Our attorneys’ reputation for hard work and top-quality legal assistance has spread throughout the local Syracuse area and New York State since 1987. To us, this practicing of legal excellence means many things: It means responsive, attentive treatment of clients; it means proactive, detail-oriented work; and it means selecting only a few cases and giving each one our best efforts rather than taking too many to handle thoroughly.

In over 90 years of combined experience, our attorneys have been involved in hundreds of trials and have negotiated hundreds of out-of-court settlements. Our law firm also does work outside the realm of litigation, giving valuable legal advice and preparing legal arrangements that prevent future disputes.

We work hard for people and businesses throughout the Central New York region - including Onondaga and Madison County locales like Syracuse, DeWitt, Liverpool, North Syracuse, and Cazenovia - and the state of New York.
