Petrick played an instrumental role in helping train upcoming Universal Bankers and managing CSB’s IRA accounts, in addition to her Universal Banker duties.

Outside of CSB, Petrick has been a driving force in the community by leading and promoting the Union Grove Rails to Trails project as its Vice President. She also supports the community by volunteering her time at Leadership Union Grove (Co-Chair), the Yorkville PTO, Relay for Life-Union Grove, the Kiwanis Club of Union Grove, Yorkville 4-H and by serving community meals twice a month at St. Robert’s Bellarmine Church.
