My work has been published by the Sports Illustrated (when it was still the end-all-be-all of sports photography), ESPN, the Atlantic, the Player's Tribune, the New York Times, the Boston Globe, Sports Business Journal among others.
At the beginning of my career, I would set alerts for my published images as "tear sheets" with the proliferation of "subscription" services, my images are now ALL over the internet and I no longer actively watch or maintain record of where my images are published.
