Joel is the GM of Keystone Fieldhouse and has over 20 years of coaching/instructing experience for different levels. He has an absolute passion for coaching, instructing and helping youth of all ages in any way possible. A long time resident of the area, injuries forced him to hang up his glove, so he turned his baseball journey to coaching and makes top priority of safety and the well being of players. He recognizes that every player is different and must be coached as an individual.  What works for one may not work for another and what one understands, another may not.  Joel believes strongly in setting short term goals for long term success and looks at a players baseball journey as a marathon not a sprint while stressing to them enjoying the ride, staying hungry and staying humble.  He teaches players to not fear failures but instead get out of their comfort zone and learn from and become better because of them and emphasizes not only measuring their success on the field but off the field as well.

Speed, Agility, Strength Development

Nick is available for group, team or 1 on 1 training. If you have questions or want to discuss scheduling please text/call him at 717-658-2557 or email

Nick Graham played baseball at Chambersburg Senior High School as varsity catcher from 2010-2014 and went on to play two seasons at Penn State University 2014-2016 as a catcher.  He played shortstop and catcher for one season at University of South Carolina Beaufort, then finished his career at Millersville University playing one season as a catcher, second baseman, and left fielder.

Nick studied kinesiology/exercise science in college and graduated from Millersville with a Bachelor of Arts in Biology and Wellness of Sport with a focus on coaching.   Throughout his academic career he focused on bio-mechanics and using that knowledge to better his playing career. The processes and theories he developed from the combination of human science academics and his personal baseball career will be used to teach young athletes how to move correctly.

The theories that he will teach are focused around efficient movement to produce low stress, high-energy movements so that the athletes stay safe as they become bigger stronger and faster.

The lessons learned through baseball and academics allowed Nick to take inconsistent results in his first two seasons into hitting over .300 with increased power numbers in his last two seasons.  The theory Nick used for himself is based on bio-mechanical principles that contribute to all aspects of the game. These theories also allowed him to recover from labrum surgery in high school to come back and throw harder with less stress allowing him to continue his playing career.
