Mary Jo became the first women's varsity athletic coach to be inducted into the Hall of Fame. A 1964 graduate of The University of Akron, Chionchio returned to her high school alma mater, St. Vincent, where she remained for 17 years. She was head coach of three sports - basketball, track and volleyball. In track her teams won 40 of 46 meets from 1966-71 and her volleyball squads captured 93 of 100 matches from 1971-78. However, it is in basketball where Chionchio achieved her greatest success. In 17 years on the job, her Irish girls had 10 undefeated seasons and her record was a phenomenal 234 wins and only 22 losses. From 1969-75 her St. Vincent teams strung together a 72-game win streak - a state record. Mary Jo also guided the Irish girls to back-to-back Ohio AAA titles in 1978-80, including an unbeaten mark of 26-0 in 1979-80.
