Facilities Director, Coach
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.
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.
Cosmo Ocegueda
Youth Strength & Conditioning Manager, Coach
Cosmo fell in love with sports at an early age. He was drawn to the element of competitionand the camaraderie that comes with it. He played on a traveling baseball team and when he wasn’t playing ball, he was outdoors with his friends skateboarding. After sustaining a wrist injury, he switched gears and picked up running, which eventually led him to compete on the San Francisco City College Cross Country team.
Cosmo spent many years training in endurance sports. With the desire to pick up a new challenge, he jumped headfirst into strength training and CrossFit. He is currently pursuing a Bachelor’s degree in Kinesiology/Personal Training at San Francisco State University.
Den Bell
Men's Gymnastics Team Head Coach
Den has been active in the outdoors since he grew up on a farm in Wisconsin. He began lifting weights at 16, and working out became a part of his daily routine. He graduated from the University of Wisconsin with a Bachelor’s Degree in Fine Art, and photography has threaded through all the different careers he has explored. At age 40, he found himself in the best shape of his life and found himself onstage in a bodybuilding competition.
At The Cave, Den left the bodybuilding world behind and focused solely on gymnastic bodyweight strength and movement, and realized that he may have been worshiping the wrong god all his life. Den has photographed many annual events such as the parkour Pitfall competition and the Crossfit Throwdown.
He currently spends his time as a coach for the Boys Gymnastics Program at all levels and is passionate about helping students who are focused and deliberate in their gymnastics training. He is honored for the opportunity to work alongside the Cave’s incredible staff to make this a reality.

Andrey Pfening
Parkour Manager, Parkour Coach
Andrey Pfening was born on March 11th, 1990 in Samarkand, Uzbekistan. He spent his childhood in Samara, Russia, and at the age of twelve moved to America. He has resided in the San Francisco Bay Area ever since.
While in high school, Andrey came across a YouTube video of David Belle (co-founder of Parkour). He was instantly drawn to the activity and began seeking out knowledge and experience, practicing with friends and dedicating himself to training on his own several days a week. As he gained proficiency, others were drawn to his abilities and attracted to his teaching style.
Andrey has now become a recognizable member of the Parkour community. He helps orchestrate local monthly jams in San Francisco and is committed to educating himself about Parkour and the most effective teaching tools. He frequently attends local and national parkour summits, with well known practitioners, which review the most up to date trends in the discipline and how to implement these trends into his teachings.
Outside of the gym, Andrey spends a lot of time coming up with skill progressions, class outlines, and visual aids, which assist his physical and vocal style of teaching. He uses video of himself and his own students to break down progressions, frame by frame.
Annually, Andrey performs in live performances, working with local choreographers such as Scott Wells, Zoe Klein, Natasha Kaluza, and others. In 2015, he had a rare opportunity to be part of a massive San Francisco Opera production “The Trojans.” And in 2016, he will be part of the San Francisco Opera’s “Carmen” production. He also periodically choreographs and performs pieces of his own.
Kevin Bull
Parkour Coach, Management
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.

She played competitive travel soccer for 10 years and has a State Cup win under her belt. Lexi enjoys working as a sportscaster for her university’s radio station, going to National Parks, and taking her dogs on hikes. She will be graduating in May 2018 with a BA in Communication and Media Studies and a BA in History. Since her start with The Cave’s Events staff in the summer of 2016, Lexi has fallen in love with the creativity and freedom of parkour.
Russ started working at The Cave in late 2006 and has happily been part of its growth since then. Apart from teaching movement education to two and three year olds (while they learn how to jump, roll, lift, and land safely) to coaching Gymnastics, Russ has mentored young children and teens so they can approach life with confidence through physical accomplishment.
Russ also coaches adults in both CrossFit and Gymnastics and particularly enjoys helping those who have never approached either sport. That said, he also enjoys all types of fitness enthusiasts The Cave attracts, from ex-athletes who strive for excellence and love to test and retest their athleticism, all the way to the average Joe/Jane wanting to get off the couch and get in shape. His approachable and patient nature, love for the moment, and enthusiasm for what the body is capable of achieving drives him every day to pass on that knowledge to whoever crosses his path.
Whether it be Gymnastics, CrossFit, or Parkour, his lifelong experience with understanding the human body allows him to teach movement to all who enter The Cave in a progressive, safe manner.

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.
