Successfully Defended a Claim for Failure to Diagnose Infectious Endocarditis After a Periodontal Procedure

We successfully defended a claim for failure to diagnose infectious endocarditis after a periodontal procedure. The plaintiff, who was 56 at the time, was diagnosed with streptococcal endocarditis after undergoing periodontal surgery with our client. As a result, he required an aortic valve replacement and claimed he had to sell his business as he could no longer work. It was asserted at trial that our client, the periodontist who performed the surgery, and the co-defendant dentist failed to recognize signs and symptoms of potential infectious endocarditis in post-op interactions with the plaintiff. The claim also alleged that had the plaintiff been diagnosed sooner, he would not have required open heart surgery and could have successfully been treated with antibiotics only. We argued that the appropriate standard of care was followed and that the plaintiff’s damages were unrelated to the care and treatment provided by their client.

On the Pulse... Mount Laurel Office: A Cornerstone of Defense Litigation in South Jersey for Over 40 Years

June 30, 2026

Marshall Dennehey established its first office in southern New Jersey in 1984. Since that time, the “South Jersey” office, now located in Mount Laurel, has grown to be the second largest Marshall Dennehey office outside of Philadelphia. With 56 attorneys and approximately 75 support staff, this office fully services our clients across the spectrum of defense litigation in South Jersey. As one of the largest law offices primarily dedicated to South Jersey, we are able to provide our clients an unparalleled depth of experience and knowledge, reinforced by long-standing relationships with the local bar and bench. The success of this office is based upon many factors, not the least of which is the depth of talent and experience we offer our clients. Our office is composed of many long-time residents of New Jersey, and we have the benefit of being staffed by individuals who have dedicated their careers to Marshall Dennehey, having worked for the firm for over 20, and in some cases, over 30 years. Our office administrator, Sheila Stanley, has been with the firm for 40 years and is an invaluable leader. Coupled with the broad-based resources and experience of the firm, we are able to provide our clients with the highest level of defense litigation support in areas including professional liability, health care liability, casualty, and workers’ compensation.The Mount Laurel Casualty Group makes up the largest group of attorneys in our office. Supervised by Barbara Davis, this group includes accomplished, long-time shareholders and trial attorneys who handle cases across the casualty spectrum. They are supported by a skilled group of associates who routinely sit second chair and otherwise support trial counsel at every level. Jeffrey Rapattoni, Assistant Director of the firm’s Casualty Department, serves as Chair of both the SIU/Fraud Litigation Group and the PIP Litigation Group. Our attorneys offer our clients aggressive and specialized knowledge evidenced by their record of success.Our professional liability group, the second largest in the firm behind Philadelphia, handles a broad range of matters, from architectural, engineering, and construction defect litigation, to real estate liability, public entity and civil rights litigation, and employment law. Our PL group is supervised by Matthew Behr, and is anchored by seasoned litigators and talented associates.The Mount Laurel Worker’s Compensation Group is led by Bob Fitzgerald, who has been with the firm for 25 years. He leads a successful team of attorneys who are well known within the worker’s compensation bench and bar in South Jersey, and their longevity and high regard within the community affords our clients the highest level of service. Our Health Care Group is led by Lynne Nahmani, who has been with the firm since law school -- over 35 years. The Health Care Group defends and routinely tries cases including medical malpractice, hospital/acute care malpractice, long term care litigation, nursing malpractice, dental malpractice, allied health professionals' malpractice, and professional board matters, among others. Collaboration has always been a cornerstone of the culture of Marshall Dennehey, and this is nowhere more evident than in the Mount Laurel office. While our attorneys generally practice within their groups, the benefit of having a broad base of litigators allows us to work as a cross-functional team when needed. This provides our clients with the benefits of diverse expertise and collaboration and provides our attorneys with mutual resources at their fingertips. In addition, it allows for our attorneys to continue to learn from each other and work together to continue to lead the market in South Jersey.
