A half-century of commitment.

RETTEW brings our clients’ goals and dreams to life on time and on budget, with an emphasis on quality and safety.

Our expertise is wide and varied: We offer more than 450 engineering, environmental, surveying, planning, safety, and related consulting services in a range of markets. Spanning so many disciplines allows us to connect all the dots, to see how every piece of a project affects the other.

We strive to completely understand your vision for your project—and for your business as a whole — and then we get to work. This big-picture understanding allows us to anticipate your needs and stay ahead of emerging trends. Our innovative approach means discovering solutions that may not have been thought of before — and finding more effective, efficient ways to put them into action.

RETTEW’s corporate culture provides a warm and welcoming work environment where employees can thrive, grow, and make a difference in their company and community. This positive atmosphere — and commitment to safety and excellence — contributes to our success in the field.

Our goal is not simply satisfaction; it’s delight.

RETTEW’s staff was very cooperative and extremely professional at all times; all deliverables were on time and any questions were answered quickly. – Greg Zimmerman, Neumeyer Environmental

A history of success.

Founded in 1969, RETTEW began as a small, local firm; today, we have a national presence and employ more than 350 professionals across nine offices. We also offer our team members ownership of our company through an employee stock ownership plan.

Our long list of technical expertise includes civil, transportation, environmental and structural engineering; site planning and design; surveying; safety consulting; subsurface utility engineering; and design-build services. RETTEW has continued to evolve year after year, embracing changing trends and adding new services to meet client needs.

This commitment to growth has landed us on Engineering News-Record’s annual list of Top 500 Design Firms almost every year since 2000. Other accolades, such as the Quality Achievement Award and the Quest for Business Excellence Award, affirmed our quality work and gave us confidence to continually expand our expertise year after year, while keeping our focus on what we do best: supporting our communities.
