GRÁINNE O’NEILL

Ms. O’Neill has a B.A. in Mathematics and Computer Science from Cornell University, and a  J.D. from Columbia Law School.  Upon graduation from law school, she worked as a Staff Attorney at Orleans Public Defenders, where she represented clients from arrest to plea, disposition, or acquittal.  As a Staff Attorney, and then Legal Systems and Technology Director she developed technology tools for her office.  She briefly left direct client representation for a fellowship at the Charles Hamilton Houston Institute at Harvard Law School, where she developed MyGideon, a knowledge management system used by criminal defense attorneys nationwide. Ms. O’Neill then returned to her true passion: representing people accused of crimes, in and around New York City.  She completed the Southern District of New York’s CJA Mentorship Program and serves on the Southern District of New York and Eastern District of New York’s CJA panels. Ms. O’Neill is on the board of the New York State Association of Criminal Defense Lawyers (NYSACDL).

Ms. O’Neill secured a full acquittal in the Southern District of New York, United States v. Kenneth Charlton, 18 Cr. 30 (PAC) and was honored to walk Mr. Charlton out of prison and into a local pub.

Using a novel legal argument, that the BOP lockdown was exacerbating pre-existing mental health conditions, Ms. O’Neill achieved the compassionate release of her client in United States v. Louis Pina, 18 Cr. 179 (JSR).
