Bookkeeper. An O'Fallon native, Trissa spent a decade as a military spouse and has travelled extensively with her husband, Josh, our operations manager. The daughter of a retired colonel and mother of two growing boys, Trissa is a manager of chaos who brings order and calm while helping make sure client accounts are managed properly. No firm can operate without a steady hand at the helm. Trissa works out of our headquarters office in St. Clair County and can best be reached on Thursdays and Fridays.
