About Kourtney

Hey there, it's Kourtney. I'm a functional nutritionist (BS, CNC, FDNP) who specializes in helping women bring balance to their bodies through food. After years of experiencing chronic health struggles, I was tired of the quick fixes, medications, and doctors telling me that "everything was fine", despite feeling my worst. Through a friend's suggestion, I discovered functional nutrition and lab testing, and my outlook on health was never the same. Through years of research, mentorship and functional training, I discovered answers to the hormone, gut, and immune issues I had been struggling with for years. I lived much of my life thinking that healing was out of reach, when in fact, Western modalities were simply failing me. Thanks to functional labs and individualized nutrition, I was able to overcome both a PCOS and Hashimoto's Thyroiditis diagnosis - and now, years into remission, I am thankful to now help women (read their stories here) find balance in their health through data driven, evidence based approaches that meet them exactly where they are. I believe that there is always an answer, and that solutions are rarely far away - even when you can't see through the fog of disappointment and confusion that health struggles can bring. If you're ready for real health changes, my team and I are there to support you every step of the way. 

Evidence-based lab testing drives our decisions in your care as we support your body through food and targeted supplementary approaches. During your time with Kale Diagnostics, you are paired with an experienced nutritional practitioner who will thoroughly address labs, nutrition, and lifestyle factors with you in a hands-on setting. The whole team is here to support you, as your assigned practitioner reports back to the team to confirm and review the best plan of action for you.

Group Coaching

Group coaching is the most affordable way to access lab testing, extensive health education, and an impactful level of 1:1 support. Through a community-style setting, you will learn the ins and outs of health, while being provided with extensive resources that will support your health long-term.

Starting at $399/month or $2094 paid in full Apply Here

Get ready to learn, connect and begin overcoming your health struggles by following the Kale Diagnostics framework: labs, data, and research-based solution implementation. With over 20 hours of intentional education, introductory 1:1 practitioner support, and included functional labs (1k+ value), Kale Diagnostics Group Coaching is the perfect place to start or up-level your health journey.

High Level 1:1

Sometimes complex health struggles require more intensive support with an even deeper dive into individual health data. Through 1:1 coaching, extensive functional lab testing, and intensive one-on-one calls, your dedicated Kale Diagnostics practitioner leads you through your health journey in a private, highly supportive setting.

Starting at $575/month for 9 months of support

Apply Here

The main factors that set high-level 1:1 apart from group coaching are the additional functional lab tests and the 1:1 support you receive from your practitioner, which includes private coaching calls and extensive private messaging support. All high-level 1:1 Kale Diagnostics Practice Members automatically receive access to Kale Diagnostics Group Coaching, where they learn and experience support in an intentional group setting.

"It has been through them believing in me that I began to believe in myself and my capabilities of taking control of my health. Kale Diagnostics' approach and guidance was individualized to my specific needs, and my practitioner guided me every step of the way with thorough meal planning, supplementation, and loving conversation. It is with their help that I have regulated my cycle after years of irregularity, learned to treat food as medicine rather than an enemy, and have become the healthiest I have been in years. I cannot recommend working with Kale Diagnostics enough. Their heart and sincere care for every one of their clients is incredible and they are the best team you could ask for when choosing to re-claim your health as a top priority in your life."

We Assess Your Health

Based on your level of need, the Kale Diagnostics Team suggests which plan of action is best for you. Are you a candidate for group coaching with one call and two labs, or are you a candidate for more practitioner guidance and more labs?


We Gather The Data

Once you welcome us to your journey, we mail functional lab tests and request that you complete those at home, along with a detailed health history form. Once we have your health data, we create your health protocol, and you meet with a Kale Diagnostics practitioner to review labs and go over the plan of action that the team has agreed upon. Each time a new lab is back, protocol edits are made to match your needs.


We Support Your Unique Needs

We monitor your progress to ensure you can be successful with as little sacrifice or struggle as possible. We believe wellness should be an enjoyable and results-driven journey. We work alongside you until you are equipped enough to thrive on your own.
