Delhi’s Knapp Becomes First Female Brazilian Jiu-Jitsu Black Belt in Delaware County

DELHI — In a milestone for martial arts in the Catskills, Heather Knapp was promoted to black belt in Brazilian Jiu-Jitsu on March 15, becoming the first woman in Delaware County history to achieve the rank.

The promotion, which took place during Women’s History Month, places Knapp among a small group of women in the rural region to reach the level. She received the honor from Marcio Bittencourt, a practitioner renowned in the combat sports community for maintaining rigorous competitive standards and a prestigious lineage.

Brazilian Jiu-Jitsu is often cited as one of the most demanding disciplines in martial arts, typically requiring a decade or more of consistent training to achieve a black belt. For Knapp, a coach at Mushin Martial Arts in Delhi, the achievement follows years of balancing her career and family life with the physical demands of the sport.

"This isn’t just my black belt," Knapp said. "It’s for every woman who ever felt like they didn’t belong in spaces like this. We do."

The accomplishment is being hailed by local practitioners as a breakthrough for representation in a sport that has historically been male-dominated. Beyond her personal rank, Knapp’s role as a coach has made her a focal point for self-defense and empowerment programs in the area.

Ben Dixon, head coach at Mushin Martial Arts, noted that the promotion carries extra weight because of the lineage involved.

"What Heather has done isn’t normal — it’s historic," Dixon said. "And to earn that recognition under someone as respected as Marcio Bittencourt makes it even more meaningful."

As the sport grows in Upstate New York, Knapp’s promotion is expected to influence the next generation of athletes at the gym, particularly young girls and women seeking a path into combat sports.

"Her presence is helping reshape what martial arts looks like in rural New York," the gym stated, noting that Knapp's journey serves as a signal that traditional barriers in the sport are continuing to erode.
