Impact Dynamic Training

Impact Dynamic Training was founded in 2010 by Rey Castillo upon the belief that through positive reinforcement, a player can achieve their best.

Impact Dynamic Training aspires to be an outstanding educational, athletic training organization, which provides a high-quality experience to every athlete.  We strive to make each athlete an important part of the team, and help them achieve their highest potential.  We recognize that the coach is an important asset in fulfilling this obligation.

It is our goal to provide our coaching staff with the necessary tools to successfully impact each athlete.

Impact Dynamic Training is committed to creating an encouraging culture, embracing diversity, and adhering to the principles of fair play and sportsmanship.  In partnership with the coaches, parents, and athletes we will work together to achieve our goal.


Our Mission is Simple.  To provide professional, deliberate teaching and coaching to each individual player while enhancing the skills of their game and to build their confidence in the process.


Impact's dedication to quality is so notable that in 2015 Impact was awarded a Best of Grandville award.



“We just wanted to send you a quick note to say thank you for the role that Impact has had in Nicole's development.  She has been asked as a freshman to move up to play with the JV team this fall and is super excited.  She went from getting cut as an 8th grader (following her surgery) to getting pulled up a level the following year.  While we give her a lot of credit for the hard work and dedication she has shown the last year, it would not have happened without the coaching and opportunities she has had through Impact.  It's been a great learning experience of what you can accomplish when you put your mind to it” ML

"Every youth sports organization has its positives and negatives. However, Impact Dynamics and Rey Castillo Jr. go over the top to live up to their word. It's not about winning every match or weekend - it's the journey to become better people, players, and teammates." SB

"Ally and I just want to thank you for an amazing season at IMPACT.  This season was not easy for Ally, but it taught her a lot of important things - both with VB skills and working as a team.  This was more than just volleyball skills for sure. Ally's VB skills just went through the roof in these few short months.  She was not confident in herself or her abilities at the beginning of the season, but was playing so well at the end.  I appreciate what you did to help her and she' much more prepared for the upcoming freshman year.  I just want you to know how much we appreciate IMPACT and your attention to Ally in this past season.  I know she was not your best player, but you never made her feel less important than any of the other plays and I appreciate that.  Wishing you much success in the future!"
