Mabry fell in love with the development side of coaching and mentoring athletes along their journey. "It was at The Grind where I was able to clock in hundreds of hours of guiding players through improving their skills. My time there was an incredible accelerator in my own development both in teaching the technical side of the skill building but also in my communication skills in 1 on 1 or small group settings".
In the fall of 2016, Coach Mabry was hired as an assistant coach at St. Paul VI Catholic High School. He assisted in all phases of the game and was in charge of the teams off season development.

"Being on the staff at St. Paul VI Catholic has given me the opportunity to coach high school lacrosse at the highest level. It continues to provide me with intense competition to sharpen my coaching skills. As well, it gives me great insight to what it takes for players to reach their potential on and off the field. I absolutely cherish the program and community that we continue to build."
From 2018 to 2020, Mabry served as Director of Coaches and Players Development for the Hammers Lacrosse Club in Leesburg, Virginia.

"While with the Hammers Lacrosse Club I was able to help build a culture based around work ethic and positive momentum. Coaching players of all ages and skill levels helped me understand proper progressions as well and how to make the learning environment fun and fast paced. I am so grateful for all the time I was able to spend on the field with the players and families of the Hammers Lacrosse Club".
In the summer of 2019, The Ryan Bartel Foundation provided the opportunity for Coach Mabry to get certified as a Sources of Strength Trainer.

Coach is actively volunteering with the Ryan Bartel Foundation by training teenagers and adults in the Sources of Strength program. "Being able to work with so many young people through the Sources of Strength trainings has been an extremely rewarding experience. It has helped equipped me with the tools to continue to build resilience in my own life as well as the tools to guide others towards strong mental health. Continuing to help young people with their mental wellness and building cultures around that is still a major focus of my career."
Currently, Coach Mabry is dedicated to helping athletes achieve their potential both on and off the field through his various programs. "I am so grateful to be working with so many great student athletes in the Northern Virginia area. My main focus is to empower others with knowledge so that they can take the reins in their development wether that be focused on lacrosse skills & IQ, nutrition or mindset. I am excited for all of the future players that I will get to work with and the progress they will make!"
