Alondra then moved to Utah, where she performed on stage in public for the first time. In the month of March 2009, she had the fortune to be invited to partake in a Telethon sponsored by TV Azteca America network for the benefit of the victims of the earthquake in Chile and Haiti. She would later participate in several events for the American Red Cross, American Cancer Society, among other charitable organizations. She has also participated in several television shows as a singing contestant including "Tengo Talento Mucho Talento".
