Litigation & Dispute Resolution

Our litigation practice is among the largest and most highly regarded in the Northeast. More than 70 years of courtroom success have cemented our reputation as leaders in trial and appellate advocacy. For our clients – who range from multi-national corporations to locally-owned businesses and individuals – the size and diversity of our litigation practice means a legal team matched to your needs and goals. In every case we handle, no matter how complex, the client remains the focus. You always know the attorney responsible for your case, you are consulted at every turn, and you are always kept fully informed.

Three components drive our success: trial experience, attention to detail and attention to cost. We are highly experienced in all phases of civil litigation and appeals in state and federal courts, as well as in alternative dispute resolution and hearings before government agencies. Our experience not only enhances our courtroom proficiency, it also enables us to work more efficiently. We are committed to ongoing and timely communication with our clients. That communication is enhanced by our policy of assigning a coordinating attorney to every case, who monitors all proceedings and serves as liaison to the client.

The scope of our litigation practice is broad and extends to business and commercial cases, civil rights, employment, insurance coverage and defense, products liability and toxic torts, professional liability, torts and general litigation. We represent clients in courts and adjudicatory forums throughout the United States and internationally. Whatever type of litigation you face, our attorneys have the experience and focus to pursue zealously the outcome you aim for.
