Our Story

At Gillensport we eat, sleep, drink, and LIVE sports. The entire reason we started Gillensport was to get closer to the games we love. Some fans enjoy just watching the game, at Gillensport we take a hands on approach to sports fandom. Our entire team looks at sports memorabilia from a different lens. Everything in our vault has a story.

Our founder, Kiernan Gillen, has been obsessed with sports since before he could walk. Growing up in Orange County, New York, his love for baseball started with the Yankees. Whether it was catching a ball above the bullpen at Yankee Stadium or getting an entire Hudson Valley Renegades roster to sign a ball, the thrill of coming home with a souvenir was unforgettable. At Gillensport, we understand the joy in saving a ticket stub, holding it years later, and instantly remembering the plays that made it special.

Our roots are built on the belief that sports are bigger than the scoreboard. Gillensport exists to capture that magic — the feeling when a player takes a moment to sign a ball for a kid, the spark of excitement that turns into a lifelong memory. No matter your age, sports have a way of making you feel like a kid again. That nostalgia lives inside every piece of memorabilia, and it’s why we’re passionate about providing fans with the missing pieces to their collections.
