OUR SERVICES
Trotter and Associates, Inc. is a full-service engineering firm structured to meet the growing needs of our municipal clients. TAI’s staff has the experience required to resolve the complex issues brought on by increased development, a changing regulatory environment and aging infrastructure. Our professionals work closely with the municipal officials to fully understand the community’s priorities and develop solutions that uniquely address the issues.

Over the last decade, municipalities throughout northern Illinois and Southern Wisconsin have been under financial pressure to do more with less. The lack of resources require our clients to make sound financial decisions. TAI is able to assist our clients in evaluation of existing infrastructure, planning for the future needs, and developing capital improvement programs which maximize the value of the community’s resources.
