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 developmentโ€”offering everything from youth classes to private training and sparring.
