"In 2017, I was asked by an organization to coach my first 8U travel ball team and coached with them for two years before coming to Thundercat Sports Academy. I love the game and the strategy behind it! I love teaching the “why” to players as to why we do things so they better understand the game and can think it for themselves. I have learned how to teach beginning pitching fundamentals and have my own hitting fundamentals I teach as well too."
