Twenty-one Buffalo police cadets were sworn in Friday to begin six months of training before hitting the streets as patrol officers.

Mayor Byron W. Brown and Police Commissioner Daniel Derenda presided at the swearing-in ceremony as dozens of the cadets’ family members proudly watched in the Training Academy at Buffalo Police Headquarters.

“You are entering a proud tradition. You’re joining one of the finest police departments in the nation,” Brown said, explaining that public safety is playing a major role in helping attract new commercial and residential development to the city. “Overall crime in the city has been decreasing since 2006, and one of the factors that is looked at when decisions are made on whether to invest in a region is public safety,” Brown said. “The more successful the Buffalo Police Department is, the more continued investment there will be in the city.”

Derenda told the recruits they can expect to be “worked hard” over the next six months as they receive instruction at the Erie County Central Police Services Law Enforcement Training Academy and that he looked forward to seeing them at the completion of the training.

Taking the oath were:

Mark D. Ambellan, Andrea A. Anderson, John R. Bannister, Joseph J. Christopher, Agnieszka Dembinska, Kyma J. Dickinson, Robert J. Felschow III, Nicholas R. Herbert, Michael A. Kausch, David F. Kimmins, Anthony R. Kozlowski and David M. Kubiak.

Also, Todd C. McAlister, Patrick J. McDonald, William J. Moretti, Michael J. Norwood Jr., Sharese L. Saleh, Thomas P. Sullivan, Courtney A. Tripp, Jenny M. Velez and Gaisha B. Wilson.
