Growing With Purpose. Trotter is Now in Oak Brook

October 19, 2026

Trotter and Associates, Inc. is pleased to announce that our fourth office is open in Oak Brook, IL.

 

With our headquarters in St. Charles, IL, and established offices in Fox Lake, IL, and Lake Geneva, WI, Oak Brook expands our regional presence.

This location brings us closer to clients and gives our growing team more space to collaborate, contribute, and engineer projects for the communities we serve.
 
Trotter doesn’t simply add another “pin” to the map. We grow where it makes sense for our clients, our team, and the future of the firm.
 
Oak Brook has taken its place on the map...Stay Tuned.
