Zoli and Csilla Schuller have three children: Abigél, Dániel and Naomi. Zoli was raised in a non-Christian family. While he was in the army, God called out to him through a fellow believing soldier. After receiving Christ in his life, he began to serve as a youth leader and met his future wife, Csilla.

After they got married, they continued to serve together as youth leaders, according to their calling from God. They are now both serving full time with YFC Romania. “We like to serve God in full time mission among young people, because we strongly believe that they need to know Christ and have Him influence their lives.”
