My wife, Jessica, and I got married in December of ’07 at Christ the Vine in Temecula (her home congregation). We then both graduated from Martin Luther College in New Ulm, MN in June of ’08. My first call was to teach grades 3-5 in Princeton, WI. My second year there I taught 6-8. The congregation decided to close the school so we received a call to serve in Peshtigo, WI and I taught 6-8 and served as Principal for 5 years. This past year I served as 2-4 grade teacher and principal at Beautiful Saviour in Carlsbad, CA.

Jessica has been a stay at home mom for the past 7 years. While she may stay at home, I am certain that she works harder than I do, not only does she raise our four children, Esther, Jacob, Naomi, and Levi , but she is greatly involved at every congregation that we have been a part of. This past year she helped out with Beautiful Saviour’s Mornings with Mommy program, started Monday Morning Coffee for the school parents, and also cleaned church.
