SUMMIT, NJ – Three members of the Summit Police Department were promoted Wednesday during a ceremony officiated by Summit Mayor Nora Radest in Summit’s Common Council chamber.

The ceremony saw Lieutenant Michael Treiber promoted to the rank of Captain; Sergeant Christopher Medina promoted to the rank of Lieutenant and Officer Jeffrey Peer promoted to the rank of Sergeant.

A Florham Park native, Treiber studied Criminal Justice at Seton Hall University and began his career with the Summit Police Department in April 2000 as part of the Patrol Bureau, according to a biography provided by city officials. He was later assigned to the Detective Bureau from 2006 to 2012, when he was promoted to the rank of Sergeant. In 2018, he was promoted again, this time to the rank of Lieutenant. Treiber has been assigned to the Auto Theft Task Force, the Newark Headlight Task Force, and the Union County Narcotics Task Force. He has received multiple accolades for his service, including the Chief’s Meritorious Service Award and several exemplary performance notices.

Medina grew up in New Providence and attended Miami University of Ohio, where he studied Business Administration/Accounting, city officials said. He joined the Summit Police Department in 2006 as a patrol officer and became certified as a Field Training Officer where he taught departmental policies and procedures to newly hired officers. Medina was promoted to the rank of Sergeant in 2021 in the Patrol Bureau after an assignment in the Detective Bureau.

“During this time, he was instrumental in assisting Captain Ryan Peters with achieving accreditation status for the Summit Police Department from the New Jersey State Association of Chiefs of Police,” the city wrote in a statement.

Medina has received multiple distinguished services awards, two lifesaving awards, and one Chief’s Award.

He attended the John H. Stamler Police Academy and was sworn in as an officer with the Summit Police Department in April 2000. He was assigned to the Patrol Bureau and appointed to the position of Field Training Officer. Peer was assigned to the Union County Emergency Response Team (UCERT) in 2009, where officers are hand-selected and trained for intensive, emergency response situations including high-risk search and arrest warrants and hostage situations. He has received four Honorable Service Awards, a Chief’s Award, and multiple commendation letters from his supervisors, the city said.
