Throughout his career, Jason has defended hundreds of premises liability, sports and entertainment, retail, dram shop, motor vehicle and product liability matters, trying several cases to verdict.

He has also represented Fortune 500 companies and a considerable number of service providers in sports and entertainment, retail, corrections, healthcare, facilities, restaurant and bar industries.

In addition to his seasoned trial advocacy skills, he regularly uses focused discovery and technology to effectively and creatively represent his clients in a cost-efficient manner. He was also involved in the MDL litigation for a distributor of latex products. Jason regularly serves as a court-appointed arbitrator in the Court of Common Pleas of Lehigh County, Court of Common Pleas of Northampton County and United States District Court for the Eastern District of Pennsylvania.

Results

Unanimous Defense Verdict in Premises Liability Civil Jury Trial Under COVID Restrictions

We obtained a unanimous defense verdict in a civil jury trial in Northampton County, Pa. under COVID restrictions. In this premises liability case, the plaintiff claimed he had slipped on snow and ice on a sidewalk and suffered a comminuted tri-malleolar fracture, requiring two surgeries. At trial, Jason demonstrated that the plaintiff failed to establish that the accident occurred on the property his client maintained as power-of-attorney, or that his client breached any limited duty owed to a licensee. The socially-distanced jury returned its verdict in favor of the defense in one hour.

Reported Cases:
Representative Cases & Matters: Obtained a unanimous defense verdict in a civil jury trial in Northampton County, Pa. under COVID restrictions. In this premises liability case, the plaintiff claimed he had slipped on snow and ice on a sidewalk and suffered a comminuted tri-malleolar fracture, requiring two surgeries. The demand was $130K and Jason's best offer was $75K. At trial, Jason demonstrated that the plaintiff failed to establish that the accident occurred on the property his client maintained as power-of-attorney and that his client breached any limited duty owed to a licensee. The socially-distanced jury returned its verdict in an hour.; Obtained summary judgment for a hospital operating room management consulting company for premises liability claims resulting in alleged traumatic brain injury where demand was $1.9 million.; Obtained defense verdict for a bowling alley for premises liability claims resulting in alleged brachial plexus injury where demand was $250,000.; Obtained a summary judgment in a Monroe County apartment complex slip and fall on snow and ice case. The Court determined that the evidence adduced by plaintiff did not meet the requirements for the Hills and Ridges Doctrine (i.e. that snow and ice had accumulated on the ground in ridges or elevations of such size and character as to unreasonably obstruct travel and constitute a danger to pedestrians). The Court also found that there was no proof of a dangerous condition or notice of the condition to establish a breach of duty. The Court did not reach the merits of our assumption of risk arguments.; Obtained summary judgment for a correctional services food services provider for toxic tort claims of correctional officers alleging exposure to mold in the prison where demand was in excess of $1 million.; Successfully and economically resolved a complex premises liability case at an air cargo distribution hub through creative use of meteorology experts and discovery.; Successfully and economically resolved a complex industrial shelving unit collapse case resulting in catastrophic head injury through creative use of biomechanical and engineering experts.; Successfully and economically resolved a medical product liability case involving a catheter sheath through effective use of engineering and design experts.; Successfully and economically resolved a products liability case involving a motorized yard truck through effective use of engineering and human factors experts.; Obtained summary judgment for a tree removal service based on plaintiff's failure to file action within statute of limitations.; Obtained defense verdict at trial in a low speed motor vehicle accident through effective use of photographs, damages estimates and medical experts.; Successfully obtained dismissal of the distributor of an allegedly defective log splitter.; Successfully defended construction liability case where the demand was $10 million by showing that the action of my client was not the proximate cause of plaintiff's injuries.
