He spent 27 years as a reporter and editor at The San Diego Union-Tribune after stints at The Houston Post and at two papers in his native Michigan. A features/human-interest writer in the UT's Currents section for many years, Mark also spent about a third of his UT career as an editor and reporter on the Metro Desk. He has covered a wide range of events: Wild fires in Southern California and Hurricane Katrina on the Gulf Coast; Super Bowls and the World Series; foster care and child-abuse issues; the Roman Catholic Diocese's sexual-abuse scandal and bankruptcy; royal visits of Queen Elizabeth, Prince Charles and Princess Diana; Republican and Democratic national conventions; high-profile criminal trials; and many other stories, from the silly to the sublime. Along the way, he interviewed everyone from presidents to pan-handlers. His work exposing the false accusations and prosecutions of several San Diegans for murder, rape and child abuse garnered Pulitzer Prize nominations and many regional and local journalism awards, including Best in the West, the Sol Price Award for Responsible Journalism and several San Diego and California bar-association awards. Mark has a degree in journalism from Michigan State University.
