Our Core Values
Live and lead with purpose
We believe life is better when it’s lived with purpose. That takes a strong commitment to goals, passion for the work we do, and a boundless enthusiasm for spreading wellness around the world.
Pursue growth and learning
Coaches, like everyone else, are a work-in-progress, which is why we are lifelong learners who embrace a growth mindset. We keep our programs up-to-date with the latest scientific advancements and invest in continued self-enrichment.
Approach setbacks as opportunities
We put a positive spin on setbacks, choosing to treat them as opportunities for transformation. Change isn’t comfortable, and it’s certainly not linear. We welcome the chance to expand our limits.
Say no to the struggle
We believe the pursuit of health should be uplifting and feel good. That’s why our approach emphasizes tasty food, occasional indulgences, moderate and accessible physical activity, and above all else…FUN. So that your clients enjoy getting their health back on track!
Lean on each other
Transforming the health of the world takes a network of coaches supporting one other with guidance, information, and inspiration. We nurture connections in our growing community of Primal Coaches.
Achieve excellence free of expectation
We enjoy every step of the journey without getting caught up in expectations of how it should go or what the results should be, in our own pursuits and those of our clients. We strive for excellence while honoring balance, boundaries, and our very best.
