Szczepan was born to a Christian family in Northwest Poland. His journey with youth ministry started at age 15 when he began co-leading his church’s youth group. For many years, he served and discipled young people, as well as led camps and other outreach events in Poland. In 2005, he moved to the United Kingdom where he planted a church for Polish immigrants with his wife Kamila and two friends. Szczepan was one of the main leaders of the church for eight years, and he also started a non-profit with his friend Przemek, focused on raising awareness about human trafficking. In 2015, Szczepan and his family returned to Poland to join a church planting team in Mikolow, where he is responsible for leading worship. Szczepan and Kamila have two sons, Noah and Aaron.
