Welcome to the Rogue Family

Jonathan Grossman

Co-Owner, Brazilian Jiu-Jitsu Purple Belt, Head Jiu-Jitsu Coach

Jonathan began training in Brazilian jiu-jitsu at the age of 32, eight years ago, after years of interest in BJJ. He was 280 pounds with no athletic background and no idea how his first class would go, he always thought, things like BJJ were for “those type of people” and not for him.

After mustering up the confidence to attend his first class he realized he had found the thing he should have been doing for years. He started to notice that the lessons he’d learn in jiu-jitsu applied to other aspects of his life … hard work, goal setting, focus, mindset, all things that helped his success in jiu-jitsu also helped with success at work and in day to day life. After a short bit of time training he began to realize that he enjoyed helping others learn and decided teaching would be the main focus of his jiu-jitsu future.

Jonathan has traveled all over the country training and competing, and looks forward to continuing training, teaching, and growing with his Rogue Academy family!

An Air Force and war in Afghanistan vet, he is also currently an IT contractor.

He is a decorated war veteran with multiple combat deployments serving as a leader of high performing teams.

Leveraging recreational activity, the association provides family advocacy, grief bereavement and self-care to assist families before, during, or after a mental health crisis and to reduce the stigma of mental illness.

Keileen Estrada

Yoga Instructor

Keileen Estrada graduated with her Bachelors of Science in Exercise and Sport Science with a minor in Psychology. She became a certified 200 YTT in October 2020 but began instructing in 2018 during her course work with the help of mentorship and advocacy of one of her professors that lead her down the path of Yoga.

Keileen is certified to teach Hatha Yoga, Yin Yoga, Vinyasa Yoga, and Kin Yoga at all levels and has incorporated music/sounds to allow her class to feel the vibrations with each breath they take. She has a strong passion for teaching others to have a better connection with their body, mind, and soul. Through her practice she allows everyone to feel welcomed and comfortable where they are able to come as they are and feel at home. Being in an environment that is accepting, and open minded allows for individuals to better express themselves whole heartedly and give them the opportunity to challenge themselves in ways they would have never imagined.

Like many, she views yoga as a holistic approach, which heals the body by making everyone feel whole and aligned. Every aspect of Yoga plays a key role in the healing process through body movement, meditation, breathing exercise or relaxation. Yoga stimulates mental, physical and spiritual health to flourish and her main goal is to provide it in all forms through her sessions while allowing everyone to feel motivated and in control of their own journey through affirmations, and instruction.
