Carolyn Margolies

Carolyn’s 17 years of trial advocacy has been earned in civil and criminal courtrooms throughout New York State and, most recently, Florida Courts.  She began her legal career representing the student body of SUNY New Paltz and won a Federal Court Injunction to bar the local board of elections from rejecting student voter registrations resulting in a change in legislation that now permits students to choose their dormitory as a domiciliary for voting purposes, and thereby grants student access to local politics.

As a Senior Assistant District Attorney in Orange County, NY, Carolyn worked with the criminal defense bar to facilitate treatment for those charged with driving under the influence and assisted in the State’s Drug Court initiative.  Immediately following the September 11 attacks, Carolyn became an active member of T.L.C. (Trial Lawyers Care); an organization formed to provide pro bono legal representation to the families of World Trade Center Victims.

As a lead trial attorney at Cheven, Keely & Hatzis, Carolyn had a record number of successful verdicts on behalf of plaintiffs and defendants throughout in the five boroughs of New York City, as well as Albany, Putnam, Westchester, Suffolk and Nassau Counties, in matters of medical malpractice, negligence, labor law and contract litigation.  Her aggressive representation of litigants and her many successful verdicts, have been reported on in numerous publications, including the New York Law Journal.

Most recently, Carolyn served as President/CEO YWCA of the Middle Rio Grande in Albuquerque, New Mexico, where she practiced Not for Profit Law and handled a 3.2 million dollar budget, strategic planning, team building, community relations, grant writing and development.  She partnered with other non-profits, local schools, colleges and corporations and insured win/win outcomes in collaborative branding and community building.
