Dominican Sisters of St. Cecilia are a group of nice ladies who have dedicated their lives to serving God and the Church. They live together in a special place called a convent, where they pray, study, and work to help others. They wear special clothes called habits and have different jobs within the community, such as teaching in schools and taking care of the poor and sick. They also follow some really important rules, like always being kind to others and helping those in need. Overall, they are a great example of how we can serve God by serving others.
