Trotter and Associates, Inc. (TAI) is a full-service municipal engineering firm that has proudly served our hometown of St. Charles for 25 years!

This year, TAI was honored to support The Band of Brothers who performed in the STC Holiday Homecoming Parade! The band members are active and retired firefighters who made the evening even brighter, and we thank them all for their service.

From all of us at Trotter and Associates, we wish everyone a Wonderful Holiday Season and a Very Merry Christmas!
