Erika Salisbury returns to Trotter and Associates, Inc. as a full-time staff engineer in our St. Charles, IL office.

In September, just before graduation, she passed the Fundamentals of Engineering (FE) exam, earning her Engineer-in-Training (E.I.T.) certification. It is no surprise that Erika has already re-engaged in active projects, bringing both continuity and technical discipline to the team. We are proud to welcome her back to TAI, where she will advance her career while supporting our projects and valued clients.
