About me



Michael S. Lamonsoff Esq. is the founder and owner of the Law Offices of Michael S. Lamonsoff, PLLC, one of the largest firms in New York concentrating in Personal Injury, Construction Accidents, Police Misconduct, Slips and Falls and Medical Malpractice. 

In just two decades, Mr. Lamonsoff has built one of New York’s largest law firms for both personal injury and police and prosecutorial abuse cases. His reputation as a leading personal injury lawyer is fueled by a track record that includes some of the largest personal injury verdicts and settlements in New York State history.

Mr. Lamonsoff was quoted in New York Magazine as saying, “I love to win, and my clients love me for it.”  

Practice Areas:

Personal Injury: The firm concentrates its practice in the representation victims of accidents including construction accidents, whether they are falls from a ladder or scaffolding or even a crane accident. We also represent victims of car accidents, truck accidents, slips and falls in a building or on the sidewalk. 

Police Misconduct:  The firm also concentrates its representation of victims of police brutality and police excessive force, false arrest and police shootings as well as other incidents of misconduct on the part of police

Medical Malpractice: The firm is equipped to represent victims of medical malpractice, including negligence, birth injuries, pharmacy negligence, and many other instances of malpractice.


The Philosophy

While the vast majority of cases settle, Mr. Lamonsoff believes in preparing every case for trial.  “Our philosophy is that the highest settlements are awarded when the defendant is afraid of the consequences of a trial against a highly prepared law firm.  We are that law firm.”


Press and Accolades:

The Law Offices of Michael S. Lamonsoff was recently featured In New York Magazine’s Legal issue, recognized as one of the Top Litigators in New York for attaining some of New York’s highest award.  In a matter of months the firm secured a $4.75 million settlement two days before trial on behalf of a man who served 18 years in prison for a murder he did not commit; this result stands as the highest figure in state history for a wrongful conviction.  In addition, the firm obtained one of the highest verdicts in the state—a $5.5 million award—for a construction worker who suffered spinal injuries when a wood bracing collapsed while he was exiting a trench as well as a $4.75 million settlement during jury selection for another injured construction worker.

Mr. Lamonsoff has attained the status of an authority in his field, and is often called upon by local, national, and international news outlets to provide commentary on pressing legal matters and the high-profile cases he litigates. His peers, meanwhile, have named him to Super Lawyers and inducted him into the prestigious Million Dollar and Multi-Million Dollar Advocates Forum. And as a leader in the legal community, he has served on the New York State Trial Lawyers’ Association’s Board of Directors, and is currently the highest-rated NYC personal injury attorney on Avvo.

    No lawyer in NYC works harder then Michael Lamonsoff. He truly cares about his clients and obtains very large settlements on matters other attorneys reject. I've had the pleasure of working with Michael and other attorneys at his office on mutual cases involving workers' compensation cases and he always seems to find the time to help all of his clients.
