Marshall Dennehey’s Advanced Trial Advocacy & Mock Trial Program Turns 25

2025 marked the 25th anniversary of Marshall Dennehey’s Advanced Trial Advocacy & Mock Trial Program—an in-house initiative that has helped shape some of our firm’s most confident and capable trial lawyers.

On the Pulse…Our Philadelphia, Pennsylvania, Office

December 1, 2022

As the managing attorney of the Philadelphia office of Marshall Dennehey, I am happy to have this opportunity to tell you about our corporate headquarters office. Housing the largest contingent of lawyers in the firm, the attorneys in our Philadelphia office protect the interests of our clients in all four of the firm’s departments—Casualty, Professional Liability, Health Care Liability and Workers’ Compensation. The three members of our firm’s Executive Committee—G. Mark Thompson (CEO and President), Howard P. Dwoskin (Chairman of the Board of Directors and Treasurer) and Craig S. Hudson (Senior Vice President and Assistant Treasurer)—maintain offices in Philadelphia. In addition to our attorneys, many of the backroom operations of the firm are handled by personnel in the Philadelphia office, and all non-lawyer administrative directors are based here including Colleen Bannon, our Chief Operating Officer. Colleen has a storied history with the firm (more than 40 years!), and before her promotion to COO, she was a practicing shareholder and also held the positions of Director of Human Resources and Director of Litigation Support. With oversight for our 19 offices across seven states, she is in frequent consultation with members of the Executive Committee and all of our office managing attorneys. Frank Stransky, Chief Financial Officer, is housed in Philadelphia, along with Pattie Day, Director of Billing and Accounting. Between the two of them, all issues concerning billing, accounting and finance are managed firmwide. Nané Pr’Out, Director of Information Technology, is also housed in the Philadelphia office. Nané manages a team of over 40 IT professionals who provide support for all operations of the firm. From time to time, some attorneys questioned whether we needed such a large IT department. When COVID–19 hit in March of 2020, thanks to the IT Department, we were able to have over 1,100 employees connected and working from home in less than one week. After that, those same attorneys were saying, “I am so happy that we have such a big IT Department.” Our IT team is first rate and does all that it can do to facilitate the practice of law at Marshall Dennehey. Karen Williams is Marshall Dennehey’s Director of Human Resources. She and her team provide all manner of support in reference to a myriad of human resources issues, in addition to managing the firm’s comprehensive benefit program. They also facilitate our annual United Way giving campaign. Joseph Goldshear and Jennifer Becker currently serve as Co-Directors of Marketing & Business Development at the firm. Joe has been in that role for 14 years and will be stepping down at year-end 2022, when Jennifer will take over the role in full. We are fortunate that Joe will remain with the firm as a Senior Advisor, to provide assistance to Jennifer as she progresses through her first full year as director. Backed by a creative and impressive group of marketing and public relations professionals, the marketing team works hard to promote the good works of our individual attorneys and the firm as a whole. Lisa Ricchezza is our Director of Paralegal Services with oversight for our approximately 130 paralegals spread throughout our 19 offices. Lisa travels to the various offices and provides training, direction, assistance and guidance to our paralegal team. Our paralegals are an integral part of Marshall Dennehey and provide first-rate, cost-effective representation on behalf of our clients. Christopher Hansen is the firm’s Director of E-Discovery and Litigation Support. In the cyber world, the management of documents in a litigation setting can be a massive undertaking. Getting these documents into a format in which they can be reviewed, and also arranging for relevant documents to be presented at trial, is often beyond the technical capabilities of our lawyers. Fortunately, Chris and his team provide ample guidance in that regard. Lawrence Schempp is our Director of Professional Development. Larry arranges a number of associate training events across the firm each year that provide advice and direction on how to succeed in protecting our clients’ interests. Larry also orchestrates an in-house mock trial academy each summer where eight senior associates are selected to try a case in the mock trial courtroom of our Philadelphia office. Our summer law clerks serve as the jury, and seasoned trial lawyers at the firm serve as faculty. Participants are critiqued in the areas of opening statements, direct and cross-examination, and closing arguments. While the participants find the trial to be somewhat nerve-racking, they always express gratitude for the learning process and experience. Lastly, Larry oversees the provision of CLE credits in each of the seven states where the firm