While Dave has coached other sports at Keystone, his tenure as a softball coach will long be remembered.  His softball coaching career began in 1978 assisting his wife Suzanne who was Keystone's first fastpitch softball coach.  Dave later took over as the head softball coach in 1980 and held the position for 20 years, retiring this year.  Over this period, Coach Leffew led his teams to an overall record of 424 wins and 77 losses or a winning percentage of 84.6%.  The team claimed 13 conference titles, 1 in the Inland and 12 in the Lorain County Conference.  For all 20 years, Dave's teams won the Sectional Championship.  Thirteen Teams went on to win District Championships and 6 of those teams won Regional Championships.  His teams 6 Final Four Appearances were in 1992, 1994, 1996, 1997, 1998 and 1999.  They were the State Division II Champion in 1999.

The accomplishments of Coach Leffew's teams have not gone unnoticed by his peers.  He was named Coach of the Year in the conference 12 times, Lorain County Coach of the Year 9 times and twice selected the Northeast District Coach of the year.  He was given the Sportsmanship Award, as voted on by local umpires, on two occasions.  He was elected President of the Lorain County Coaches Association 5 times and the Northeast District 3 times.  This induction is not Dave's first exposure to a Hall of Fame.  In 1998, he was inducted into the Ohio Fastpitch Coaches Hall of Fame.

Dave Leffew is the first and only coach in the history of LaGrange Keystone schools to lead a team to an appearance at a State Championship Tournament, earn a State Runner-up and win a State Championship.
