Significant Representative Matters

  • Obtained voluntary dismissal of a dram shop death case where he was able to prove prior to the filing of a complaint that plaintiff's decedent was intoxicated as a result of liquor contained within his home, rather than alcohol allegedly purchased at the client's bar.

  • Prepared successful Motion for Summary Judgment in a conveyor belt death case in which we represented the company who purchased the assets of the bankrupt corporation which manufactured the conveyor belt at issue.

  • Prepared successful Motion for Judgment on the pleadings in a death case on behalf of a methadone clinic. Plaintiff's theory was that plaintiff's decedent was killed by a driver who had been either improperly treated at the methadone clinic or had been improperly permitted to drive following treatment. He successfully argued that no duty exists to a third party motorist under such circumstances under Pennsylvania law.

  • Has handled well over 50 compulsory arbitration cases in counties throughout the Commonwealth of Pennsylvania.

  • Has utilized ADR when appropriate, referring a number of cases to mediation where appropriate.

  • Has assisted in the handling of numerous cases against bars filed by plaintiffs who alleged improper service of alcohol, either to themselves or to other patrons. These cases have involved fatal motor vehicle accidents, assaults, suicide and other significant and serious injuries.
