Trotter and Associates Inc. Gifts New Santa Cottage to the City of St. Charles

By Mark Dupree • December 5, 2025
The unveiling of the new Santa Cottage during St. Charles’ Holiday Homecoming was a highlight of the season. Trotter and Associates, Inc. is grateful to support this project and continue a tradition that brings joy to families throughout our community. On December 3rd, TAI staff and their families enjoyed a special evening inside the new cottage with Santa. The space felt especially warm—Santa made sure to point out his fireplace—setting the tone for a night of hot chocolate, photos, and shared moments.  We’re proud to have called St. Charles home since 1999 and to contribute to experiences that strengthen our community.

The TAI Team consisted of Steve Cieslica, Nico Beltran, Jessy Stouffer, Reed Stracener, Grant Hattendorf, Leah Fields, Allison Nguyen, Jillian Kiss, Dave Bronars, Irena Hix, and Mark Dupree. TAI staff members have volunteered for and supported Feed My Starving Children for many years, and our team is excited to participate in next year’s MobilePack Event, scheduled for November 12-15, 2026.
