Law Offices of Kevin T. Grennan, PLLC NYC and LI law firm handling personal injury, medical malpractice and nursing home negligence. Offices: Garden City and 420 Lexington Ave. Mr. Degree from St.

For twenty five years, attorney Kevin Grennan has been helping clients on Long Island and in New York City, to recover money damages for personal injuries sustained in accidents and as a result of medical negligence. We also handle civil rights, employment and commercial litigation. When you entrust your personal injury matter to us, you will deal directly with Kevin Grennan, the founding member o

f the firm, as well as our legal support staff. We pride ourselves on being accessible and responsive to our clients. For new client matters and true emergency situations, we are available 24 hours a day, 7 days a week. Because many of our clients are unable to travel to our office as a result of their catastrophic injuries, Mr. Grennan will personally travel to you or your loved one's home or hospital room for a free initial consultation. We zealously represent our clients, and, although most cases settle prior to trial, we prepare every case that we accept as if it were going to trial, from the outset. We believe that money recoveries are maximized when our adversaries know that we have exhaustively and diligently prepared our case as ready for trial. We pride ourselves on the fact that a substantial percentage of our cases are referred to us by other attorneys who feel that our expertise could better serve them and their clients. Once a case is referred to us, both the attorney and client receive our high level of responsiveness and professionalism. Grennan began his legal career working in the downtown Manhattan in-house counsel office of a major insurance carrier. In addition, before establishing his firm, he practiced for several years as an associate with a Long Island law firm specializing in both the defense and prosecution of personal injury and medical malpractice claims, and commercial and insurance litigation. Grennan received his B.A. in Economics, cm laude, from St. John's University in 1985 and received his J.D. John's University School of Law in 1995. He is a member of the following associations:

The American Association for Justice
New York State Trial Lawyers Association
New York State Academy of Trial Lawyers
Nassau County Bar Association
Suffolk County Bar Association
Omicron Delta Epsilon, International Economics Honor Society

Mr. Grennan also sits on the Plaintiff's roundtable of the Nassau County Bar Association.
