Car Accident Claims
Our firm specializes in representing car accident victims seeking compensation for injuries and property damage. We prove negligence through evidence like police reports and witness testimony while countering insurance company tactics. Our experience with New York's no-fault insurance system ensures clients receive rightful benefits and pursue third-party claims when applicable. We handle all case aspects from initial consultation through trial if necessary.
Truck Accident Litigation
We represent victims of tractor-trailer and big rig collisions involving catastrophic injuries. Our team investigates multiple liability sources including drivers, trucking companies, and maintenance providers while navigating federal transportation regulations. We work with accident reconstruction experts to establish fault and secure compensation for medical expenses, lost income, and long-term care needs resulting from these devastating crashes.
Medical Malpractice
Our attorneys handle complex medical malpractice cases involving surgical errors, misdiagnoses, and birth injuries. We collaborate with medical experts to prove standard of care violations while countering hospital defense strategies. The firm secures compensation for additional medical treatments, lost earning capacity, and pain and suffering caused by healthcare provider negligence.
Construction Accidents
We advocate for construction workers injured from falls, equipment failures, and unsafe site conditions. Our experience with New York Labor Law 240 ensures proper application of strict liability provisions while pursuing third-party claims against contractors and equipment manufacturers. We secure compensation covering medical treatment, wage replacement, and permanent disability impacts.
Wrongful Death Claims
Our firm represents families seeking justice for loved ones lost to negligence. We pursue compensation for funeral expenses, lost financial support, and emotional damages while navigating complex legal requirements under New York Estates, Powers, and Trusts Law. Our compassionate approach balances aggressive litigation with family support during difficult times.
