About Kevin

Learn Kevin’s areas of practice.

For 20 years, I have 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, as well as representing parties in business disputes.

When you entrust your personal injury matter to my firm, you will deal directly with me, the founding member of 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, I am 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, I 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 significant 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.

I began my legal career working in the downtown Manhattan in-house counsel office of a major insurance carrier. In addition, before establishing my firm, I 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.

I received my B.A. in Economics, cum laude, from St. John's University, and received my J.D. Degree from St. John's University School of Law in 1995. I am 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

I also sit on the Plaintiff's roundtable of the Nassau County Bar Association.

In addition, I am admitted to practice in all New York State Courts and in the Federal Courts for the Southern District and Eastern District of New York, as well as the Federal Second Circuit Court of Appeals.

OUTSTANDING ATTORNEY! I would leave 250,000 STARS if I could!
Kevin was referred to me by a close friend who said, "she strongly & highly recommends him, he was able to get her a large sum of money by fighting hard!" He met with me immediately, sent out an investigator to take pictures of the accident scene. Kevin's professionalism and client first atmosphere are amazing. He makes sure his staff follows his lead. From promptly returning phone calls, to answering all questions patiently. His reputation is of an attorney who does not back down, his high standards makes him a "SUPER LAWYER!" I can not THANK him enough for fighting so hard, for the best outcome for me. He is truly the BEST attorney!!

Honest and respectable
Through a recommendation, I contacted Mr. Grennan to give me advice on how to handle my daughter's accident case. He was completely honest on different scenarios. The entire process took 3 years and I kept Mr. Grennan updated on the progress. I would've definitely hired him but our insurance company provided attorneys for us. Mr. Grennan was professional and knowledgable. He treated my daughter and I with respect and showed genuine concern.
