Amanda Norton
Athletics and CrossFit Director, Coach

Upside down and smiling—that’s how Amanda’s parents always found her as a little girl. By the age of four, after years of watching her flip around the house, Amanda was happily enrolled in gymnastics and was off to a lifetime involved in athletics.

Amanda found great success as a gymnast as she competed for over eight years, winning several impressive titles including a few State Championships and  one National first place on the floor exercise. Injuries became an issue for Amanda, so she slowly phased out of competition and into coaching.

She went on to study at UCLA and graduated with a degree in World Arts and Culture with a focus in Dance Studies. She found that dance could be used to help fill the void left by gymnastics. But, then came CrossFit…

CrossFit put Amanda back in the gym and reintroduced her to gymnastics. She now feels better than ever, with no injuries or lingering pain. She wishes she had CrossFit while she was a competing gymnast, because she feels she would have been better and stronger. As a coach, this offers her a unique perspective on how to help her athletes and develop well-balanced athletic programs at The Cave.

Amanda is currently the Athletics Director and a premier CrossFit and Gymnastics coach at The Cave, home to CrossFit Marin. Aside from her professional life here, she has stayed active in the community over the last eight years as a volunteer firefighter and EMT, as well as the Director of a free Jr. Lifeguard Program. She is currently in school to further her career in the medical field and also working hard to put her name on the map of the CrossFit community. Already making a mark as a 2012 and a 2014 Northern California Individual Regional competitor, Amanda is still smiling.

Amy Dockus
Operations Director

Growing up moving every couple of years, Amy figured out 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. 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 on their Northern California Disaster Action Team and as a First Responder for national disasters. 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.

JB Douglas
Parkour Director, Coach

JB was born in Southern California and raised in San Pedro. His mother, father, and brother are a big part of his life. Growing up, he experienced a constant need to challenge himself. He did this in many ways: gymnastics, skateboarding, sliding down the stairs in cardboard boxes, snowboarding, surfing, rope swings, basketball, baseball, swimming, volleyball, making up obstacle courses, climbing trees, and, of course, monkeying around. In high school, he focused on basketball and played four years on the varsity team for Palos Verdes High. He is still very close with his coaches and teammates from that time.

JB moved to Sonoma County in 2006 and attended Sonoma State University, where he earned a business management degree. In 2010, he started an internship as Director of Marketing at Rohnert Park Gymnastics, where they had a brand new parkour class. One thing lead to another, and when he graduated in 2011, it was clear his passions were movement and inspiring movement in others. JB believes that God has a plan for him, and it involves sharing these passions with others.

Since working at The Cave, JB has picked up slacklining and an interest in CrossFit. The Cave also helped him train for American Ninja Warrior seasons 4 and 5, where he made it to the finals in Las Vegas both times. During season 4, he fell on Stage 2 on the unstable bridge, and during season 5, he fell on the jumping spider in Stage 1 of Mount Midoriyama. He also tried out for ANW seasons 6 and 7. While he didn’t receive a call back, it didn’t discourage him from training and continuing to strive for total victory. Wish him luck, as he is always trying!

Russell Bruel
Facilities Director, Coach

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.

  • Level 1 CrossFit certified
  • 31 years of experience in the sport of Gymnastics
  • 21 years of coaching Gymnastics (recreational as well as competitive)
  • 7 years experience coaching CrossFit
John Main
Coach

John started at The Cave/CrossFit Marin in 2015, and we couldn’t be more excited to have him. His fitness story began with a career-ending soccer injury about one month into his freshman year at college. A skinny kid no longer able to run, he decided to get huge, tackling classic bodybuilding protocols, eating anything to gain fifty pounds and finally fill out the average T-shirt. Apart from loving fitness and the gym, he loved the purpose of guiding people’s dreams of themselves, so in 2002, he took a personal training position on top of his corporate day job.

In 2003, John found CrossFit during his relentless search for new training methods to use on himself and for his clients. Four search words led him to CrossFit.com: “body weight training” + “military.” There were no affiliates and few coaches then, so he bought some of the only bumper plates on the East Coast and devoured every video and article CrossFit posted. Finally, in 2005, he decided to teach full time.

John has been incredibly fortunate in his coaching career, as it has allowed him to work with trainers and athletes of all experiences and backgrounds. He opened Washington DC’s first stand-alone CrossFit gym, CrossFit MPH, in 2009, and he also helped open CrossFit Walter Reed, a gym built for adaptive athletes returning home with service injuries, at the National Military Medical Center in Bethesda, MD. Apart from also helping open CrossFit KLEW, a 40,000 square foot facility in Somerset, NJ, John also taught at Reebok CrossFit ONE at Reebok’s world headquarters in Canton, MA. Most recently before joining The Cave, he coached at the CrossFit Games while also being part of CrossFit HQ’s Seminar Staff, which allowed him to travel the world and instruct current and aspiring trainers.

Chelsea McAlexander
YSC Director, Coach

Chelsea moved to the Bay Area from Columbus, Ohio in 2014.  She loves learning and growing as both an athlete and a coach in new, fun, and challenging ways. She believes movement variety is the spice of life!

She has a passion for inspiring others, not only in fitness but also in personal empowerment, developing new habits, behavior modification skills, and truly falling in love with movement. She specializes in helping develop a growth mindset in people of all ages.

Chelsea has a degree in Dietetics (Nutrition) from Columbus State in Ohio. Prior to moving west and joining The Cave, she worked for five years at the Public Health Department and at Ohio State University, doing child and family nutrition counseling.

