For many families, grandparents represent generations of tradition and cultural cohesion. This week on WGBY’s bilingual program Presencia, elders are given the spotlight. First, hear from Westfield residents Pedro Rivera Moran and Mary Fernández with grandparenting advice and insight. Then, learn of Doña Ana, a North End grandmother who made a lasting impact. Visit Costa del Sol of Hartford and see how the restaurant keeps Spanish and Mediterranean culinary traditions alive. Finally, enjoy a dance performance by Amapolas, a 55+ group from the Holyoke Senior Center.
