“I am humbled and excited for this opportunity,” Griedl said. “We have accomplished so many things these last couple of years........ I want to keep that momentum going and go to the next level. Marshall has a great tradition and I expect all of our athletic programs, both boys and girls, to continue improving and moving forward to build on that tradition.”
