John "Jack" Losinger advocates on behalf of businesses and individuals in connection with commercial disputes, with a specific focus on violations of restrictive covenants and the misappropriation of trade secrets and confidential information.
Jack’s wide range of litigation experience - which includes employment lawsuits arising from claims of discrimination and harassment, contractual and estate disputes, environmental cost recovery actions, tax appeals, and municipal court matters - gives him the ability to quickly adapt and pursue a strategy that is in the best interest of his client. By making a concerted effort to understand the strengths and weaknesses of his client’s position, he has had success negotiating favorable pre-suit resolutions and, when necessary, litigating in state and federal court and in arbitration. Jack’s clients have included individuals, small companies and publicly traded corporations.
Jack also has extensive experience conducting comprehensive investigations of a variety of sensitive matters for institutions of higher education and private sector employers, including allegations of inappropriate conduct in the workplace, ethical violations, conflicts of interest, policy violations, and bullying.
Jack is regularly appointed by Chancery Division judges in Essex County and Morris County to serve as the court-appointed attorney for alleged incapacitated persons in guardianship matters.