maintains offices. The content of the CLEs is wholly relevant to civil defense litigation practitioners. Sandy Caiazzo is Marshall Dennehey’s Director of Administrative Services. Sandy manages all administrative assistants in the firm as well as their supervisors and managers. She also serves as the firm’s Lateral Integration Coordinator. Like COO Colleen Bannon, and many other employees of the firm, Sandy has never worked any place other than Marshall Dennehey. She joined the firm out of high school and has been with us for over 40 years. Jay Rothman is General Counsel to the firm and is assisted in that role by Shane Haselbarth. Both Jay and Shane have only worked at Marshall Dennehey. Prior to being named General Counsel, Jay had a robust practice in the Professional Liability Department. Shane is an accomplished member of our firm’s Appellate Advocacy Practice Group and maintains that work while assisting Jay on the many issues that confront the firm. We are lucky to have two such astute lawyers to protect the firm. Now that I have highlighted several firm leaders housed in the Philadelphia office, I want to highlight a few Philadelphia office attorneys. John Hare is a member of the firm’s Board of Directors and Chair of our Appellate Advocacy and Post-Trial Practice Group. John has litigated more than 500 appeals in the state and federal appellate courts and is a Fellow of the American Academy of Appellate Lawyers. John formerly served as Chair of the Pennsylvania Supreme Court’s Civil Procedural Rules Committee. He has edited and co-authored two books on Pennsylvania appellate courts. The Supreme Court of Pennsylvania, Life and Law in the Commonwealth, 1684-2017 was published by the Pennsylvania State University Press in 2018, and Keystone of Justice: The Pennsylvania Superior Court, 1895-1995 was published by the Commonwealth of Pennsylvania in 2000. Mohamed Bakry is a young shareholder at Marshall Dennehey. An active member of the volunteer community, Mohamed serves as Chair of the Board of Justice for Our Neighbors of the Delaware Valley, an immigration legal service nonprofit organization. He is also the Second Vice President of Board of Directors of The Lawyers’ Club of Philadelphia, a social and educational organization working to promote comradery among members of the bench and the bar in the Philadelphia area. Mohamed is passionate about, and dedicated to, the principles of diversity and inclusion, and he currently serves on Marshall Dennehey’s Diversity, Equity & Inclusion Committee. He is also a member of the Federation of Defense & Corporate Counsel, an association of vetted and premier defense and corporate counsel and industry executives dedicated to leading the profession by advancing the principles of integrity, professionalism and civil justice. Melanie Foreman, associate in the Casualty Department, is heavily involved in the Philadelphia legal community. She is a board member of Community Legal Services of Philadelphia (CLS) and co-chairs its Leadership Council and Board Development Committee. Melanie is the founder and Chair of Justice Rising, a young professionals’ organization associated with CLS that is dedicated to access to justice for all. She is also a member of the Board of Governors of the Philadelphia Bar Association and sits on the association’s Large Firm Associates Committee. Finally, Melanie was recently invited to join the Board of Trustees of the Philadelphia Bar Foundation, which is the charitable arm of the Philadelphia Bar Association. We are proud of John, Mohamed and Melanie, and the many other attorneys in our Philadelphia office and elsewhere who are doing incredible things that are law-related, but also outside of the practice of law at the firm. Lastly, the Philadelphia office, and our neighboring offices throughout the region, reached a significant milestone in 2022. For the 10th consecutive year, Marshall Dennehey was selected one of the Philadelphia region’s “Best Places to Work” by the Philadelphia Business Journal. The award recognizes the firm’s achievements in creating a positive work environment that attracts and retains employees through a combination of benefits, working conditions and company culture. We are proud of this recognition, as expressed by our President & CEO, G. Mark Thompson: “Ten years is a long time to be recognized for anything and the fact that our employees remain engaged and happy makes us think we must be doing something right. A lot has happened in the past decade, but through it all we have emerged stronger together. I could not be prouder of our firm and all of our employees, and we will continue to do whatever we can to continue to improve our working environment so that all of our employees have the opportunity to succeed.” I hope that this overview provides you with some idea of the scope of the operation in the Philadelphia office that I am so privileged to participate in managing. I also hope that each of you reading this has a wonderful and peaceful Holiday Season and I wish you a happy and healthy 2023. *Buck is the managing attorney of our Philadelphia, Pennsylvania, office.

