Results

Successful Trial Result Achieved in a Philadelphia Premises Liability Matter

We received a successful trial result in a premises liability matter in Philadelphia Court of Common Pleas. The plaintiff’s expert projected future surgeries and extensive life-long medical care costs of $1.25 million. Much of our defense centered on damages and demonstrating that the projected future medical care was not supported by the actual medical treatment provided. Additionally, video of the incident was used to demonstrate that the plaintiff had actual/constructive knowledge of spilled water in the premises but proceeded to walk in that area anyway. Forty percent comparative negligence was assigned to the plaintiff, and despite the plaintiff’s introduction of the medical cost projection described above, only $50,000 in future medical care was awarded by the jury. The total award, after a molded verdict, was $118,800, which our client viewed as a victory in this venue. 

Real estate agency dismissed from litigation.

The defense prevailed on a motion to dismiss our real estate agency client. The plaintiff filed counts of fraud, deceit, misrepresentation, conspiracy, conversion, invasion of privacy-false light, breach of contract, and promissory estoppel against the agency regarding an allegedly fraudulent transfer of a private residence by the co-defendant seller of the property. We filed preliminary objections, arguing that the plaintiff's claims lacked sufficient specificity and that the plaintiff failed to state a claim upon which relief may be granted. The court dismissed all claims against our client.

On the Pulse…King of Prussia Office: A Historic Legacy and a Dynamic Future of Legal Excellence

December 1, 2025

Situated in the shadow of Valley Forge and the rich history of the Revolutionary War, the King of Prussia, Pennsylvania, office is steeped in history. The office itself has a long history of servicing the counties adjacent to Philadelphia, in addition to Philadelphia. Though once located in the Montgomery County seat of Norristown, this office now sits not far from the King of Prussia Mall and an always active Top Golf facility. The office is also steeped in firm history as it has been affiliated with many of the firm’s founders and leaders through the years, including Jack Warner, Tom Brophy, Christopher Dougherty, Joe Santarone, and Wendy Bracaglia, to name a few. Today, with approximately 40 attorneys and 60 staff employees, the King of Prussia office is one of the firm’s largest branch offices and one of the largest law offices in Montgomery County. The office has long serviced Chester, Delaware, Montgomery, and Philadelphia Counties. We consolidated with our Doylestown and Allentown offices several years ago, and we now also service Berks, Bucks, Carbon, Lehigh, Monroe, Northampton, and Schuylkill Counties. The addition of attorneys from other offices and the acquisition of key talent from other firms through the years has created a dynamic team comprised of attorneys with numerous backgrounds, skill sets, and perspectives. The health care team has been a powerful engine for the office for years and continues to flourish. The group has long-standing client relationships with health care systems and providers throughout eastern Pennsylvania and continues to develop new relationships. Led by attorneys Robin Snyder and Donna Modestine, the group continues to grow, even with the recent retirements of several key health care attorneys in the past several years. In 2024, Gary Samms, one of the most sought-after trial attorneys in Pennsylvania, joined an already stalwart group of attorneys: Joan Ford, Joe Hoynoski, and Gabor Ovari. Recent special counsel and associate additions in the past several years include Kevin Majernik, Jonathan Landua, Evan Pentz, David McColloch, and Julianna Malloy, all of whom have joined us from other firms and have added to an already strong and highly-regarded unit.  Despite retirements of several experienced and senior attorneys in the past several years (we will sorely miss Mark Riley and Ed McGinn when they retire at year’s end) from the Casualty Department, we have pivoted and recently welcomed several talented and energetic associates—Khaliyah Pugh, Richard Lechette, and Ashley Stasak—to our core casualty group, consisting of Michele Frisbie, Michele Krengel, Tim Hartigan, Ed Tuite, and Rob Morton, in addition to those attorneys who strengthened our group after joining us from the Allentown office: Jason Banonis, Steve Keim, and Wendy O’Connor. The casualty attorneys handle a wide array of high-exposure casualty matters, ranging from construction personal injury to serious auto and premises liability matters and everything in between.  Frank Wickersham, Judd Woytek, Tony Natale, Michael Duffy, and Anna Jaoudi comprise the office’s workers’ compensation unit, which routinely achieves favorable results on behalf of their clients and is very well-regarded by the workers’ compensation bar. Tony and Anna also work in our Medicare Compliance Practice Group, providing the entire firm with an invaluable resource in reaching solutions for often complicated questions created by settlements and Medicare issues. Finally, the firm is fortunate to have a group of attorneys who handle a wide array of professional liability matters. They include Audrey Copeland, who handles appeals; Gregory Kelley, who focuses on professional liability and construction defects; Maureen Fitzgerald and Christin Kochel, who handle a wide variety of professional liability cases; and Paul Laughlin, who handles professional liability and health care cases. These added practice areas, and the skill with which these attorneys practice, ensure that the office, the firm, and our clients have access to invaluable resources and representation in numerous practice areas.  The office is defined, in large part, by the skill and talent of its attorneys, but it has had its share of characters and levity through the years, too. There has never been a shortage of social events (Top Golf, happy hours, associate dinners), games (trivia night), music (a staple on the “Class Action” tour circuit) and the occasional awkward photo of an office attorney from yesteryear. The office has always embodied one of the defining features that makes Marshall Dennehey special and unique: “A culture where humor is the great equalizer, and no one is above the friendly jest.” The office is also blessed with hard-working and talented paralegals and support staff, who are an integral part of our success and are led by our dedicated and tireless office manager, Suzie Spitko. One of the office’s primary strengths remains its versatility, both in the various practice groups that provide skilled lawyering and in its capacity to provide representation in numerous venues in eastern Pennsylvania. We have always thrived, in great part, due to our flexibility and adaptability and in bringing on new talent to continue our tradition of excellence. In many ways, the King of Prussia office serves as a microcosm of the firm at large: rich in history but poised for great things moving forward.  Mike is the managing attorney of our King of Prussia, PA office.

