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!
