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.
