Stefan Mihailovic

Instructor & Kids Program Director

Stefan Mihailovic

Extremely passionate about jiu jitsu and very dedicated. Started off in 2019 with a competitive focus and a few gold medals as white belt and have gradually leaned more towards the theoretical and teaching side of the martial art. Spend hours studying footage and text, and digesting and integrating techniques from jiu Jitsu and other grappling arts. Have visited and trained at a few gyms around the USA including: Art of Jiu Jitsu, B-team and New Wave where I have learned from world class teachers and athletes such as: John Danaher, Gui Mendes, Tainan Dalpra, Gordon Ryan, Nicky Ryan and Craig Jones. My current goal is to develop my skills and knowledge in the martial art and also my teaching skills to eventually adopt Jiu Jitsu as a career. Im proud to say I’m the director of the 8-13 kids program where I am challenged every day to be a leader and a teacher to my students.

Assistant Instructor

Zachary Gilmore

My name is Zachary Gilmore and I am a jiu jitsu blue belt. For the past four years of my life, jiu jitsu has impacted me for the better. It has helped me become stronger and more confident in myself. Whether it’s because you want to become more athletic, defend yourself, or simply because you need a hobby; jiu jitsu will benefit your life just like it has mine. Not only has it brought me joy, it’s brought me immeasurable peace.


Florencia Colón

Office Manager & Assistant Instructor

Florencia Colón

Hey there, I'm Florencia, excited to be a part of Rincon Jiu Jitsu as the Office Manager and Assistant for the lively Future Legends class, dedicated to our young warriors aged 3-7. I began my Jiu Jitsu journey in 2021 and proudly wear a blue belt today.

Beyond the academy, I'm a certified yoga teacher, finding joy in how Jiu Jitsu and yoga complement each other. They might seem different, but they fit together like bread and butter.

Jiu Jitsu means a lot more to me than just a martial art. It's been a source of healing and strength, teaching me perseverance and discipline beyond the physical moves.


As the office manager, I'm your go-to person for anything you need. You'll often catch me with a laptop in hand or capturing moments for our social media in between sweaty rolls.
