• Practitioners, do you want help analyzing functional lab results and developing treatment plans?
  • Industry leaders, is your company developing an innovative oral health product?
  • Are you a patient who wants a consultant on your side to help guide your way, analyze your results, and look for hidden root causes of your chronic illness?

No need to look any further. We offer consulting services to laboratories, clinicians, industry leaders, and patients to help alleviate these pain points.


We know that they don’t teach functional medicine in school, much less functional laboratory testing or how to design a treatment protocol. Integrative and functional medicine is something you learn once you’re out of school. Testing and developing customized protocols will help you deliver world-class functional medicine care to your patients resulting in happier and healthier patients.

It will help you solve the toughest chronic illnesses, increase your referrals, and increase your revenue. But do you have the time to learn it? Are you getting the personalized help you want from your post-grad educational programs? Or do you simply want verification that you’re on the right track before you move forward with your treatment recommendations?

Cass Nelson-Dooley, MS has over fifteen years of experience teaching clinicians about integrative and functional laboratory results. She helps practitioners examine root causes, interpret complex test results, and design natural treatments to improve health. She has worked as a medical educator at Metametrix Clinical Laboratory, Genova Diagnostics, Dunwoody Labs, and Diagnostic Solutions Laboratory.

Building Innovative Oral Health Products


If you are navigating a chronic illness and need assistance, we can help you. There are not enough practitioners in the US who are knowledgeable in integrative and functional medicine. They may not be in your area or they may be outside of your budget.

Cass can be an expert member of your healthcare team; reviewing your lab findings and clinical history, working with your healthcare practitioners, and helping you get on a path to optimum wellness.

Don’t ignore your symptoms and don’t accept “there’s nothing we can do.” You can reverse chronic illness when you have the right medical team and you use a functional and integrative approach to address the root causes of disease.
