There’s more RETTEW in the Central PA area than ever before. 

RETTEW’s boots-on-the-ground are continuing to serve where our clients need us most.

In late November, we opened a new office in State College, PA.

Up to eight existing employees will work from the office, focusing on the firm’s Energy and Environmental Engineering services.

We’ll now have the equipment, connections, and people even closer to our many job sites in the Northeast.

Our new office address is:


Penn State Innovation Park

330 Innovation Boulevard, Suite 104

State College, PA 16803


This is the second office RETTEW has opened in 2017, bringing our firm’s total to 10 offices.
