Emily Hughes – Head Coach


Emily began with gymnastics as a kid, and played basketball and soccer until high school, but spent most of her adult life enjoying much more sedentary activities–such as reading and writing (we know that surprises most of you). After finding herself in a desk job, and eventually growing bored and dissatisfied with said job, she was itching to do something active. She has always loved to travel and, being from Oregon, California was always one of her favorite places to visit. She found CrossFit here in Hollywood on one of those visits. To be honest, she was confused. Why were people spending all day in this place? Why was there a couch? Why were they acting like family? She decided to check out her local box when she got back to Oregon.  She started CrossFit with one single, simple personal goal–to do one pull up. She had no intention of mastering the sport, just merely surviving it. A few months later, she got that pull up…and the rest is history. She started spending all day at her box. People started joking that she might as well move in and sleep on the couch. And the members became her family. She obtained her Level I Cert up in Oregon, and competed in the 2013 North West Regionals on CrossFit Salem’s Regionals Team shortly after that.

“I truly believe if you aren’t passionate about what you do, you should start doing something else. So that’s what I did. I swapped my skirts and heels for Lulu and lifting shoes, emptied my purse and made my gym bag a permanent fixture wherever I went–which led me right back where my CrossFit journey began.”

“I coach CrossFit because I could only live the moment of my first pull up once, but I get to experience all kinds of accomplishments with my athletes every single day. I am just as elated to see someone complete their first painless air squat as I am to coach someone into their first successful muscle up. It’s not the technical difficulty of the skill that makes these milestones great, but that today you can do something that yesterday you could not. And who knows what you’ll be able to do tomorrow?!”

Brandon Sanborn


From a very young age until his freshman year of college, football was Brandon’s life. He had a very successful athletic career in high school where he was a three-time Alabama state champion: once with football, twice with track and field (shot put). He played one season of collegiate football at Murray State University (KY), then switched to rugby for one year at the University of Alabama, and then three more years at the University of Missouri. Though he lived for being out on the field, it was his devotion to training in the weight room that remained constant once his football and rugby careers came to an end. Brandon finally jumped into CrossFit in the Spring of 2012 when a friend referred him to Bruce. He became a SpeedX coach under Bruce and quickly transitioned from a stubborn bodybuilding personal trainer to fitter, stronger, faster CrossFit junkie. He drank the Kool-Aid, loved it, and now regularly competes in CrossFit competitions.  Along with coaching CrossFit, Brandon is also an experienced bass guitarist that has toured all over the country. You can also see him on occasion performing stand-up comedy. He’s so happy to be part of the Vault family!

Daimino Stewart


Daimino forged his way into CrossFit by way of football, basketball, and track and field.  Hailing from Marysville, Washington, Daimino was his high school football team’s quarterback/wideout and played professional football on the Arena and CFL Level.  He also took 7th place in the high jump in the state championships.  Besides being an avid athlete, Daimino dedicated his studies to anatomy and physiology in college. Through his hard work and perseverance, Daimino made it his goal to appear in the CrossFit Regionals and he accomplished it.  He is definitely someone to watch in the near future. “Sports and fitness have been a part of my life since I was 14 years old, I really don’t know anything else other than striving to become a better athlete everyday. Upon discovering how to eat to perform, I really studied what foods work for my body as well and how to integrate that with CrossFit.  Now my goal is to be the fittest man in the CrossFit world,  and my passion is helping others set goals and how to reach them!”

It took me an impressive 22 minutes to finish. I was hooked ever since”.

Tyler Emery is Vault’s USA Weightlifting Level 2 Coach and is heralding our olympic lifting classes.  Other certifications that Tyler holds besides his CrossFit Level 1 are CrossFit Movement and Mobility as well as attending the Optimum Performance Training (OPT) Exercise Selection Course.  Among his many accomplishments, he is most proud of his 3rd place finish in the 2010 California State Weightlifting Championships (94kg).  Tyler started doing CrossFit about six years ago and quickly fell in love with this approach to fitness.  It wasn’t long before I realized how much I enjoyed working with others to achieve their fitness goals. What stirs my passion for CrossFit is its ability to allow individuals to discover a side of themselves they otherwise might never have known. It is such a gift to be able to take the discipline and confidence that comes from mastering your physical being and apply it to the rest of your life.

Chanida Sintuu – owner/manager


Sport. What is sport? Webster’s defines sport as to deviate or vary abruptly from type. To deviate or vary abruptly from type.

Not everyone is born with the natural talent and athleticism of the aforementioned, but you don’t need that to walk into our CrossFit gym. You don’t need to be the best athlete in the world, your town or even your block. You don’t need super human strength, height or amazing coordination. You just need the nerve to come in for that first class and have a willingness to leave it on the floor to make a difference in your CrossFit community. Pushing through a wod when your whole body says no, when you’re completely drenched in sweat, when doing one more rep seems like the hardest thing in the world is what engenders people to one another and creates a community.  My goal and mission is simple: Create a community of people who are willing to deviate from type. CrossFit is accessible to anyone willing to work hard, respect one another, and strive to do something positive with their health and fitness. That’s Vault CrossFit. That’s the sport of fitness. That’s what every single person is capable of when they walk through those doors every day.
