Clifford M. Ader

Assistant Professor, Criminal Justice

Technology Center, Room 8242


Clifford M. Ader rejoined the RCC faculty in 2011. He previously taught as an adjunct at the College from 1996-1999, and also served as an adjunct at St. Thomas Aquinas College and Westchester Community College.

Ader enriches instruction by bringing his experiences in the New York Police Department to students in the classroom, illustrating theories with real-world examples. During his 20 years with the NYPD, Ader was one of only 100 members citywide on the Hostage Negotiation Team, was a detective on the Homicide Task Force, and a detective investigator in the Narcotics Division within the Organized Crime Control Bureau, among other assignments. He provided training for new officers and co-wrote the current NYPD Criminal Investigation Course.

He has been a certified New York State Police Instructor since 2008, and also lectures at the Rockland County Police Academy.

Ader attended RCC, then transferred to Pace University, completing a bachelor’s in Criminal Justice in 1989. He cites the seamlessness of the transfer, the excellent foundation he received at RCC, and the tremendous value the College offers students. He continued his education at Iona College, earning an MS in Criminal Justice in 1996, and has been accepted as a doctoral candidate at Capella University.
