Greg,
I wanted to give a thanks and a huge plug to your academy from last winter for Justin. Last winter due to wrestling, Justin just participated in the hitting sessions at your academy in Jefferson. I knew he spent a lot of time on the fundamentals and with Aaron in particular. The results were outstanding from my viewpoint. He hit the ball better than I ever saw him before. Thanks again for your help.

“Last year my son, who is no stranger to pitching camps, attended the baseball academy for pitchers in Watertown. For the first time in several years he was truly excited to go to the sessions and even informed me that he had learned some things that he had never been exposed to in other camps. Greg has the attributes that make the academy a true learning experience: he is knowledgeable, his helpers are knowledgeable, and they relate well to the young men they are instructing. If you are only able to make one pitching academy this year, the Greg Reinhard Baseball Academy should be at the top of your list.”
-Marvin

"Greg Reinhard and Aaron Guilbault are two of the most fundamentally sound baseball coaches I’ve been associated with. Their biographical histories are second to none. Furthermore and most importantly, their human character skills and values which they model for the athletes in the academy would encourage any father to entrust the future baseball and character skills of their sons to them. My son learned so much about hitting because of the high percentage of one on one coaching.”
-Steve

“Greg Reinhard was one of the most respected teammates I’ve ever played with. His competitiveness and knowledge of the game made him a joy to play with. When I think of someone with the skills to teach baseball and to make people better I think of Greg."
-Sam Fuld, Chicago Cubs

“Greg represents all that is good about baseball. He was always an incredibly dedicated client and I have no doubt that he will bring that same intensity to his baseball academy. His desire to succeed and to share his expertise will be what sets him apart from other baseball academies.”
-Matt Sosnick, Agent & Owner of Sosnick Cobbe Sports
