Kristen Barnes, Director of Operations


Instructor: CrossFit, Gymnastic Strength Training

Certifications: CrossFit Level 1, GymnasticBodies Athlete


Kristen started CrossFit in the Summer of 2014, after having her second child- very doubtful if she would continue with it.  Her opinion quickly changed after spending some time in the Box. As a Special Education teacher, she is impressed with CrossFit's adaptability of each workout to fit every person’s abilities- regardless of age, skill or mobility.  Equally impressive, is the supportive community embracing everyone that comes through the door.  For Kristen, CrossFit contributes to permanent positive changes to one’s health, sleep and nutrition.  Kristen believes that not only does CrossFit change one’s body, but also instills an inner confidence about what is still possible.

Adria Bishop


Instructor: CrossFit, Mobility

Certifications: Crossfit Level 1, Certified Crossfit Mobility Coach

Adria never saw herself as an athletic person when younger, but joining CrossFit Sebastopol completely changed her perspective.  She fell in love with CrossFit and the community it creates in 2014. Adria loves the variety of workouts and discovering how the human body is capable of so much more than what imagined. Adria believes that CrossFit is truly for anyone at any stage of life or fitness level and conveys that belief through her coaching.

Jesse Barnes


Instructor: CrossFit, Gymnastic Strength Training

Certifications: CrossFit Level 1, GymnasticBodies Athlete


Jesse is among the first members of CrossFit Sebastopol and loved it immediately.  Jesse reads extensively on nutrition and health physiology, and discovered his missing link was an exercise program keeping him interested while also improving his health. The CrossFit combination of lifting, gymnastics movements, and metabolic conditioning fills the void left by other ‘exercise programs’.  His athletic background is fairly limited, including some high school cross country and track, but Jesse immediately took to weight lifting, becoming fascinated with programming, stimulus and response, and the mechanics of the lifts themselves.  Jesse’s interest in performing body weight movements inspired him to attend a GymnasticBodies seminar in 2016, eager to bring rigorous, intelligent progressions and joint "prehab" to CrossFit Sebastopol.

Ginger Kelly


Instructor: CrossFit

Certifications: CrossFit Level 1, CrossFit Competitors Course


Ginger has always been an active person enjoying yoga, running and a sporadic relationship with gyms.  Ginger admits to not knowing about CrossFit until March of 2015, after she ran into a friend and was amazed by the transformation of her friend’s body and spirit.  Ginger attended a class, and although she found it both mentally and physically challenging,  her sense of accomplishment and the realization of her own capabilities fulfilled her.  Ginger’s enthusiasm for the sport is contagious and she is excited to share her knowledge and motivate others!

Jean-Luc Koelemeijer


Instructor: CrossFit

Certifications: CrossFit Level 1


Jean-Luc has an extensive background in sports.  He was a ski instructor in Switzerland while attending University of Geneva. He also coached swimming for kids and adults.  He played rugby competitively in France throughout high school and University.  After moving to the US, Jean-Luc prioritized work and family over fitness and, like most of us, gained a few pounds.  The birth of his second daughter in 2010 sparked his desire to get fit again and he discovered CrossFit.  Through the CrossFit community, he rediscovered the camaraderie and the competitiveness he experienced when playing rugby and the joy of "leaving it all out on the field".  Jean-Luc looks forward to sharing his love of Crossfit with everyone he meets!

Traci Monaghan


Instructor: CrossFit, Barbell Club

Certifications: CrossFit Level 1, USAW Level 1, Certified CrossFit Mobility Coach


Traci first found fitness as a child chasing after her older brothers in any sport possible, but usually as the designated ball "fetcher".  She continued to play sports until high school when she focused solely on volleyball. After college, and no longer involved in organized sports, she became a ‘cardio junkie’, completing multiple half- and one full-marathon. She found CrossFit over 4 years ago as a way to add strength training to her endurance training. She fell in love with the sport after seeing how CrossFit and Olympic lifting can push the body beyond what was believed to be possible. She has now traded in her running shoes for a barbell, and is now happiest with a barbell in her hands. Her experience as a Certified Massage Therapist has complemented her coaching, as she has a deep understanding of the body and how to assess and improve/correct movement patterns. As a coach, she loves seeing people meet--and often exceed--their goals.
