Gabriela COSTA

I’m a psychologist with extensive experience in human development and behavior. I believe Jiu Jitsu transforms lives by building confidence and resilience to face everyday challenges. At Essence, I hope to integrate the core values of Jiu Jitsu with psychology, serving as a facilitator for personal and emotional growth.

ASSISTANT COACH

 

Pilar Souder

“Training martial arts has been truly transformative for me. Physically, I’m stronger, more flexible, and equipped with the skills to protect myself in dangerous situations. Mentally, I feel sharper, more focused, and more confident than ever before. The BJJ community—especially the Essence community—is incredible. Training has pushed me to grow both physically and mentally, but even more importantly, it has given me lifelong friendships. BJJ is for life!”

CLARK DOMINGOS

As a teen, achieving goals is what I strive for — but what does that motivation mean if there are no goals? Jiu Jitsu brought a goal into my life: to improve. Being able to help provide goals for others makes me feel more complete.

“Jiu Jitsu has been one of the best, most life changing experiences for me. Not only has it helped me get in better physical condition but it’s also helped with problem solving and remaining calm in stressful situations both on and off the mat. One of the best things about working with kids is not only watching their jiu jitsu skills grow but also their confidence.”
