The Hollidays serve with Mission to the World and Isaiah 55 Ministries at the US/Mexico border. With Isaiah 55 in Reynosa, Tim uses his skills in computers and technology to serve both the administrative side of the mission and also to offer those skills in vocational ministry among deaf students and the neighborhood community. Kristy uses her background in ESL to serve in the community around the Isaiah 55 ministries. Mostly, their heart is to serve as support to those around them in whatever capacity they can.
