Welcome to Hill Street Boxing

Hill Street Boxing was founded in 2018 in Southampton by East End locals Avery Crocker and Thomas Haynia with one goal in mind: to build a space where people of all ages and skill levels could train hard, build confidence, and feel like family.

In 2023, we expanded with a second location in Riverhead, led by coach and co-founder of that branch, Grant Keelan. Over the past year, Riverhead has grown into a thriving home for boxing on the North Fork—offering everything from youth classes to private training and sparring.

At both gyms, our focus is on form, fitness, and community. Whether you’re stepping in the ring for the first time or training for your next fight, Hill Street Boxing is where preparation meets purpose.

The first class during the week is free! Come see what we're all about.
