TESTIMONIALS

" The work that Trevor Tierney is doing to help goalies is truly transformative. My son has never had personalized goalie instruction and is thriving under his guidance. Trevor is humble, patient, and positive.

He looks at each goalie, sees their potential and works to build them up so they see it as well. His two-step approach of working both on and off the field with his goalies is what sets his program apart.

He cares just as much about the goalie off the field. In this age of crazy competitive sports, it is incredibly refreshing to work with Trevor and his unique approach to athletes. These kids are so much more than their sport and Trevor realizes that and sets these kids on a really great path toward

accomplishing all of their goals. "

" One play development is an outstanding option for athletes just like me who need help with their mental performance. One Play Development, particularly focuses on mental performance, can be a game-changer for athletes. It’s not just about physical skills, but about building that mental toughness, focus, and confidence to perform under pressure. Techniques like visualization, mindfulness, mental rehearsal, and self-talk are often used to help athletes sharpen their mindset, reduce anxiety, and boost overall performance. "

" Working with Coach Pat Tracy has been a huge part of my growth as a lacrosse player. He takes the time to break down my game film with me, identify what I need to improve, and then designs specific drills to turn those weaknesses into strengths. Beyond the physical work, he's helped me understand the game at a higher level and stay confident and composed in high-pressure situations. Every session has a clear purpose, and I always leave feeling more prepared, more confident, and better equipped to compete at a high level. "​

" Coach Casey O'Neill and One Play Development truly represent the gold standard in lacrosse training. Their commitment to each athlete goes far beyond basic instruction—they invest in developing the complete player, both on and off the field. With expert knowledge, unmatched energy, and genuine care for every student’s growth, they consistently push athletes to reach their highest potential. The individualized attention and relentless dedication set them apart from any program we’ve experienced. If you’re looking for the best of the best in lacrosse development, One Play Development is it. "

" One year ago, my left hand was very raw, I struggled to shoot on the run, and I wasn’t nearly as explosive as a player. Through one-on-one sessions and small-group trainings with Coach Stimmel, he pushed all of us to improve by competing against some of the best players in Western PA and helping me become a more complete player. 

I went from being a player who never focused on the mental side of the game—someone who would slam their stick, hang their head, and get frustrated over one play—to a player who can make a mistake and move on to the next play immediately.

​

He’s helped me in so many ways, improving my game not just physically, but mentally as well. My left hand, which once felt uncomfortable, is now something I’m confident using on the run—sometimes even more than my right. Overall, he truly transformed me into the player I am today, and without his coaching, I wouldn’t be in the position I’m in now. "

My son is currently a sophomore in high school and has been working with One Play Development for about a year now. Coach Woodson and the One Play team have provided far more than just lacrosse instruction.  They've been true mentors—not only helping my son grow as a player, but also guiding him in how to manage academics and the demanding schedule that comes with being a serious high school athlete.

​

What really makes One Play stand out is their emphasis on personal development just as much as athletic development.

A lot of their work happens "between the ears."

My son spends as much time talking through his goals in the classroom and life off the field as he does breaking down the X's and O's of lacrosse. That balance has been incredibly valuable.

The mentorship feels less like a traditional coach-player relationship and more like a trusted adult genuinely invested in his growth as a person.

Another thing I've really appreciated is how collaborative the One Play coaches are. They work together as a team, sharing insight and perspective so the athlete benefits from multiple experienced voices rather than a single viewpoint.

​

Every coach on staff is clearly well-established-having played and succeeded at the highest levels—and that experience shows in both how they teach the game and how they guide young athletes through the process. Over the last seven months, l've seen clear progress-not just in his play, but in his confidence, focus, and long-term mindset. 

One Play understands that success on the lacrosse field is driven as much by mental preparation and discipline as it is by athletic ability. As a parent who cares deeply about my son's development and future, I truly believe One Play knows how to help young athletes build the mindset needed to

navigate the path to the next level, both in sports and in life. "
