John N. Post

John is a Marine, having spent three years as a JAG Officer in the Marine Corps, trying courts-martial and advising Marine Commands in the U.S. and the Republic of Vietnam, where he served in Danang during the TET Offensive. On his release from active duty, he founded the law firm which has grown to become Post Polak Goodsell & Strauchler. He was the Managing Partner until 2008, when he resigned in order to devote his full attention to the firm’s clients.

A man in a suit and red tie.


John Post’s practice focuses on substantial litigation and transactional matters for both private and public sector clients. Among his notable accomplishments, he has negotiated contracts for a head coach in the NFL, tried a nationally televised divorce case against a former governor of the State of New Jersey, and has been the attorney for the Borough of Mountainside for 43 years, on whose behalf he has conducted ground-breaking litigation against other local governments, regional authorities and the State of New Jersey.
Most recently, in an effort which the Court Appointed Special Master, Retired Judge Eugene Serpentelli, described as “outstanding,” and which demonstrated remarkable prescience, John obtained a Judgment of Repose through the courts which gave Mountainside immunity from Mt. Laurel suits for ten years. Six months later, the New Jersey Supreme Court acknowledged COAH’s administrative ineffectiveness and made judgments obtained through the courts the exclusive vehicle for municipalities seeking immunity from Mt. Laurel lawsuits.
John has received an AV Preeminent rating by Martindale.
