Chief's Message

Thank you for visiting the Colerain Police Department's official website. I have no doubt that as you browse oChief Mark C. Denneyur site, you will understand why it is my honor to lead one of the most progressive, innovative and dedicated police agencies in the area.

Commission on Accreditation of Law Enforcement Agencies (CALEA)

In August of 2017, the Colerain Police Department had our fifth on-site from the Commission on Accreditation of Law Enforcement Agencies (CALEA). CALEA is an accrediting body that ensures a police agency is operating under the “best standards” in law enforcement. This is a rigorous, voluntary process that less than 10% of the 18,000 law enforcement agencies in the United States undergo. As a result of the August on-site assessment, the Colerain Police Department was awarded the Advanced Gold Standard Re-Accreditation. For the 3rd cycle in a row, the Commission also elected to honor the Police Department with the rare “With Excellence” honor. 

This distinction is for police departments who, in the words of the Commission, are the “Best of the Best.” The Commission will return to Colerain Township in August 2021 to re-evaluate our progress and ensure we continue to meet their demanding standards.

Coffee with a Cop

Connecting with the community is a priority for me, The “Coffee with a Cop” program began in January 2014. and allows citizens to meet with me on a monthly basis to discuss issues impacting their neighborhood and families. The program was such a success, we decided to expand it, re-naming it to “Coffee with the Chiefs.” On the third Friday of every month, I am joined by Colerain Fire Chief Frank Cook and we look forward to meeting new friends and answering questions. Check the "Coffee with the Chiefs (JPG)" for our schedule.


Chief of Police BadgeI am proud of our accomplishments and excited about our future. The Colerain Police Department employs smart, capable and caring officers who continue to push the envelope and make our organization and themselves better. A chief cannot ask for more than that!

The Colerain Police Department will continue to be accountable to our citizens and transparent in our operations. We will continue to be financially responsible while providing the very best police service to a best in class community. We thank you for your continued support and it is our honor to serve you.
