Timothy Tomasik has handled some of the most complex and high-profile cases at Clifford Law Offices, including the scaffolding collapse at the John Hancock Center where several people were injured or killed that settled for $75.2 million. He worked round-the-clock on the World Trade Center property damage litigation surrounding the tragic 9/11 air crashes that settled in 2011 for $1.2 billion. He handled the case involving the crash of the private jet that killed the younger son of NBC Sports Chairman, Dick Ebersol, where a chartered Challenger jet crashed moments after take-off in November, 2004. His elder son dragged his dad out of the fiery plane. National Transportation Safety Board reports indicated the plane's wings were not de-iced in the freezing weather.  He was part of the legal team that worked on the high profile trial of internationally acclaimed violinist Rachel Barton which resulted in a $29.6 million verdict.

Tim is not afraid to take on corporate giants in order to see that justice is done.  Another high-profile case which Tim handled involved the toxic alcohol poisoning death of a Northwestern University freshman.   His parents have started the Red Watch Band program which makes students more aware of alcohol poisoning at universities across the country, including now Northwestern. Tim also brought an action against the Chicago Cubs on behalf of the mother of a 21-year-old man who was killed when a car wash/storage unit owned and operated by the Chicago Cubs collapsed on him during a storm. He suffered severe head, neck and spine injuries and died eight days later. The dilapidated structure had been earmarked for demolition.  That case settled for $2.5 million.   He was counsel with Robert Clifford representing a medical doctor who was paralyzed as a result of negligently administered spinal anesthesia while he was a patient. The two-week trial resulted in a $13 million verdict that was affirmed by the Illinois Supreme Court on several important issues related to trial practice and agency. He worked on dozens of cases involving hemophiliacs who have been infected with the HIV/AIDs virus from tainted blood which resulted in a successful confidential settlement. He tried a case on behalf of a woman severely injured in an auto collision with a Commonwealth Edison truck where he and Bob Clifford obtained a $14 million verdict.
