Mary Fredericks

Office Administrator

Mary has been a valuable member of the CJBS team since 1998. As the Office Administrator who wears many hats, she manages the firm’s administrative team, Human Resource Department and sits on the Culture Committee. Prior to her tenure at CJBS, Mary accrued 13 years of administrative experience working at General Motors, Michael Silver & Company, and Medline Industries.

A trustworthy and hardworking individual, Mary devotes herself to the support of the CJBS professional staff—always looking out for the best interests of her teammates. With undergraduate and graduate degrees in Communication, her skill set in Organizational Communication is a valuable asset for her role within the firm, while her double major in Secondary Education has been vital to instructing the firm’s administrative team. Mary attributes her long-term career success to hard work, good listening skills, and her ability to multitask.

Raised in the Northwest suburbs of Chicago, Mary currently resides in the same subdivision where she was raised in Arlington Heights with her husband and their Furry baby – a Shetland sheepdog named Violet. She enjoys Arlington Heights for its wonderful downtown area, good schools, great library, and proximity to expressways. As former volleyball player (now golfer), Mary is a huge sports fan and particularly enjoys following college basketball and cheering on her alma mater, Purdue.
