In 2006, he moved to Vienna, Austria where he first pastored the Baptistengemeinde Hütteldorf for three years and then taught at the Evangelikale Akademie / Campus Danubia for nine years. In 2019, he helped plant and now serves as the Lead Pastor of Christus Gemeinde Wien, a German speaking Reformed Free Church in the heart of Vienna.
