanded our services to include civil engineering, surveying, airport engineering, geotechnical and environmental consulting, landscape architecture, GIS, CAD, asset management, grant assistance, and more.

Our growth has always been intentional. In 1974, we opened an environmental laboratory to better support our clients. We added offices in Holland (1994), Muskegon and Kalamazoo (1997), and Cadillac (2013) to be more accessible to the communities we serve throughout Michigan. Today, we’re proud to be one of Michigan’s most versatile and collaborative civil engineering firms.
