Ten-time Arizona All-American swimmer Marcus Titus, a former member of the U.S. national swimming team, 2009-12, is making a comeback for the 2016 Rio de Janeiro Olympics. The Flowing Wells High School grad left swimming after finishing eighth in the 100 breast stroke at the USA Olympic Trials in June 2012 in Omaha, Neb. At 27, Titus has resumed swimming with the Ford Aquatics program and is about to launch a fund-raising program to cover his training program. He is one of the most successful deaf swimmers in history.
