It is a truth universally acknowledged that no matter where she shows up, Heidi Dalenberg is fully equipped to do battle. When Heidi takes on a case, her clients reap the benefit of her considerable knowledge, experience and intense personal investment, as well as her ready sense of humor. She is tenacious in investigating her clients’ cases and creative in her development of strategies carefully designed to protect their business interests.

She has defended clients in class actions and other complex civil litigation involving claims ranging from federal and state antitrust and RICO cases to matters of consumer fraud, product liability, and alleged civil rights violations. She has invested more than two decades working with the ACLU of Illinois as part of a team that took on the Illinois Department of Children and Family Services, winning and now enforcing a hard-won consent decree against the State for providing inadequate care to children in Illinois’ foster care system. In short, she’s not afraid of a fight.

And make no mistake, Heidi keeps herding cats – literally - when she gets home. There, the battle of wits continues with Mojo and Tallulah, two fiendish felines who believe that the human race was created for their pleasure and amusement. Anyone who assumes that Heidi is easily intimidated is making a mistake.
