HOW IT WORKS
Beyond the Clinic
Raised in Pueblo, Colorado, Katrina’s passion for medicine and healing is deeply tied to her rural roots and her commitment to serving her local community. In 2021, she purchased a cattle ranch in Colorado and began exploring sustainable agriculture and soil health. This sparked her interest in the human microbiome, and how food, environment, and lifestyle directly impact long-term health and chronic disease.
