Consulting & Expert Review Services
Accurate sentencing isn’t optional — it’s essential.
With more than 45 years of professional experience, Terence Davidson brings unmatched expertise in criminal justice data systems and sentencing computation. He has worked extensively with New York’s defender organizations, courts, corrections professionals, and private attorneys to ensure that every sentence is calculated lawfully and every day served is counted correctly.
Mr. Davidson is the creator of Sentence Calculator, the first automated system built on Article 70 of the New York State Penal Law. His expertise has been adopted by the Legal Aid Society’s Decarceration Project and relied on by attorneys and administrators across the state to prevent unlawful over-detention and reduce administrative backlog.
