Justin is a seasoned litigator whose practice focuses on medical malpractice, nursing home liability, and state board disciplinary actions. In addition to his legal background, Justin also received his pharmacy degree. Licensed as a pharmacist in both Iowa and Illinois, he leverages his deep knowledge in pharmacology, pharmacokinetics, toxicology, physiology, and anatomy to provide strategic, scientifically grounded defense in complex medical malpractice cases.
Justin has handled several hundred medical malpractice matters and has taken nearly 120 cases to trial. Ninety percent of all verdicts were defense verdicts, and roughly 30 of his cases ended in a verdict or mid-trial settlement significantly below the settlement demands. He has represented a considerable number of physicians and pharmacists at state board disciplinary proceedings. He successfully obtained favorable trial verdicts in multiple cases involving potentially high jury awards, including matters involving limb loss, kidney/liver injury, wrongful birth and wrongful death by demonstrating that the physicians were not negligent in the care and treatment that they rendered to their patients. He also handled a case for a physician involved in the Ortho Evra patch mass litigation.
Justin received a Bachelor of Science degree in Pharmacy from Drake University in 1986. While at Drake, he received various honors, including The Norcliff-Thayer Publishing Grant, election into the Order of Omega (honor society), and inclusion on the Dean's List. Justin received his juris doctor from Pace University School of Law in June 1989 where he was involved in the Health Law Program.
After serving a judicial internship with the Honorable John Marbach in the New York Supreme Court, Justin became associated with Jeffrey A. Krompier, Esquire, of Florham Park, New Jersey, from 1989 through 1992. In 1992, Justin became associated with Michael J. Lunga, Esquire of Fairfield, New Jersey, and became a partner at their newly named firm Lunga, Evers & Johnson in 1995. He remained at that firm until he joined Marshall Dennehey in 2007.
Justin is admitted to the bar in New Jersey and the U.S. District Court for the District of New Jersey, and he is a member of the New Jersey State Bar Association, and the American Society for Pharmacy Law. He was appointed to the Medical Malpractice Committee of the New Jersey State Bar Association, as well as the Joint Committee of Essex County Medical and Bar Associations.
Justin is an active member of the community, serving as a member of the Harrington Park Lions Club and, when his daughters were younger, serving as a board member and coach of serveral recreational and travel softball and basketball programs. He is also a consistory member and first vice-president of the Community Church of Harrington Park, New Jersey.

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.

On the Pulse...Our Roseland, New Jersey, Office
September 1, 2023
In February 1993, Roseland became the home of Marshall Dennehey’s North Jersey office. Its lone member, Howard Mankoff, was the original local managing attorney, and he is still with us today. Our initial home was in nearby Livingston, before relocating to our present office for the past 20 years. The Roseland office is located in the heart of North Jersey, in close proximity to two of the state’s largest cities, Newark and Paterson, and is a mere “hop, skip and a jump” to New York City (at least when traffic is light). In 2022, the office underwent a major construction project that included the creation of a beautiful new conference center, installation of state-of-the-art technology and communications systems, as well as new office furniture and decor. Over the past three decades, our office has experienced exponential growth and currently boasts 36 attorneys (24 shareholder/senior counsel, 4 special counsel, and 8 associate attorneys). An additional 3 attorneys joined us after the Labor Day holiday, when they concluded their judicial clerkships. Roseland is one of Marshall Dennehey’s largest offices. Our attorneys specialize in all four of the firm’s essential practice department: Casualty (16 attorneys), Health Care (8 attorneys), Professional Liability (6 attorneys), and Workers’ Compensation (6 attorneys). Many of our attorneys have decades of legal experience and are recognized leaders in their areas of specialization. Our office also benefits from the support of 10 accomplished and dedicated paralegals. Roseland’s Casualty Department is headed by Christopher Block, and includes Matt Schorr (who also serves as Assistant Director of the Casualty Department firmwide), Len Leicht (who received the honor of being named among the 2024 Best Lawyers in America for personal injury litigation), Mike Speer, Tim Jaeger, Alicia Calaf (member of the firm’s Diversity, Equity & Inclusion Committee as well as the Executive Committee Advisory Counsel), Art Bromberg, Julie Dorfman, Josie Scanlan, Sara Mazzolla, Jonathan Williams, Gary Lesser, Paul Lanza (who was recognized as a 2023 New Jersey Super Lawyer Rising Star), Brian Byrne, Hellen Tuckett, and Sean Govlick. Paul and Josie have also been identified as 2024 Best Lawyers: Ones to Watch. The Casualty Department handles a wide variety of cases. Its attorneys aggressively tackle their cases and routinely achieve successful results for their clients, both outside and in the courtroom. The Roseland Health Care Department is supervised by Bob Evers (named as a 2023 New Jersey Super Lawyer, included among the 2024 Best Lawyers in America, named 2024 Lawyer of the Year for medical malpractice law in our region). Other members of the Health Care Department include Justin Johnson and Julia Klubenspies (both of whom also were named as 2024 Best Lawyers in America for medical malpractice law in the Newark, New Jersey, region), Ryan Gannon and Heather LaBombardi (both of whom were named as 2023 New Jersey Super Lawyers Rising Stars), Maura Brady, Dave Tomeo, and Eric Grogan. In the recent past, the Roseland Heath Care Department (in conjunction with our colleagues in the Mount Laurel office) was recognized as runner-up for the Best Litigation Group in New Jersey. The Professional Liability Department in Roseland is led by Will Waldron (who is the supervisor for the Northeast Professional Liability Group) and Sunny Sparano (who serves as Chair of the Architectural, Engineering and Construction Defect Litigation Practice Group for the firm), Howard Mankoff, Wendy Smith, Patricia McDonagh, and Pauline Tutelo. This group has an extremely diverse portfolio of case types and is comprised of some of the most talented and experienced attorneys in their industry. And last, but far from least, Roseland’s powerful and robust Workers’ Compensation Department is headed by Greg Bartley. Other group members include, Rachel Ramsay-Lowe (who currently serves a member of the Executive Committee of the New Jersey State Bar Association’s Workers’ Compensation section), Ida Fuda, William Murphy, Lela Eke, and David Levine. This group has grown in size during Greg’s tenure and successfully litigates a tremendous volume of cases. In Roseland, we draw upon a wealth of experience and a depth to service our clients that goes above and beyond their expectations. Many of our attorneys have successfully litigated cases through trials, arbitrations, mediations, and keen motion practice. In combination with our Marshall Dennehey colleagues in the Mount Laurel office, we have been named a finalist in The American Lawyer Regional Litigation Department of the Year award. Although we are very diverse in our backgrounds, educations, and experiences, we are a tight-knit group (attorneys, para-professionals, and staff) who trust and care for each other, and genuinely enjoy each other’s company. If you are ever in our area, we would love to have you stop by and see for yourselves. *Justin, a shareholder, is the managing attorney of our Roseland, New Jersey, office.
