Through the implementation of the Narcan and One Voice programs in Mercer County, he is collaborating with law enforcement, health care and community organizations to provide first responders with the overdose antidote, make treatment and recovery resources available to addicts and their families, and host community forums in an effort to combat this epidemic through education, awareness, prevention and treatment.

Mr. Onofri began his career with the law firm of McCarthy and Schatzman, P.A., where he worked as a litigation associate for six years. He also served as the deputy Mercer County counsel and an assistant municipal prosecutor for the city of Trenton before joining the Mercer County Prosecutor’s Office in May 1998.
