Randy Dunnett got his first experience in coaching baseball with Jack Perconte Sports back in 2000. At the time he was a player himself in between his two professional minor league baseball seasons. He served as a baseball instructor there for four years.
Then the Windy City Thunderbolts came calling, looking for a pitching coach. This was his old team and he couldn’t say no, so he took the chance and joined up. A year later Randy Dunnett founded the Finish Strong Indoor Sportsplex in suburban Chicago, and things have never been the same since then.
