While attending a Muscular Dystrophy Association banquet at age nine, Foster asked if he could address the audience. "I was anxious because I had never done it before, but when I got up there I didn't want to stop," he recalled. To the surprise of his parents, Foster demonstrated a flair for communication; this in turn led to his choice as a national MDA Goodwill Ambassador for two consecutive years. In this role, Foster appeared on the annual MDA telethon, by then called the MDA Show of Strength, visited numerous MDA corporate and business sponsors, and met many celebrities. Foster also dealt frequently with the media and appeared in various MDA national promotional materials, including video public service announcements and MDA "shamrocks." He has also served as MDA Goodwill Ambassador for the Charlotte, North Carolina, area. "My favorite part of the job," explained Foster of his Goodwill Ambassador role, "is meeting new people and being able to thank the sponsors and supporters in person who help make an impact in the lives of people just like me. Every dollar and every cent really does count, and my mission is to have fun while spreading the word about MDA and its mission to help people living with muscle disease." "Most kids my age don't come across opportunities like the ones I've had...," he also observed. "I've experienced so many new things and met wonderful people along the way. I just want to keep speaking from my heart and doing what I love most to inspire people to support a cause that is close to me and my family."
