The Firm

Spiegel Leffler is a boutique law firm specializing in the defense of physicians, dentists, oral surgeons, nursing homes and other healthcare professionals, in malpractice lawsuits and disciplinary complaints by State authorities.

We are a team of dedicated, creative thinkers who thrive off the challenges of litigation and thoroughly enjoy what we do.

Partners William Spiegel and Marc Leffler have been trying cases for many years, and have won verdicts in favor of their clients on even the most difficult cases. Both have been recognized by Martindale-Hubbel with a rating of "AV Preeminent," that organization’s highest peer review rating achievable, based on legal ability and ethical standards.


We are a small firm consisting of ten seasoned attorneys: two partners, one managing partner, three associates and four attorneys who work on an “of counsel” basis. We also employ experienced paralegal and support staff. Unlike large firms, we will never de-prioritize you for another client or treat you as one of a hundred. You are guaranteed our undivided attention.

We focus on defense, but can represent you at any stage of your career. Our attorneys are experienced in negligence and malpractice claims, capable of building an aggressive defense against the most complex litigation. Outside of defense, we offer legal services to support you in everything from partnership agreements to insurance audits to the sale of your practice.

We have offices in New York, New Jersey and Connecticut, in close proximity to the State and Federal Courts. You can access our services in Connecticut, New Jersey, in all five New York City boroughs, as well as the suburban, Long Island and upstate counties.

We make sure to keep you apprised of the status of your case. The partners direct the litigation and review all pertinent documentation and records with the ultimate goal of preparing a case for trial.
