Revere Police K-9 Officer Mike Mason and his partner, Walsh, put on an impressive demonstration last Thursday for the summer program at the Whelan School, answering loads of questions for the curious grade schoolers. Walsh was funded by the Department of Homeland Security and has been with the RPD for three years. Mason displayed Walsh’s impressive set of skills, including his ability to follow commands absolutely. The summer program at the Whelan is funded by a state grant and runs through August. The free program for 3rd and 4th graders is co-run by Beth Delaney – a district math coach – and concentrates on math and science. The school was eligible for the grant because it participates in the state’s Extended Learning Time grant program.