Result

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.

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

RESULTS* Ben Durstein (Wilmington) obtained a favorable decision involving a claimant who fractured his patella in a work accident requiring two surgeries. The IAB rejected the claimant’s medical expert’s opinion that he sustained a 25% permanent impairment to the right lower extremity. Instead, the board accepted the opinion of the employer’s medical expert that the appropriate permanency was 13% utilizing the 6th Edition of the AMA Guides to the Evaluation of Permanent Impairment. Tony Natale III (King of Prussia) successfully had a claim petition alleging new injuries and periods of disability dismissed based on full recovery. The claimant was injured when his skid loader was struck by another loader in the process of baling hay. Original injuries were accepted and the claimant returned to work. Thereafter, the claimant abandoned work and filed a claim petition to assert new injuries and extended disability. Cross examination of the claimant’s medical expert stunningly revealed his failure to review claimant testimony, his lack of awareness of a social security disability decision detailing the existence of claimant’s alleged work-related conditions prior to the date of work injury, and his failure to understand that the claimant admitted to full recovery of injuries for which he was continuing to treat. Tony Natale III (King of Prussia) successfully obtained a defense verdict in a Medicare conditional payment lien third level appeal. The United States government alleged a Medicare conditional lien payment was due and owing in the upper six-figure range based on an auto accident and PIP policy for which the government conditionally became the primary carrier. The government argued that our client, the PIP carrier, was the primary payer and, under federal law, must reimburse the government for its conditional lien payment. At the third-level appeal hearing, the government’s position was refuted by the revelation that the date of injury tied to the medical bills associated with the lien was glaringly and chronologically prior to the insurer’s PIP policy date. The court held that based on this evidence and argument, the government could not meet its requirements to assert a lien against our client. A. Judd Woytek (King of Prussia) and John Abda (Scranton) successfully had a workers’ compensation claim petition granted for medical benefits only for a closed period with no wage loss awarded. The claimant alleged multiple injuries as the result of a very minor motor vehicle incident where a co-worker’s delivery van rolled down an incline of approximately six feet, and bumped into the rear of the claimant’s delivery van. He claimed he was thrown forward and suffered head and neck injuries, along with aggravating a pre-existing ankle injury. The claimant was also terminated following the accident for having a large hunting knife in his van, which was against the employer’s workplace violence policy. The judge granted the claim for a mild concussion and an ankle contusion, but terminated medical benefits as of the date of our IME’s. The judge found that no wage loss benefits were payable as the claimant was terminated for cause and work remained available to him. The judge found our medical experts to be more credible than the claimant’s, along with finding our four employer witnesses to all be credible. The trial team was assisted by paralegal Bonnie Zemek (King of Prussia). Eric Scott Thompson (Wilmington) was successful in a workers’ compensation matter in Delaware. On October 15, 2024, the claimant was injured while performing fire training in a multistory building when he tripped over a fire line, injuring his right knee. The claimant received regular and consistent treatment for the right knee through August 29, 2025, when he presented with left knee complaints for the first time. His treating orthopedist diagnosed a hamstring strain. The claimant was next seen October 15, 2025, with continued left knee complaints, and was referred to a total knee doctor within the practice. He was then diagnosed with a posterior root tear of the medial meniscus. Our expert testified that it was not plausible for a lateral hamstring strain to progress to a meniscal tear in two months. The claimant required a total knee replacement that was ultimately performed in February 2026. In the six months between the time