Meet our Founder
Hi, I am MariahJo
As a proud US Marine, my life has been dedicated to discipline, strength, and the relentless pursuit of excellence. But beyond the uniform, you'll find me chasing adrenaline in the great outdoors, whether that's lifting barbells or carving down mountainsides on my snowboard. "Barbells and Boards" isn't just our slogan; it's a lifestyle that embodies the thrill of pushing limits and embracing the beauty of hard work.
The spark for Killa Co. ignited from my deep-seated passion for fitness and the transformative power of doing hard things. This journey has taught me that true strength is forged in the furnace of challenge, and it's a lesson I'm here to share with you. Killa Co. was born from the belief that everyone has an inner warrior waiting to be unleashed, and our mission is to be the catalyst for that transformation.
Join us as we embark on this journey together, pushing past boundaries and discovering what we're truly capable of. Welcome to the family. Welcome to Killa Co. Let's make greatness happen.
