He is married to his wife, Tracy, and has two grown children who both live in Iowa City. He was thrilled when he recently became a Grandpa for the first time to his granddaughter, Charlotte. Mark grew up in a neighboring town, Grafton, Iowa, so he was already very familiar with Osage when he came to work at the firm which is currently known as Walk & Murphy in 1992. In addition to his work at the firm, Mark also owns and operates Watts Theatre in Osage. Between his work at both places, he keeps busy. He enjoys visiting his girls, his son-in-law, and granddaughter in Iowa City; attending University of Iowa sporting events, taking fishing trips, and mushroom hunting. In addition to his private practice at Walk & Murphy, Mark is also the County Attorney for Mitchell County.
