ATOS Reno Brazilian Jiu-Jitsu


Atos Jiu-Jitsu was originally founded in 2008 and has grown to become one of the most recognized and respected names in the world of Brazilian Jiu-Jitsu.
Since Atos was first established, they have grown into a powerhouse team, with 70+ affiliate academies around the globe. Atos Reno Brazilian Jiu-Jitsu was the first of those affiliates, originally operated by Kelley Perotti, 3rd degree Black Belt and 2x Masters World Champion. In November 2023, Arturo Espinoza took over ownership of Atos Reno Brazilian Jiu-Jitsu, and it was a fitting transition. Arturo was Kelley’s longtime family friend and the first student to earn his black belt under her mentorship and received his black belt in 2016 from Processor Andre Galvao. A veteran with 11 years of teaching experience and multiple championships, Arturo is excited to share his passion for BJJ and continue the legacy of both Atos and Kelley.

Owner & Head Instructor

Professor Espinoza

Training Martial Arts

Always had an interest in Martial Arts since I was a kid. Main focus growing up was boxing, but my first exposure to MMA and grappling was during my time in the military. I fell in love with it and decided it was something I wanted to continue training and soon became an outlet for everyday stressors.

Teaching others in Martial Arts

I want them to benefit from it the way that I have. I truly feel that Brazilian Jiu-Jitsu has made me a better person all around, even off the mats. I want to share my passion with anyone who is willing to learn especially those that are stepping out of their comfort zone. It can be intimidating and there can be some self doubt at the beginning but then they can discover something about themselves that they already possessed. With guidance and support anyone can learn Brazilian Jiu-Jitsu, as long as they have an open mind and commit.

How long I have been teaching

I have been teaching Brazilian Jiu-Jitsu for about 11 years.

My passion for teaching BJJ

I feel that I am passionate about teaching Brazilian Jiu-Jitsu because I consider myself a never ending student of the art. I have gained so much on and off the mats from training and I want to be able to share that with my students and want them to experience the same if not more.

Who Inspires me

I have been truly inspired by my family. My wife has always encouraged and supported me even during times that I struggled with balancing work, family, and life. My children who have also been competitive in sports and have shown perseverance and heart throughout their struggles within their sports. They have given me the motivation to do and be better. And my parents, especially my late mother. She instilled strength, confidence, and courage from a young age. Always encouraging me to follow my heart and dreams.