of initial presentation with left knee complaints and the total knee replacement, conservative care consisted of a single injection. Our expert testified that posterior root media meniscal tears can respond to conservative care, and it was not known if it would with the claimant because it was not adequately explored. The Industrial Accident Board agreed with our expert and determined that the claimant failed to meet the burden of establishing more likely than not that the left knee complaints were caused by overloading/overuse as a result of the compensable injury to the right knee. They also agreed that the claimant was able to return to work in a sedentary capacity as opined by his physicians and our expert prior to the left total knee replacement and that there were employment opportunities available within his restrictions and capabilities as presented by the vocational expert. As a result, the claimant was no longer entitled to total disability benefits and will receive partial disability benefits for which he is limited to 300 weeks. Michele Punturi (Philadelphia) and Alana Staniszewski (Pittsburgh) had a termination petition granted in a Pennsylvania workers’ compensation case. The petition involved an echocardiography technologist with long-term employment at a local hospital who sustained a right shoulder injury resulting in surgery in January 2024. Following surgery, the claimant was diagnosed with a frozen shoulder and underwent additional surgery in June 2024, with a recommendation for a third surgery. The opinions of the defense medical expert, a Board-certified orthopedic surgeon, were found credible, persuasive, and competent based upon the extensive history he obtained from the claimant, analysis of the mechanism of injury, and review of records, along with comparison of MRIs from October 2023, February 11, 2024, and January 6, 2025, which failed to reveal any causal relationship other than a strain/sprain of the right shoulder. This evidence supported that the claimant had fully recovered, and was not in need of any ongoing medical treatment and/or restrictions. In particular, despite allegations of injuries beyond a sprain/strain, the defense medical expert identified that those allegations were not consistent with what was found at the time of surgery, and elements of the surgery were to treat a chronic and degenerative condition. Additionally there were no ongoing issues or problems with the subscapularis, which was intact, consistent with the follow-up MRI of February 11, 2024, and the claimant did not have evidence of a frozen shoulder. In fact, the MRIs and mechanism of injury, he opined, did not support any injury causing tendonitis or inflammatory conditions within the bicep tendon. Furthermore, multiple days of surveillance footage demonstrated the claimant’s normal use, with the ability to sweep and shovel snow, operate her vehicle, raise her arms above shoulder level, and use a broom – all without any observable difficulty, which challenged the claimant’s credibility of a disability and further established a lack of causation. As a result of this favorable decision, supersedeas fund reimbursement will be obtained for both wage loss and medical benefits through the supersedeas fund recovery process. *Prior Results Do Not Guarantee a Similar Outcome NEWS Heather Carbone (Jacksonville) was a panelist for a webinar hosted by The Workers’ Compensation Claims Professionals (WCCP) Association. As part of the “Meet the Experts” Series, the speakers addressed “Afterthoughts that Undermine a Successful Mediation,” highlighting the pitfalls and challenges of underprepared or unprepared mediation participants. The discussion included appropriate pre-mediation communications, setting of expectations, management of expectations, and working through the unexpected or unprepared. Attendees gained ideas about how and when to prepare, best practices, and the potential for non-parties (spouse, significant other, risk owners-insurers) to have differing perspectives or concerns than the actual employee and employer. On May 21-22, 2026, A. Judd Woytek, (King of Prussia) joined a panel at the CLM Alliance (Claims and Litigation Management Alliance) Work Comp Conference in Nashville to present "We See You: How Employee Engagement Enhances Work Comp Outcomes." Judd and his fellow panelists discussed the positive impact of employee engagement on claim outcomes, return-to-work timelines, and overall claim costs.
