What We've Helped With

About Kale Diagnostics

Why We're Different

Our approach is rooted in functional medicine, a science-driven practice that views your health as a complex, interconnected system. Modern medical care is rarely unified, with various specialists lacking communication and understanding of your specific needs and treatments. We provide the most reliable and affordable access possible to a method of care that leaves no stone unturned as we explore your unique biology. 

Your health symptoms deserve a long-term solution instead of a temporary fix. While modern medicine has brought many advancements, it is all too often missing the mark when it comes to genuine healing. We understand the pathology of disease, and we utilize the medicinal mechanisms found within nature to provoke change in your bodily systems. We draw upon the clinical correlations found in your unique health data to make the best suggestions for your health. If you crave cautious care that prioritizes your safety and ultimate wellbeing above all else, you are in the right place. 

We are here for you throughout every twist and turn of your health journey. When you become a client, we address immediate symptoms while also building a resilient foundation for lasting wellness. We're not after a quick fix: we are here to help you build a health body to support you for the long-haul. 

With us, you are heard, validated, and understood. Empathy drives the connection we share, and you can rest well knowing that we will never dim our commitment to your highest good and ultimate wellbeing.

To Your Health,

With Kourtney’s deep expertise in functional medicine and Stephen’s primary experience in healthcare—including telemedicine, health shares, and managing health and wellness platforms for industry clients, including Gallagher Affinity—they understood the shortcomings of conventional healthcare.
