Meet Jackson Greer

Jackson Greer founded JG Training Academy in 2022 to ignite passion, instill discipline, and build confident athletes prepared to compete at the highest levels of the game.

Jackson’s journey is defined by resilience and work ethic. Unranked out of high school and holding just one Division I offer, he was never the most naturally gifted player on the field, but he was always willing to outwork everyone else. His college career began at East Tennessee State University, where he hit .125 as a freshman and faced real uncertainty about his future in baseball. Instead of backing away, Jackson committed to the process of daily improvement and long-term development.

That commitment paid off. He developed into a 1st Team All-SoCon catcher, earned placement on the Buster Posey Award watch list recognizing the nation’s top catchers, and competed as a Cape Cod League All-Star. He later transferred to the University of Tennessee, achieving a lifelong goal by playing for his hometown team and competing in the 2021 College World Series.

Today, Jackson brings that same standard of excellence to every athlete at JG Training Academy. His mission is to make the development process clearer and more efficient for players and families by teaching proven fundamentals, disciplined habits, and the mindset required to advance in the game. Whether an athlete’s goal is to compete at the next level or pursue a future in professional baseball, Jackson understands the expectations, the workload, and the commitment required, and he is dedicated to helping athletes reach their highest potential.

  • "Jackson Greer was the type of player that embodies Vol Baseball. He brought an SEC level of skill to the field everyday. More importantly, he brought with him a high level of character. Work ethic, selflessness, energy and intensity are attributes that are brought up all the time in athletics but not everyone can meet a championship standard in those categories. Jackson does. He already has accumulated a large amount of time contributing to the community, but now that his time is complete as a player I look forward to seeing how many lives he can impact by relaying and teaching the formula that made him a successful player and teammate."

    — Tony Vitello, University of Tennessee Head Coach 

    "Jackson's personal development as a player speaks for itself, but what really sets him apart is his ability to communicate simply with others. He is a true self-made player with an incredible work ethic that I would trust to work with any of my D1 or Pro guys. "

    — Caleb Longley, University Of Texas Hitting Coach

    "Anyone that has the intentions of pushing themselves to an elite status look no further. Jackson has an incredible background and is a well of knowledge stemming from his time as a player at the highest collegiate level. If you're serious about development at the catching position then take advantage of the opportunity to work with Jackson Greer.

    - Skyler Barnett, Milligan University Head Coach

    "Jackson has performed at the Division 1 level with success. He is passionate about catching and there is no doubt he will take that passion along with his experience to develop catchers in the area."

    — Tom Griffin Head Baseball Coach Carson Newman University

    "Jackson Greer, for as long as I can remember, has always been the hardest worker on the field. His knowledge when it comes to hitting and catching is right at the top with the best. Anyone looking to become an elite catcher or hitter would be missing out if they didn't have a chance to hear what all he has to offer. Hands down one of the best players I've ever played with."

    — Alex Haynes, Colorado Rockies