Mitigating Long-Tail Liability: Delaware Court Reaffirms Five-Year Workers’ Compensation Deadline

Williamson v. Donald F. Deaven, Inc., No. N25A-07-004 FWW, 2026 LX 252526 (Del. Super. Ct. June 2, 2026) Claimant was involved in a compensable industrial work accident on May 12, 1995, for a low back injury.  Following this, he received compensation for temporary total disability benefits from July 1996 to September 1996 and for sustaining a permanent impairment in 1997 and 1998. For the next 23 years, the claimant continued treatment and paid his own medical bills without submitting them to the employer’s insurer. In November 2021, the claimant filed a petition seeking payment for medical expenses, including prospective surgery and a resulting period of total disability. The employer moved to dismiss the petition, arguing it was barred by Delaware’s five-year statute of limitations (19 Del. C. § 2361(b)). Pursuant to 18 Del. C. § 3914, insurers must provide prompt written notice of the applicable statute of limitations to invoke the five-year deadline. Due to the age of the case, neither party had a comprehensive file of the claim and the Board had archived its file of the matter. The carrier’s computer system retained only bare information indicating that payments occurred and agreements and receipts were filed with the Board in 1997. While the claimant argued that the employer could not prove it provided the mandatory statutory notice, the Hearing Officer recovered the archived file, which contained two “Receipts for Compensation Paid” signed by the claimant. The receipts explicitly contained the required five-year limitation language, which the claimant testified to signing at the hearing. The claimant also attempted to introduce evidence of payments he claimed the employer made, which would have extended the statute of limitations. As a preliminary matter, the hearing officer excluded the testimony about the payments because the claimant did not produce them to the employer. The Board found in favor of the employer and dismissed the claimant’s petition as time-barred. The claimant appealed the Board’s decision, arguing that he never received adequate notice of the statute of limitations and that the hearing officer’s evidentiary ruling was an abuse of discretion. The Court held that the archived, signed receipts constituted substantial evidence that the insurer fulfilled its statutory notice requirements. Therefore, the claimant’s petition was time-barred under the statute of limitations provisions of 19 Del. C. § 2361(b). Furthermore, the Court reinforced strict procedural compliance: it rejected the claimant’s attempts to introduce evidence of payment on appeal, ruling the argument was waived for failure to preserve it while the matter was still before the Board. This recent ruling by the Court underscores the importance and necessity of robust data preservation and precise compliance with notice requirements. For risk managers, employers, and insurers, the decision highlights how tight administrative execution protects against catastrophic long-tail liability.

Congress Passes Financial Exploitation Prevention Act

On June 25, 2026, the House passed the Financial Exploitation Prevention Act of 2025 (“the Act”) by a vote of 414 to 2. The Act allows financial advisors and firms to delay suspicious transactions regarding the accounts of clients who are 65 or older, if they believe financial exploitation has occurred or is about to take place. With the advancement of technology and AI, the House’s overwhelming bipartisan passage of the Financial Exploitation Prevention Act represents an important step in strengthening the financial industry’s ability to combat the growing threat of elder financial exploitation. The Act recognizes what advisors have long known that financial professionals are often the first to detect suspicious behavior but have historically lacked clear legal authority to intervene before irreversible financial harm occurs. From the industry’s perspective, the bill accomplishes several important objectives, including the following: (1) Provides a practical “pause button” by allowing financial professionals to temporarily delay certain transaction requests when there is a reasonable belief that a senior or vulnerable adult is being financially exploited; (2) Empowers financial professionals to act by providing greater certainty that firms can act in good faith to protect clients without unnecessary legal risk; and (3) Strengthens investor protection without sacrificing client rights by allowing temporary delays based on a reasonable suspicion of exploitation, which is intended only to allow additional review and not to deny clients access to their money indefinitely. In sum, the Financial Exploitation Prevention Act will equip financial professionals with practical, carefully tailored tools to stop suspected financial exploitation before client assets are lost. By allowing firms to temporarily delay suspicious transactions under defined circumstances, Congress is recognizing the critical role advisors play as the first line of defense against increasingly sophisticated fraud schemes. The Act strikes an appropriate balance between protecting vulnerable investors and preserving individual financial autonomy, while reinforcing collaboration among advisors, families, and law enforcement to combat financial exploitation. The bill now awaits Senate action.

