The Grennan Law Promise
At Grennan Law, our central responsibilities are:
Communication. Grennan Law is committed to keeping our clients informed about their legal options, as well as any setbacks or hurdles they might encounter. Our job is not to tell you what you want to hear; our job is to help you understand what is going on as we navigate the legal process.
Compassion. We understand that no two cases or clients are the same. This is why we carefully craft case themes to reflect your story: who you are, what you lost, and what it will take to make things right. As we fight to prove negligence and negotiate a fair settlement on your behalf or prepare for trial, we never lose the thread of your story.
Competence. After practicing law for nearly 30, Kevin Grennan and his team are here to win. We handle all discussions with insurance and co-counsel, apply relevant case law and statutes to your case, and call upon accident reports, eyewitness accounts, and personal testimony to establish liability and claim value. We are here to fight for every penny you are owed—and we are prepared to go to trial to do so.
Experience the Difference
Cost-Free Consultations. We offer free consultations on personal injury and malpractice cases and never collect money from you until we recover money on your behalf.
Seasoned Experience. With almost 30 years of experience, we understand what it takes to successfully advocate for our clients.

Frequently Asked Questions
What is a “personal injury”?
A “personal injury” simply refers to the harm experienced by the individual: physical, financial, emotional, relational, reputational, and so forth. Many injuries manifest in a number of ways.
Personal injury law covers everything from car accidents and construction injuries to assault to accidents and injuries resulting from defective products.
A personal injury lawyer is responsible for recovering compensation for people injured as the result of another person or party’s negligence. Our experienced trial lawyer specializes in motor vehicle accidents, construction accidents, premises liability, wrongful death, product liability, nursing home abuse, medical malpractice, and civil rights litigation.
Have you suffered a personal injury stemming from the negligence of someone else? You may be able to collect compensation. Call us at (516) 745 5490 (Long Island) or (212) 961 6976 (New York City).
How much does a Long Island personal injury attorney cost?
Grennan Law uses a contingency fee structure, which means that our payment is contingent on getting money for you. In New York, the contingency fee is computed before deduction for expenses and disbursements.
Is my case big enough to require a Long Island personal injury attorney?
Every injury—even a seemingly small one—has the potential to change a person’s life. No case is too small to benefit from the advice of a Long Island personal injury attorney.
Part of your lawyer’s job is determining the extent of your injuries, as well as who is responsible for paying your damages. This may require pursuing relevant insurance policies, researching the circumstances of the accident, and negotiating your file. We’re here to maximize your recovery while minimizing the stress involved with doing so.
For nearly 30 years, Grennan Law has been helping people just like you resolve their personal injury claims. Call us today to learn how we can help: (516) 745 5490 (Long Island) or (212) 961 6976 (New York City).

Yes! We believe that finding the right lawyer is important; that’s why Kevin is proud to provide free initial consultations.

Are you looking for a Long Island personal injury lawyer? The sooner you can retain an attorney, the easier it may be to resolve your claim. Call us today for your free consultation: (516) 745 5490 (Long Island) or (212) 961 6976 (New York City).
How long will it take to resolve my case?
The time it takes to resolve a personal injury claim will vary from case to case. Some cases can be handled within a few weeks; others may require much longer. Cases involving multiple lines of insurance or defendants and/or contested liability will take longer to resolve.
At Grennan Law, we don’t want our clients to wait one more day for the money they are owed. While we have limited control over how fast the defense responds to our demands—or how quickly the New York court system moves—we can, and will, be absolutely transparent with you throughout the process.
Will I have direct contact with the Long Island personal injury attorney handling my case?
Definitely. At Grennan Law, we’re here when you need us. Our mission is to provide legal services that not only meet or exceed your expectations but also provide a client experience that far surpasses what you would experience at other firms.
What does a Long Island personal injury lawyer do?
As a Long Island personal injury attorney, Grennan Law offers legal advice, support, and representation support in cases involving personal injury. Our attorney, legal staff, and experienced medical professionals take the time to fully understand our clients and their cases, presenting a multi-angled case perspective to maximize financial recovery.
How much is my New York personal injury case worth?
The value of your personal injury case can only be determined through settlement or verdict, but there are three strong indicators of what your claim may be worth:
- the defendant’s liability,
- your injuries and
- the present and expected costs of your injuries.
A strong case will generally have clear liability, obvious damages, and evidence to show the economic and non-economic costs. During the course of your lawsuit, you may encounter challenges to your story, testimony from paid witnesses whose job is to discredit your claim, and suggestions that you may be partially or wholly at fault for your injuries. Having a competent Long Island personal injury attorney is key to keeping your case value high in spite of these challenges.
Case value is not determined by the defendant’s reputation, financial standing, or insurance coverage.
If you would like to see what your case may be worth, the first step is to speak to a Long Island personal injury attorney. Call Grennan Law for a free consultation: (516) 745 5490 (Long Island) or (212) 961 6976 (New York City).
