Allen Aldenberg


Allen Aldenberg is the Police Chief in Manchester, NH, the state’s largest city and police department. Aldenberg has worked in law enforcement for 27 years, serving with the Essex County Sheriff’s Department in Massachusetts and the Goffstown Police Department prior to joining the Manchester department in 2003.


During his tenure in Manchester, Aldenberg has served as a patrol officer, field training officer, K9 officer, and as an investigator within the Detective Unit. Following his promotion to sergeant in 2013, he was assigned as a patrol supervisor and later served as the director of the Training Unit. He was promoted to lieutenant in 2017 and has been a member of the SWAT Team since 2011.


He was awarded the department’s Life Saving Medal in 2011 for his efforts in preventing a suicidal person from jumping from the ledge of a parking garage. And in 2016 he was awarded the Meritorious Service Medal for negotiating the surrender of an armed man.

Aldenberg established an anti-crime unit within the patrol division “as part of the Project Safe Neighborhood initiative,” said Mayor Craig. “This played a critical role in the 11 arrests made on October 2 in the alley south of Auburn Street.”


Aldenberg has served with the Massachusetts Army National Guard for 26 years. He holds the rank of colonel and is the brigade commander for the 79th Troop Command-Homeland Security. Since 9/11, he has been deployed to Pakistan, Uzbekistan, Afghanistan and Iraq in support of Operation Enduring Freedom and Operation Iraqi Freedom. He received the Bronze Star for his service in Iraq from 2009–10.


Aldenberg holds a Bachelor of Arts degree in criminal justice and a Master’s degree in justice administration from Norwich University in Vermont. In July 2017, he graduated from the U.S. Army War College with a Master of Strategic Studies degree.
