RETTEW has grown from a local company to a top engineering design firm — a regional and national power with offices throughout the Northeast.
Multiple locations give our clients the ability to work with a local team but with all the benefits and resources of a large firm.
This reach allows us to have boots on the ground for our clients in more places, to meet the people we serve, face-to-face, on the jobsite and in the communities where they live and work.
We choose our office locations based on where we can have the best and most impact for clients and the community. Many of our offices are in thriving downtowns and in up-and-coming neighborhoods, allowing us to become part of the fabric of the people around us.
Here’s where you can find us:
