Amy Dockus

Operations Director

Growing up moving every couple of years, Amy discovered that playing sports was a good way to fit into her constantly changing environment. She was a strong soccer player from an early age, often playing on boys’ teams because the opportunities for girls were limited. She was an All Conference and All State player in high school and was recruited to play Division 1 soccer for Villanova University, where she graduated with a Bachelor of Arts degree, double majoring in English and Communications. Four knee surgeries took Amy off of the competitive soccer field, but she continues to play a diversity of sports and stays fit by participating in CrossFit classes and running. She is also an adrenaline junky and has felt the thrill of solo accelerated free-fall skydiving, bungee jumping off a 500-foot railroad bridge, class 5+ whitewater rafting, running the New York City marathon, and circumnavigating the country on her motorcycle more than once. True to her gypsy roots, she’s lived the softer side of San Francisco and the harder side of New York City, and she has backpacked through thirty different countries within South America, Central America, Mexico, Africa, Asia, and Europe. Prior to becoming Operations Director at The Cave, Amy served as Office Manager where she helped create the administrative infrastructure that is in place today. She previously worked in a variety of service and management positions, including being a Product Development Manager for Restoration Hardware. She also spent a year in Africa working for eight different non-profit organizations in twelve countries. She worked in orphanages, counseled street children in the Kampala slums, taught kindergarten and art classes, coached a traveling girls’ soccer team in the Kibera slums, helped build and paint schools, took photographs for fundraising and social media back in the United States, and created a large-scale art mural with child soldiers in a village in Northern Uganda. Her outreach and working with children were clear indications that she was a good fit for The Cave. Amy stays involved in the community by volunteering with the American Red Cross as a First Responder for national disasters and on the Northern California Disaster Action Team. She loves all things creative, spending one of nine years at Burning Man building a 20-foot art sculpture with acceptance from the Black Rock Arts Commission. Business has more than tripled since Amy joined The Cave in 2012. She can’t wait to see what’s next on her journey.

Shawn Kelley

Facilities Director, Coach

Meet our dedicated Facilities Manager, Shawn, whose incredible journey into fitness began with a personal transformation at age 13. Overcoming significant weight challenges, he discovered a lifelong passion for movement. This journey led to a successful high school track and field career, cross country, cheerleading, and eventually a deep immersion into gymnastics, which he has been coaching since 2009. After college, Shawn’s athletic pursuits expanded to CrossFit, where they earned their CrossFit Level 2 Trainer certification and has been coaching since 2016. A true enthusiast of diverse movement, he even trained in Parkour during its early days and has been coaching it since 2015. Their extensive background in these disciplines means they truly understand the needs of our athletes and the functionality of our space. Beyond the gym floor, Shawn’s expertise as Facilities Manager is built on a strong foundation of practical experience, having grown up doing construction with his father and grandfather. This hands-on background ensures our gym runs smoothly, safely, and efficiently. When not ensuring our facilities are in top shape, Shawn is an avid reader, always enjoying both fiction and non-fiction concurrently; favorites include anything by Stephen King, sci-fi like Dark Matter, and self-help classics like The 7 Habits of Highly Effective People. He also brings a unique blend of academic and artistic talents, holding a BA in Mathematics and a Bachelor of Music in Classical Guitar performance from Sonoma State University. Adding to the impressive list of accomplishments, Shawn was president of Sonoma State’s archery club for three years and even placed fourth nationally in mixed pair collegiate archery. It’s safe to say Shawn brings a truly unique blend of skills and passions to our team!

Ron Benitez

CrossFit Director, Coach

Ron has always been into fitness and team sports, having played basketball in elementary, junior high, and high school. He also played football in high school, participated in outside recreational leagues, and was a cheerleader for his school’s competition squad—mainly focusing on partner and group stunts and tumbling. (He’d probably need a few months of practice now to show off that roundoff back handspring back tuck!). Ron was in the traditional Globo gym scene and was introduced to CrossFit in 2007. CrossFit Newport Beach came by his work to hold a Pose running and kettlebell clinic, and he has been hooked ever since. From 2007 to early 2009, Ron mainly participated in group WODs, and it wasn’t until summer 2009 that Ron began to spend time with the founder of CFNB, Melissa Metzke, where he shadowed her and volunteered his supervised coaching abilities with the adult classes, kids classes, and barbell classes. In late 2009, his corporate job took him to San Francisco, where he worked out at CrossFit San Francisco and began training with Diane Fu’s FuBarbell Club. In 2009, Ron tried out for the Team CrossFit Games. Although Ron did not make the team, he has always enjoyed the community and competitive atmosphere surrounding the tryouts. Life and work took Ron and his wife back and forth to Southern California and San Francisco between 2010 and 2011. Finally, he and his wife settled in San Francisco—she to open a small apparel boutique and he working back in the corporate world. Currently, Ron is helping with his wife’s store and focusing on fitness. Having been an athlete most of his life, his goal is to take what was a hobby and turn it into something more tangible, inspiring others the way his past coaches and CrossFit boxes have inspired him. Ron and Tricia have a little girl, Harlow Sloane, who was born on February 26, 2015.

Parkour Director, Parkour Coach

Kevin Bull

Management, Parkour Coach

Kevin grew up in Scotts Valley, CA. Most of his early athletic experience was based on informal tree climbing and exploring what the wilderness had to offer. At CSU Stanislaus, Kevin found success in running. He became an all-American in track and field, and was state champion in three disciplines. He graduated with a Bachelor of Science degree in Business Management.

Kevin was working in finance and in management when he found greater athletic success in the emerging sport of Obstacle Racing and the television show American Ninja Warrior. He’s been prominently featured since 2014, appearing on (and winning) 5 obstacle course competition shows over 6 seasons and counting.

Kevin launched and operated Dojo Boom (now Defy Thousand Oaks), a top of the line entertainment complex, for 2 ½ years. We are thrilled to have him join us at The Cave to further the business on both the back and front ends.

Auriyon Jacobs

Office Manager

Auriyon, also known as Auri, is the office manager here at The Cave. Everything from giving facility tours to finding the classes that fit best for you, Auri does it all! When she isn’t working, you can find her at a CrossFit class here, baking, or dancing it up! She is also a huge dog lover (new puppy alert! -2022).

She started gymnastics in the seventh grade, eventually working her way up to compete as a gold-level gymnast in the Xcel program. She is currently studying business at College of Marin. She loves going on adventures, seeing new places, hiking, and trying new food. She is constantly learning more about gymnastics so she can be a stand-out team coach!

Maxwell Mommsen

Parkour Coach

Maxwell was born and raised in the SF bay area and spent their enormous amounts of childhood energy running, jumping, and climbing on everything they could find. After trying numerous sports growing up, it was only natural that they would then fall in love with Parkour as the grass-roots movement began to gain popularity through the new medium of YouTube. Maxwell’s formative years as a Parkour athlete co-occurred with the burgeoning of this discipline, and many years were spent entrenched in the community learning from more advanced athletes and oftentimes discovering the potential of Parkour with friends of their own skill level. Max worked to help start a Parkour program in their home community before moving to LA to pursue degrees in Linguistics and Classical Languages & Civilisation. During their college years Max continued to fall deeper in love with various martial arts, quickly winning several area tournaments for Kung Fu and becoming an instructor at UCLA. This pathway solidified Max’s love of movement in general, and opened their eyes to the wide breadth of knowledge one could gain from such cross-training, adding things like Flow Arts (Juggling and Poi), rock climbing, dance, and even skateboarding to their repertoire. Having always had a passion for teaching, Maxwell has moved back to the Bay and decided to move into teaching movement full time, continuing to teach both Martial Arts and Parkour to students of all ages. Some of their current interests in expanding their own pedagogical method include incorporating mindfulness into their movement and teaching practice. When they aren’t teaching or training, Maxwell likes spending time with their dog Phoebe, creating through art and music, and keeping their research skills sharp through independent study.
