UPDATE: World Champion Danielle Gallo and her fiancé Aidan Oates have officially launched Underworld BJJ at 810 H St. NE in Washington, D.C., with a grand opening event scheduled for January 11, 2026. This new Brazilian Jiu Jitsu gym promises to transform the local community through family-friendly fitness and self-defense programs.
The grand opening is designed to engage both families and adults, showcasing a vibrant atmosphere filled with activities. The event kicks off with a ribbon-cutting ceremony for children and families from 11 AM to 12 PM, featuring games and sparring activities. Following that, from 12 PM onwards, adults can enjoy open sparring sessions and refreshments, ensuring everyone can experience the gym’s unique offerings.
Underworld BJJ aims to provide a welcoming environment for individuals of all ages and skill levels. The gym’s schedule includes beginner-friendly sessions, specialized classes for children and women, and advanced competition training programs available seven days a week. Gallo, a recent 2025 Purple Belt Jiu Jitsu World Champion, emphasizes the importance of using Jiu Jitsu as a catalyst for community building and personal empowerment.
The founders’ mission extends beyond traditional fitness, focusing on cultivating confidence and resilience among participants. Gallo shares that her journey through Jiu Jitsu has profoundly impacted her life, helping her overcome personal struggles and build a supportive network. She believes in the discipline’s ability to empower individuals to navigate life’s challenges.
In addition to fitness classes, Underworld BJJ will host various community events, including family movie nights, picnics, and Jiu Jitsu tournaments, fostering connection and engagement among residents. This approach is particularly significant given recent challenges in the D.C. area, including federal layoffs, as the gym seeks to be a hub for human connection and growth.
The grand opening event will provide an opportunity for the public to explore the gym’s offerings, meet the instructors, and witness the transformative power of Jiu Jitsu firsthand. Located conveniently at 810 H St. NE, Underworld BJJ stands as a vital addition to the neighborhood, committed to enhancing health, fitness, and community spirit.
As the grand opening approaches, Gallo and Oates invite everyone to join in celebrating this new chapter for both the gym and the community. This is more than just a gym; it’s a space for personal development, building relationships, and creating a supportive environment for all.
