Preston frequently speaks at various venues: churches, colleges, high schools, men's retreats, music festivals, women's retreats (just kidding), leadership conferences, and anywhere else where people want an authentic and vulnerable perspective on biblical and cultural issues. Preston loves to talk about the stuff that everyone is thinking about but no one wants to address.
Since Preston is a theological mutt, he's not limited to any one denomination or Christian subculture. He's spoken to Anglicans, Baptists, Presbyterians, Methodists, Lutherans, Charismatics, and that massive denomination that doesn't claim to be a denomination: the "non-denominational" folks.
If you cherish the gospel and love to sweep aside the Christianeze clutter to learn what the Bible really says about this and that, then you'll probably enjoy listening to Preston speak.
