Prior to attending college, I volunteered as a webmaster at a local program of Special Olympics in Nagano, Japan from 2001 through 2005. Between 2003 through 2005, I worked for the game organizing committees of the 2004 Special Olympics Nippon National Winter Games and the 2005 Special Olympics World Winter Games Nagano, Japan to host youth summits and to launch Special Olympics' K-12 education programs in Japan. I received the Prudential Spirit of Community Award for my work in Special Olympics Nippon Nagano, and my work in the K-12 program was widely recognized by the local media.
