Leadership – Pablo Staniszewski

Pablo Staniszewski’s passion for customer service drives everything he does at DOT40 LLC. His love for firearms started early in Argentina, where he trained in traditional shooting disciplines. But it wasn’t until he saw his first IPSC competition that he truly found his passion.

Since then, Pablo has dedicated himself to training hard, competing at top levels around the world, and connecting with others who share his enthusiasm. Reloading is also a big part of his process, it fuels both his performance and his love for the sport.

Today, Pablo is proud to be part of the 2025 Mark 7 Shooting Team, and he brings that same dedication and passion to delivering great service for every customer.
