  • Gerasi v. AT&T et. al.: Obtained summary judgment in a catastrophic construction related electrical injury.  Plaintiff electrician was injured while performing an electrical connection to a circuit breaker and an arc flash occurred. He claimed severe neurological injuries which has permanently prevented him from returning to work.   Plaintiff’s initial demand was $16 million  and he settled with two other defendants for $2.5 million.  Rather than settling with Plaintiff,  Tim, along with David Sethi of Wiedner & McAuliffe , obtained summary judgment on behalf of our client who was the general contractor on the project.

The Sexton Group, Case No. 01 C 6959: A patron of a Chicago restaurant who suffered spinal injuries after falling down a flight of stairs brought suit against the client floor care company.

The jury found in favor of the client after hearing evidence including accident reconstruction analysis.
