Joseph is a shareholder in the Health Care Department. He focuses the majority of his practice on the defense of various medical/psychiatric providers and facilities in medical malpractice, dental malpractice, complex health care liability matters and premises liability.

Joseph has a rather unique background, which will undoubtedly serve him well in handling matters in the health care liability field. From 2004 until 2007, he was involved in representing plaintiffs in hundreds of actions brought against pharmaceutical companies covering a wide array of drugs. Mass torts included Vioxx, Bextra, Celebrex, Viagra, Adderall and ReNu with MoistureLoc.

Since 2008, Joseph has been extensively involved in defending various medical providers in medical malpractice cases. He has obtained dismissals for several physicians and hospitals. He has also represented hospitals and physician groups in health care liability matters and through use of surveillance experts, was able to have cases dismissed against hospitals and physicians. He also successfully handled an Immigration Customs Enforcement Audit for a major Philadelphia corporation.

Joseph also has experience in trademark/copyright litigation and licensing. He has represented national corporations in the areas of retail, specialty food products, hair care products and toys in trademark and copyright litigation matters.

In 2001, Joseph graduated from Temple University cum laude, majoring in corporate law. At Temple, he was involved in the marching band, basketball pep band, orchestra, Student Judicial Board, Business Honors Program and the law fraternity Phi Alpha Delta, where he competed in several mock trial competitions.

Joseph graduated from Widener University School of Law, magna cum laude, in 2004. He was involved in Law Review and received the Senior Staff Award. He was also the treasurer of the Trial Advocacy Honor Society and competed in several mock trial competitions. Joseph received the Widener University School of Law Outstanding Service Award upon graduation, as well as the American Bankruptcy Institute Medal of Excellence.
