About Me

MICHAEL S. LAMONSOFF, ESQ., is the founder and owner of the Law Offices of Michael S. Lamonsoff, PLLC. He is admitted to practice in all State Courts of New York and the Federal District Courts for the Southern and Eastern Districts of New York.  He is a member of the Board of Directors of the New York State Trial Lawyers Association, serves on its Ethics Committee and is a past Subcommittee Chairman. He is a member of the New York State Bar Association, Association of Trial Lawyers of America and the New York County Lawyer's Association.

Mr. Lamonsoff graduated from the University of Arizona with dual degrees as a Bachelor of Science and Bachelor of Arts in 1984. Thereafter, he was accepted into the prestigious postgraduate studies program at Columbia University. As one of the graduate program's most accomplished students, he was awarded a meritorious scholarship for his academic achievements. While there, he served in various capacities in student politics. He also served as the Editor of the student newspaper. At Columbia, he was awarded a Masters of Arts and Masters of Education. 

Following his graduation, he attended the Benjamin N. Cardozo School of Law. During law school, he was selected by the Honorable Justice Simone E. Chrein, Chief Magistrate of the Federal Court for the Eastern District of New York, to serve as his Student Law Clerk Intern. Thereafter, he was selected as a Student Law Clerk Intern to the United States Attorney's Office for the Southern District of New York, Civil Division, serving under the then acting United States Attorney, Rudolph Guliani. Subsequently, Mr. Lamonsoff was hired as a Law Clerk specializing in drafting appeals for an insurance defense firm.

Upon his graduation from law school, he was hired as a staff attorney/litigator by the law firm of Garfinkel & Lesman, in house counsel to one of America's largest insurance companies, the American International Group. After serving with distinction at Garfinkel & Lesman, Mr. Lamonsoff was offered and accepted a partnership with a large plaintiff's personal injury law firm in New York City. In 1995, Mr. Lamonsoff left that firm and founded the Law Offices of Michael S. Lamonsoff, PLLC.. As a result of his aggressive and results-based litigation style, the Law Offices of Michael S. Lamonsoff, PLLC. has become one of the largest plaintiff personal injury law firms in the country specializing in the representation of accident victims.

Mr. Lamonsoff has made numerous television appearances and has been interviewed and widely quoted in the print press regarding high profile cases handled by the firm. He has appeared on CNN, MSNBC, ABC, NBC, MY9, NY1, CBS, radio and cable television programs. In addition, Mr. Lamonsoff was asked to appear on a number of episodes of the legal television show “The Lie Detector”. He was also asked to appear on “The People’s Court”. These requests he had to refuse because of his time constraints in running one of the largest Personal Injury/Medical Malpractice firms in the country.
