She worked in the not-for-profit healthcare industry, managing a national $165 million special event program. After choosing to be a stay-at-home mom when her children were young, Kristy earned her master’s degree in holistic nutrition. She focused her master’s thesis on the biochemical pathway of methylation. Since graduation, Kristy has taken a unique path, continuing to study epigenetics, nutrigenomics, and nutrigenetics specifically related to mental health. Kristy is in the final year of completing her DSc degree.

Kristy has established an integrative clinic in northern Colorado with a medical doctor, a doctor of traditional Chinese medicine, a neurosomotic specialist, and detox spa. She believes this integrative approach to chronic disease is key to delivering compassionate, comprehensive care.

As these new fields develop, nutrition’s key role in preventing and reversing chronic disease is undeniable. Kristy believes we are near the tipping point in healthcare when conventional medical providers recognize the need for evidence-based nutrition consultants.
