Severson and his wife, Laura, have two sons – Jeff, a student at the Missouri University of Science and Technology in Rolla, and Eric, and Naval helicopter pilot currently deployed to Afghanistan. Mayor Penny Lyons and the Osage Beach Board will host a retirement reception for Dave Severson next Wednesday afternoon.
