A Message From Our President, Raymond A. Tierney
was sworn in as DAASNY President.
As incoming DAASNY President, I pledge to serve as a voice for all New York prosecutors from across the state from large counties to small. Rather than focus on issues that might only be a priority in my county, I want to hear from our prosecutors around the state and tackle issues that we all face in common. I intend to be an advocate in Albany on behalf of all prosecutor’s offices in New York. Being a prosecutor is not an easy job, but it is our duty to bring justice and ensure public safety to the best of our abilities. My job as DAASNY President is to provide support and be your voice as we all work to keep New York safe.
