Experienced criminal defense attorney, Gabriel J. De Matteo, heads the firm, The Law Offices of Gabriel J. De Matteo, in Lincolnwood, Illinois. Mr. De Matteo has been involved in the legal field for more than 30 years.
While still enrolled in The John Marshall Law School in Chicago in 1985, De Matteo worked as a law clerk for the firm of Walsh and Neville in downtown Chicago.

He was honored to have been selected by State's Attorney Richard M. Daley to serve as a Cook County Assistant State’s Attorney.
During his long career as an Assistant State’s Attorney, De Matteo tried hundreds of cases, including more than 40 felony jury trials. The cases ranged in seriousness and complexity from drug cases to first-degree murder. In 1997, he was promoted to a felony preliminary hearing supervisory position. In that role, De Matteo supervised other prosecutors and was responsible for the beginning stages of thousands of criminal prosecutions each year. In 2003, De Matteo left his position and began private practice, and has since helped hundreds of clients navigate through the complexities of the justice system.
