The Law Office of Zachary Margulis-Ohnuma is a solo law practice in New York City defending complex state and federal criminal cases. Matters range from white-collar crime such as insurance and health care fraud, to defending sex crimes such as possession of child pornography. We pride ourselves on listening to clients, aggressively litigating (or negotiating) each case, and never being afraid to go to trial. We are located on Madison Avenue in midtown Manhattan and practice in the Second Circuit Court of Appeals, the U.S. District Courts for the Southern and Eastern Districts of New York, and the state trial and appeals courts throughout downstate New York.
