Welcome to Hill Street Boxing

Founded in 2018 in Southampton by East End locals Avery Crocker and Thomas Haynia, Hill Street Boxing was built to create a space where people of all ages and skill levels can train hard, build confidence, and feel like part of a community.

In 2023, we expanded to Riverhead, bringing that same energy to the North Fork. Today, both locations continue to grow as a home for boxing, fitness, and personal development—offering everything from youth classes to private training and sparring.

Your first class is free. Come experience why Hill Street Boxing is one of the fastest-growing gyms on Long Island.
