Proud to Be From Queens
Sean is a Queens guy through and through. He grew up in Queens, attended high school here, and began his legal career serving the people of Queens as a prosecutor. Long before becoming a lawyer, Sean worked as an Emergency Medical Technician serving the Jamaica Hospital community. As an EMT, he responded to emergencies throughout Southern Queens, helping people during some of the most difficult moments of their lives. His dedication earned him multiple citations for outstanding service.
That experience shaped the attorney he would later become. He understands what it means to work hard for a living, support a family, and worry about what tomorrow will bring.
