Description

I spent years working homicide in Manhattan South. Now I make it real on screen. As a police technical advisor on Law & Order: Organized Crime, Elementary, and other major series, I bring authentic investigative detail—interrogations, crime scenes, arrests, and command decisions—into film and television. I help productions get it right without slowing the day, working directly with writers, directors, and actors to ground every scene in reality. If it feels real, it holds. If it doesn’t, the audience knows.
