About Tim

Host for Oak and Thorn on the first and third Sundays of every month, and The Ecology Hour on the fourth Tuesday of every month. Oak & Thorn aims to present the widest possible spectrum of Celtic music, from traditional to contemporary styles, along with information about history and culture. The Ecology Hour- Science Edition (co-hosted with Bob Spies) presents recent scientific findings about the natural world and our place in it. My other interests include brewing, gardening, birding, cooking, woodworking, and history. I live on Middle Ridge in Albion, California, among wonderful neighbors.
