Areas of Practice

car accidents

When you have been involved in a car or truck accident, it is vital that you protect your rights as quickly as possible. You may be contacted by insurance companies trying to “low ball” you on your case. You also might not know that you may be entitled to free medical treatment. That’s where we come in, and advocate for your rights and counsel you through these confusing times.

boating and jet ski accidents

During the summer months, recreational boating areas can get highly congested with boaters, jet skiers, and fishermen. The likelihood of accidents are high during this time, especially when alcohol and multiple people are involved. We can help guide you through this process and make sure you are advised on the best course of action.

slip/trip and fall accidents

If you have been injured on the property of another and the condition of the property was a factor to that injury, the owner or manager of that property may be responsible for your injuries. Property owners and managers have a duty to maintain and, if necessary, repair the property to ensure that it is safe. If you are injured as a result of the negligence of a property owner or manager, we can work to build a case against them, and hold them responsible.

construction site accidents

It is common in the construction industry for workers to be working with many different contractors that perform different specialized jobs at the same site. As a result, accident cases can usually be sued as personal injury claims, with or without a workers’ compensation claim, and certain contractors can be held responsible.

dog bites

There are many dog owners on Long Island and New York City. Most of these owners are responsible with their dogs. However, even the most responsible owner cannot control their dog, especially if it is a dog with vicious or aggressive tendencies. Whether the dog was beyond the control of their owner or the owner was being irresponsible, if you were injured as a result of this, we may be able to hold the owner accountable.

motorcycle accidents

Motorcycle accidents tend to produce severe injuries due to the lack of protection that a motorcycle affords to the driver. These injuries require very expensive hospital care and typically involve a long and difficult recovery process. We will make sure that you have access to the medical and financial resources that you will need to be able to begin your road to recovery.


Being a lawyer is not merely a vocation. It is a public trust, and each of us has an obligation to give back to our communities.
