Mary is a valuable member of the CJBS team and has been with the firm since 1998. She serves as the office administrator, managing the firm’s administrative team. She also sits on the firm’s 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, keeping confidential information confidential and always looking out for the best interests of her teammates. Though she didn’t intend to pursue a career in this field, she was hired to an administrative position in 1988 and simply continued on from there. Mary attributes her career success to hard work, good listening skills, and her ability to multitask.


Raised in the Northwest suburbs of Chicago, Mary currently resides in Arlington Heights with her spouse and her new Shetland Sheepdog puppy, Violet, who definitely keeps her on her toes. She enjoys Arlington Heights for its good schools, great library, and proximity to expressways. A former volleyball player, golf is more Mary’s speed, these days. She is a huge sports fan and particularly enjoys following college basketball and cheering on her alma mater, Purdue.


Favorite book: To Kill a Mockingbird by Harper Lee