No-Cause Jury Verdict Secured in Wrongful Death Trial

We successfully obtained a no-cause jury verdict in a 13-day wrongful death trial. The decedent, a 59-year-old man, was admitted to the emergency room on February 15, 2019, with complaints of abdominal pain, decreased appetite, and constipation, despite the use of laxatives. The patient did not complain of any nausea, vomiting, or diarrhea. He had a significant medical history including diabetes, hypertension, prior coronary artery stenting, morbid obesity (with past gastric bypass surgery), longstanding ventral hernia, and back pain. A CT scan revealed multiple hernias and a potential closed-loop bowel obstruction, leading to a surgery consultation. Our client, an emergency general surgeon, interpreted that the patient did not have a closed loop or any significant obstruction and recommended non-surgical management. The patient was approved to have clear liquids, and had a vomiting incident shortly after, but our client was not notified. The patient was returned to NPO status, and after improving overnight, he was returned to “clears” and additional medical and renal consults were ordered. Our client did not receive any communications from the residents/nurses of any changes in the patient’s condition. On February 18, 2019, two rapid responses were called due to increased heart rate and vomiting. It is believed that the vomiting resulted in aspiration, causing sepsis, ultimately leading to the patient’s death. During the trial, the plaintiff’s sole medical expert highlighted imaging on the wrong hernia, which called into question all of his opinions in the case. We made key objections related to the expert testimony, limiting what the allegations were, and preventing new allegations from being made. After approximately two and a half hours of deliberating, the jury returned a no-cause verdict.

New Jersey Expands Family Leave Protections Effective July 17, 2026

On January 17, 2026, Governor Murphy signed into law legislation expanding the New Jersey Family Leave Act (NJFLA). Beginning July 17, 2026, significant amendments to the NJFLA will expand job-protected family leave to smaller businesses and more employees across the state. The new law broadens coverage by lowering the threshold for private employers from 30 employees to 15 employees, meaning many smaller businesses will now be subject to the NJFLA. Employees of state and local government agencies will continue to be covered regardless of the size of the employer. The amendments also make it easier for employees to qualify for leave. Under the revised law, an employee will be eligible after three months of employment and at least 250 hours worked during the preceding 12 months, replacing the previous requirement of 12 months of employment and 1,000 hours worked. Currently, New Jersey's Temporary Disability Insurance (TDI) and Family Leave Insurance (FLI) programs provide eligible employees with wage replacement while they are on leave but do not independently guarantee job protection. The recent amendments to the New Jersey Family Leave Act (NJFLA) expand these protections by extending job-protected leave to additional employees. Under the amended law, employees receiving TDI or FLI benefits may be entitled to return to the same position they held before taking leave, or to an equivalent position with the same seniority, status, pay, and benefits. Although the legislation also states that it does not expand or modify an employee's reinstatement rights under the NJFLA, the amendments appear to provide job protection to eligible employees receiving TDI or FLI benefits without requiring them to separately satisfy the eligibility requirements of the NJFLA or the federal Family and Medical Leave Act (FMLA). As a result, some employees may be entitled to longer periods of job-protected leave than were previously available under existing law. With these amendments, New Jersey continues to strengthen workplace protections by expanding access to job-protected family leave for eligible employees. These changes significantly expand access to job-protected family leave and may require employers to update their leave policies, employee handbooks, and HR practices. Notably, employers who were previously not required to administer NJFLA may need to amend their policies and/or create new protocols to come into compliance with the NJFLA. Failure to do so would prove costly, as the penalties for non-compliance are significant.