Chelsea started teaching swim lessons to young children when she was fourteen and has been working with children and teenagers in a wide variety of sports and activities ever since.

Chelsea’s athletic background is in strength sports. She started lifting competitively in high school and has competed, on a national platform, in Olympic Weightlifting, Powerlifting, and Strong(wo)men competitions. She also has dabbled in competitive CrossFit, swimming, volleyball, and shot put. She is also passionate about and actively involved in gymnastics, mountain biking, surfing, yoga, hiking, snowboarding, and kayaking.

Stephanie Ring
Coach

Movement has always been an important part of Stephanie’s life, starting with ballet at age three and moving to competitive cheerleading at age sixteen. She started practicing yoga in college, but it was years later (when she started training for triathlons) that she took this practice to the next level. Concurrently, she competed in more than a dozen races, including two marathons, a century ride, and two Half Ironmans. Eventually, her love of endurance sports began to wane. It was then that her interest in gymnastics and CrossFit started to grow. When she was introduced to CrossFit in 2013 at CrossFit Marin, it wasn’t long before her training days outnumbered the days on the yoga mat. It was around this time when she created WOD Recovery Yoga, a yoga practice designed to help athletes recover mentally and physically from training. She now coaches full time, both at CrossFit Marin and at yoga studios in San Francisco.

Dan Petersen
Coach

Daniel is a lifelong athlete and has competed in several disciplines including baseball, basketball, running, and cycling (among others). After turning his love of sports into a passion for sharing his athletic experience with others, he began coaching at the local Boys and Girls Club and continued this for several years. Recently, he has coached basketball and cross country at the junior high level, a 12U travel baseball team, and baseball at his local Little League.

NASM Certified Personal Trainer, NASM Youth Exercise Specialist, and a USAW Level 1 Sports Performance Coach

Ron Benitez
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.

Erin Ballantine
Coach

Erin Ballantine was a competitive gymnast in her youth and started coaching at a young age to help pay for her competitive seasons. After discontinuing her own training, she continued to teach children and assist in the junior elite training program at her home gym. Since that time, Erin has accumulated over twenty years of experience as a gymnastics coach. She is a USA Gymnastics professional member and  certified instructor, and her experience ranges from teaching Mommy & Me classes to training Level 9 competitive gymnasts. Erin spent several years doing community outreach work in the Bay Area, traveling to low-income communities and teaching gymnastics to kids who would not be able to afford it otherwise. She has coached at a number of gymnastics schools in the area and spent over eight years managing and teaching at Cal-Star Gymnastics in Novato. Erin started teaching at The Cave many years ago but only recently came on as a full-time employee. She coaches recreational and competitive gymnastics and is proud to be a member of the incredible staff here.

Outside of the gym, Erin has returned to school to pursue a degree in occupational therapy. Her hope is to work with children who have a challenging time with mobility and physical activity. Although she has a ways to go in pursuit of this degree, she has already spent time working with physically challenged kids and has found the work rewarding and inspiring. She, herself, enjoys all types of physical activity, including hiking, biking, CrossFit, wake-boarding, running, snowboarding, and skiing. She enjoys traveling, reading, and—most of all—exercise!

Kyla Neugebauer
Coach
Josh Morris
Coach

Josh is originally from Montana but has been living in California for the past six years. He grew up with a strong connection for nature and movement, started gymnastics at an early age, and finally found Parkour at age thirteen. He has been doing it ever since and loved it every day. Josh is now attending College of Marin with the goal of transferring to UC Davis with a double major in Graphic Design and Psychology.

Roland Turner
Coach

Born and raised in Marin County, Roland has always been active in sports. Through his childhood, he tried every sport from tennis to football but never found the perfect fit. At thirteen, he discovered parkour through a local paper advertising a program to become a “ninja.” He has been practicing ever since. Roland has been interested in teaching this discipline ever since he began training, and he joined The Cave’s team when he moved back to Marin County from San Francisco. He loves to develop applicable strength and creative focus, and he finds parkour very motivating due to the possibility of visible progress. Roland loves the outdoors and music, as they both inspire movement. Outside of The Cave, Roland is a drummer and spends time recording with friends and making music on his computer.

Andrey Pfening
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.

Daniel Machado
Coach

Daniel has lived in Marin County his whole life and cannot remember a time when he was not passionate about movement. As soon as he found Parkour, he could not get it off his mind. Since starting training here at The Cave, he has used the practice not only as a way of movement but also as a tool for overcoming life’s obstacles. Daniel joined The Cave as a Parkour coach in February 2016.

Matthew Beier
Administration

Born in Duluth, Minnesota, Matthew joined The Cave’s administrative team in 2014. He attended film school at Chapman University in 2003, where he studied screenwriting, film production, and English before spending a final semester abroad at Victoria University in Wellington, New Zealand. Apart from being a fitness and nature enthusiast, he is a novelist, screenwriter, photographer, and graphic designer. In 2012, Matthew published his first novel, The Breeders, and in 2014, he began publishing his seven-book Jonathan Flite series, which thus far includes The Confessions of Jonathan Flite (2014) and The Release of Jonathan Flite (2016). He is currently writing Book 3 of the series, The Rise of Jonathan Flite, and developing his first feature film.

He cultivated a love for backpacking, hiking, and the outdoors while in New Zealand, and he currently participates in CrossFit classes here at The Cave. Joining our facility was a huge bonus for Matthew, as it opened up many new roads toward fitness for him.
