The Rochester Senior Center has earned accreditation from the National Council on Aging’s National Institute of Senior Centers, said the center’s director, Sharon Lally. The accreditation came after a yearlong application process, she said, which included the work of 73 volunteers on nine committees on the self-assessment component of the application. Each committee represented a different standard reviewed in the process, she said, adding that getting accreditation is an honor, not unlike the Good Housekeeping Seal of Approval. “It means you’ve done everything you could to meet the needs and interests of the people in your community,” she said. Lally added that the senior center serves people of all ages and was used an emergency shelter for residents who were without power during the February blizzard.
