  • Director

Lars Bo Olesen

Lars has been the director of Acts Academy since August 2020, guiding the school through an exciting season of transformation. He also serves as lead pastor of Open Church Herning and as the global leader of a growing network of churches that share the same name and heart. Since its founding in 2008, Open Church has been driven by a passion to be a church for those who do not yet attend and to make the supernatural natural. The church is not meant to be an isolated island but a storehouse for people, where faith, community, and action go hand in hand. Prophecy is not merely a church activity; it is a lifestyle that helps spread hope and the Kingdom of God throughout every part of society.
