A Principal of Bressler since 1990, Mark Tallmadge’s practice is concentrated in trial and appellate litigation involving professional negligence, insurance coverage, insurance insolvency and bad faith issues. In an era where very few lawyers go to court, Mark is a true trial and appellate lawyer, and is valued for his pragmatic approach, negotiating skills and intuitive ability to create synergy where most professionals become mired in strife. When a negotiated solution cannot be achieved, Mark is a litigator whose courtroom experience has proven to be a significant advantage to his clients.

A noted authority in the areas of insurance insolvency and insurance coverage litigation, Mark provides comprehensive litigation representation in the areas of professional liability, environmental claims, and the representation of state insurance guaranty associations. In addition, Mark is the litigator other lawyers turn to when faced with a professional liability lawsuit or ethics grievance. His professional negligence litigation practice is known throughout the state, and he is frequently retained to defend even the most difficult claims.

Mark remains ever mindful of each client’s specific concerns about a given case and is retained again and again for providing a truly objective assessment of the situation at hand. Mark never loses sight of the big picture of a claim. Although he has an impressive track record of undeniable results, he never loses the practical perspective and evaluates matters from a legal, as well as economic perspective. 

Mark has been a featured speaker at the National Conference of Insurance Guaranty Funds and at the New Jersey State Bar Association on coverage and insurance solvency issues. He has also spoken before the Professional Liability Underwriting Society on legal malpractice issues.

Upon graduation from law school, Mark clerked for The Honorable Clarkson Fisher, Chief Judge of the United States District Court for the District of New Jersey. Mark was also appointed by the Supreme Court of New Jersey to the District XA Ethics Committee, where he served on the committee for four years, acting as the Chair in 2010.
