Michael S. Lamonsoff is the founding partner of MSL (Law Offices of Michael S. Lamonsoff PLLC) in New York, New York. He has earned the nickname of “The Bull” because of his relentless and forceful approach in fighting for his clients’ rights. His passionate “no holds barred” representation has yielded some of the highest settlements and verdicts.

Michael Lamonsoff is renowned for representing clients in some of the highest-profile personal injury, construction accidents and civil rights cases. While the vast majority of cases settle, Mr. Lamonsoff believes in preparing every case for trial.

“The insurance companies are afraid to go to trial. They want to control the process. They want to control the amount of compensation our clients get for their injuries. They know that once the case goes to trial, they have lost this control to a jury. A jury is made of people just like you and others in the community where you live. They are far more sympathetic to our clients’ plight than multi-national insurance corporations. That is why, the closer we come to trial, the more money they will offer. I have assembled a special team of highly aggressive attorneys, paralegals, experts, and paraprofessionals to defeat the insurance companies at their own game.”
