A gym fit for a hero

Coach Justin grew up in the world of competitive gymnastics from age 6-13 under the tutelage of Edward Azarian and Xiaoping Li, two former Olympic Medalists and World Champions. After gymnastics, Justin entered into the world of Competitive Cheer and competed for the PACE All-Stars for 3 years; His varsity team won two consecutive National Championships. During this time Justin earned the prestigious Eagle Scout Award after 13 years in Cub and Boy Scouts. After he finished Competitive Cheer, he spent high school and college competing in Spring Board High Diving, culminating in a first place finish at the 2007 California State Championships. That same year, Justin finished up his Aggressive Inline skating career with an 8th place finish at the AIL Skating World Championships in the non-sponsored category. After finishing his degree in Industrial Technology from CSU Los Angeles School of Engineering and Technology, Justin began training in parkour and freerunning as well as performing in trampoline, gymnastics, and stunt shows. Justin has always loved teaching children, which stems from his mother running a day care out of his house while he was growing up. After years of gymnastics training and a lifetime surrounded by children, Justin earned his first coaching position at the young age of 13 and has been coaching in gyms and on pool decks ever since. After 13 years of coaching, Justin grew dissatisfied with the restraints placed upon his teaching in mega sized gymnastics gyms. This led to his goal to open his own training academy that offers classes in any and all types of movement.



Coach Glenn’s favorite part of coaching is showing kids there are more options than just the traditional path. He began his parkour career at the age of 14 and his love for Avatar: The Last Airbender and Assassin’s Creed encouraged this passion. Parkour made him an athlete and gave him the ability to become a trainer and mentor. While one of his favorite places to practice parkour is outside, Coach Glenn knows the safest place to train is inside a gym. He lives by the philosophy, “Until you try to teach someone else the move, you don’t really know it yourself.” He also recommends that kids try team sports since they encourage an understanding of how to work with people for a common goal.



Angel Griffin has had a passion for long term health and fitness from the age of 12. She studied team gymnastics at 8 years old, competed in her teens in rock climbing, and made it to the top 300 in the U.S. for Cross Country running at age 16. In college, she studied Sports Massage Therapy, Nutrition, and earned her B.A. in Japanese. While at the same time went on to win National Championships in Lindy Hop Swing Dancing and Salsa, studying the historical art under the tutelage of Minn Vo, and was hired to perform on shows like American Idol. She currently holds a black belt in karate and runs Firestorm Talent & Entertainment, Firestorm’s talent program that allows young athletes to become professional performers and book them professional acrobatic work.



Nathan's job is to make all of us weirdos at Firestorm look really, really cool. In high school, he presented the idea to his principal of including parkour as a PE class. Ultimately this suggestion was turned down and Nathan pursued his media craft. Fast forward 6 years of  countless days of freelance work, Nathan found Firestorm and his passion was re-awoken. After sending us a cold email he began creating the Firestorm window banners and the rest is history. Nathan now runs Firestorm's social media, updates the website, films and edits all the videos, and creates all the posters and graphic designs. No, we aren't sure if he is human!



Coach Flores started his athletic career before his first day of grade school. Before starting his Parkour/Freerunning training he had a successful career in team sports, which he continued into college. After graduating high school he found Firestorm Freerunning and Acrobatics, where his natural speed helped him progress at a rapid pace. Starting as a student, then volunteer, eventually Coach, and now the gym’s Manager, Coach Flores has always loved Firestorm and it’s community. After graduating from California State University, Fullerton he started working at Firestorm full time and has become one of it’s most integral pieces. He firmly believes that “The greatest pleasure in life is doing what people say you cannot do.” and is always proud when his students advance past what they thought was possible.

take both my boys here. They love it. The coaches are amazing!!! They are real into safety and make sure all the kids get plenty of water. My oldest has asthma and his coach makes sure he’s good at all times!

My son had the most fun birthday party here. And I had a great time in one of the Ninja Warrior classes learning how freakishly hard all those obstacles are that I’ve seen on TV. The staff are friendly but firm with the kids, ensuring that they enjoy themselves while staying safe. And they are very encouraging.

I brought my almost 5 year old son to parkour class today and he loved it. Coach Gabe is great with the kids and continued to correct their form and tell them they were doing a great job. I love that he would push them to try harder. We are now members.

I’ve been here for half a year now. It’s like an adult Chuck E Cheese. If you want to train like the superheros and move like Assassin’s Creed and do cool flips and s**** then I would come train here.

This is a passionate group of people. I didn’t get a sense of “ego” in this environment, but make no mistake, these are talented people. The feeling of personal growth is strong here. Everyone from parents dropping off their kids to Cirque du Soleil performers can be found here.
