Gregory J. Kelley

Portrait of Gregory J. Kelley

Gregory concentrates the majority of his practice defending matters regarding architects and engineers, construction defect litigation and construction accidents. As well, he maintains a smaller portion of his practice in the defense of product liability claims. He splits his time between our King of Prussia, Pennsylvania, and Mount Laurel, New Jersey, offices.

Formerly a litigation specialist for a large casualty insurer in Pennsylvania and Delaware, Gregory was responsible for and developed experience in the evaluation, negotiation and defense strategy for catastrophic personal injury and property damage claims. He also served as an instructor for in-house claims professional seminars on topics of Case Evaluation & Negotiation and Insurance Coverage.

Prior to joining Marshall Dennehey in 2004, Gregory was with a defense firm where his practice involved defending personal injury and property damage matters, focusing on architect and engineer professional liability and construction claims, products, general, premises liability claims and insurance coverage matters.

In 1982, Gregory graduated from Villanova University with a Bachelor of Science degree. While working as an insurance claims professional, he earned his juris doctor from Widener University School of Law in 1992 and is admitted to practice in Pennsylvania and New Jersey.

    • Mediated a favorable settlement for a large Architectural firm that involved construction of an addition to a county prison. The County claimed $4.6M in damages for delays and cost increases, mostly due to negligent construction administration. The Architectural firm had formed a joint venture. Negotiations resulted in a $2M settlement, to which our client only contributed $300K as we were able to show that the substantial majority of the damages claimed pertained to the scope of activities performed by the joint venture partner.

After two days of mediation, the case settled for an amount well in excess of $2 million, but our client contributed only $170,000.
    • Mediated a favorable settlement for an architect in a design error/construction delay/abandonment claim wherein a $1.3 million claim was resolved for $400,000 without litigation and without discovery expenses being incurred.

Results

Successfully Defended Architect in Construction Defect Matter

We successfully defended an architect against a $7 million claim brought by a general contractor in connection with the renovation of a historic, city-block-sized building in Philadelphia. The contractor alleged design errors and sought additional damages under the Contractor and Subcontractor Payment Act, inflating its claim to $16 million. During contentious discovery, we exposed contradictions and falsehoods in the contractor’s testimony, leading to a partial summary judgment that dismissed the bulk of claims against our client. Facing a looming trial and a remaining $4 million claim, we worked with the building owner’s counsel to convince the settlement judge of the claims’ lack of merit. The plaintiff filed for bankruptcy, and the final settlement had to be approved in the Bankruptcy Court. The case settled for just $362,500, with our client paying only $181,250—an outstanding result in a high-stakes dispute.

Six-Figure Claim Against Lighting Designer Dismissed

We obtained dismissal of a six-figure claim in Philadelphia County via preliminary objections. The plaintiff homeowner sued a lighting designer for breach of contract, negligence for $23k in remediation costs, statutory remedies for treble damages and legal fees. The plaintiff alleged the lighting designer was a home improvement contractor who violated the Home Improvement Consumer Protection Act (HICPA) and Unfair Trade Practices and Consumer Protection Law. The plaintiff omitted pertinent facts from the complaint. Using judicial notice, we presented facts from public records to show that the design services were performed in the construction of a new home. We argued that HICPA does not apply to new construction and that the gist of the action doctrine barred the contract claim. The court agreed, dismissed the statutory and contract claims, and remanded the $23k negligence claim to Common Pleas Court arbitration.

What’s Hot in Workers’ Comp - News and Results*

RESULTS ​Perry Merlo (Harrisburg) obtained a favorable ruling involving a claimant who sustained a recognized lower back injury while employed by the defendant and continued to seek workers’ compensation benefits. Following an independent medical examination, Perry filed a termination petition alleging that the claimant had fully recovered from her work injury as of September 10, 2025. The claimant opposed the petition and presented testimony from her own medical expert. The judge granted the termination petition, finding the testimony of the defense medical expert more credible than the testimony of the claimant and her expert; and finding that the claimant had fully recovered from her work-related injury as of September 10, 2025. Kacey C. Wiedt (Harrisburg) secured a complete victory involving a alleged hand laceration resulting additional shoulder and upper extremity injuries. The defense successfully demonstrated that the claimant did not sustain the additional injuries alleged, had fully recovered from the accepted injury, and was terminated for performance-related reasons unrelated to his work injury. Relying in part on text messages and photographs that contradicted the claimant’s alleged limitations, the defense secured a decision denying the claim petition in its entirety and granting the termination petition effective June 10, 2025. The claimant recovered no additional benefits despite previously making a $230,000 settlement demand. Anthony Natale III (King of Prussia) secured a complete defense victory involving an alleged ongoing disability following a work-related cervical spine injury sustained in a truck accident. The defense successfully demonstrated that the claimant had been released to return to full-duty work, was subsequently discharged for cause after failing a mandatory drug test, and had fully recovered from his work injury. Following litigation of both the suspension and termination Petitions, the court found that the claimant was capable of returning to unrestricted employment and had fully recovered from his cervical spine injury. Anthony Natale III (King of Prussia) secured a complete defense victory involving an allegation of ongoing orthopedic and neurological injuries, including post-concussion syndrome, resulting from a motor vehicle accident while volunteering for the township. The defense successfully demonstrated that the claimant had fully recovered from her work-related injuries and was exaggerating her symptoms. Finding the defense medical expert more credible, the court granted the termination petition and concluded that the claimant had fully recovered. The court also dismissed all four of the claimant’s review petitions challenging prior utilization review determinations that found her medical treatment to be unreasonable and unnecessary. Anthony Natale III (King of Prussia) secured a complete defense victory involving a low back injury. The defense successfully demonstrated through medical evidence that the claimant had fully recovered from her work injury. Following litigation of the termination petition, the court found the defense expert credible and concluded that the claimant was fully recovered. The court granted the termination petition despite the claimant proceeding without counsel and arguing that personal circumstances prevented her from adequately defending the matter. As a result, the claimant’s entitlement to ongoing workers’ compensation benefits was terminated. . *Prior Results Do Not Guarantee a Similar Outcome NEWS Congratulations to Kacey Wiedt on being named Best Lawyers in America® 2027 "Lawyer of the Year" for Workers' Compensation Law - Employers.
