Introduction SD Sports Agency
Train for life, not just for the game
In today’s sports world, mental coaching and personal branding are inseparable. As the owner of SD Sports Agency, I believe that athletes-and other high performers-can only truly excel when they are both mentally strong and able to express a powerful, authentic personal brand.
Mental coaching is about strengthening your mental resilience, self-awareness, motivation, and ability to handle pressure. It not only helps you perform better, but also enables you to be authentic and consistent as a person-both on and off the field. Personal branding is about consciously building your unique identity: knowing what you stand for, sharing your story, and being visible as an athlete, entrepreneur, or leader.
It’s precisely the combination of these two that creates a positive synergy. A high performer who is mentally strong communicates their brand with credibility. Conversely, a strong, authentic brand boosts your confidence and motivation. This way, you build not only sporting or business success, but also sustainable impact and value for the future.

Dennis Vallen Founder of SD Sports Agency
About me
Every high performer knows it: the drive to grow, the search for balance. My own journey began with an unexpected setback-one that left its mark on my body but made my mind stronger. Sport became my arena for personal growth and visibility; it taught me that real strength lies in embracing challenges and building your own story.
At SD Sports Agency, I help high performers not only become mentally stronger, but also make their personal brand shine. In a world where talent alone isn’t enough, a powerful personal brand makes all the difference-on the field, in the boardroom, and beyond.
My experience in sports, business, and leadership has taught me: those who dare to share their story create lasting impact. Ready to take your performance and personal brand to the next level? Get in touch, and let’s make your unique strengths visible together.

About me
At SD Sports Agency, I live and breathe sport. The agency I represent is built on passion, dedication, and a drive for excellence-just like the athletes and high performers I work with every day. My lifelong commitment to football, now as a goalkeeper for VVV-Venlo, has taught me the importance of mental strength, resilience, and setting clear priorities. Alongside my sports career, I’ve developed expertise in sports marketing, learning how to combine athletic insight with branding strategies that create real, lasting impact.
Whether it’s on the field or in the boardroom, I believe true success comes from a blend of focus, authenticity, and the courage to share your story. At SD Sports Agency, I’m dedicated to helping others unlock their potential, achieve their goals, and build a brand that stands out-today and for the future.
