John Freedenberg, a founding partner of the firm, concentrates his practice in the areas of products liability, catastrophic personal injury, and intellectual property litigation. He has handled over 150 trials, 100 of them to verdict, and has had many summary judgments granted making trial unnecessary.

Jack serves as national coordinating counsel for two major manufacturers, and he has handled the defense of numerous products liability actions around the United States. These have included catastrophic personal injury cases and major fire damage cases, and they have involved appliances, household products, controls, power generating and other heavy equipment, high-end products, lift trucks, electrical systems, and aircraft engines.

As a Certified Fire and Explosion Investigator (CFEI), Jack provides Goldberg Segalla clients with a strong competitive advantage in litigation involving damage and injury from fires. He is actively and deeply involved in the investigation phase of each fire case, and in the courtroom, he brings the weight of fire investigation credentials that often match or exceed those of opposing expert witnesses. He has participated in dozens of fire scene inspections and more than 100 laboratory inspections of fire scene artifacts, and he has conducted hundreds of depositions and dozens of trials in fire-related cases. Administered by the National Association of Fire Investigators through its National Certification Board, CFEI is the largest fire investigator certification program in the world. 

Jack has also had the unique opportunity to depose plaintiffs' experts in a wide range of specialties, and he has developed proven techniques for disqualifying "junk science" purveyors under applicable rules of evidence. He utilizes cutting-edge technology and unique strategies in order to, for example, enter into high/low agreements, and achieve the best possible outcome for clients.
