This is like no other time in history. Health is a priority to our public like never before. Yet, at the same time, it’s estimated nearly half the US population suffers from at least one chronic illness. That’s pretty clear evidence the status quo in medical and nutrition support isn’t enough!
Our public is ready for alternatives. They want answers they aren’t otherwise getting – lasting solutions, not band-aids. They want advice from credible sources—truly personalized advice. The focus is high on disease prevention and more natural health support options.
Ask yourself…do you want to be the practitioner with the answers, the one offering more natural, effective, and personalized support? Of course you do! So, then, it’s time to rethink what you know…
One Size Does NOT Fit All Anymore!
The Functional Medicine approach is personalized! Solutions rely heavily on nutrition know-how at a whole new and deeper level. Here’s where nutritional biochemistry comes full circle into application. It’s definitely more than just a good diet. Genomic influences may also factor in. Get yourself up to speed because our public and functional medicine doctors alike need specialty-trained nutritionists, and that should be you!
So, how confident are you with your knowledge of biochemistry, dietary and herbal supplements, functional medicine labs, the microbiome, mitochondrial function, immune physiology, and more?
It’s Time to Be Part of the Solution!
You’re in the right place if you want to become the expert resource needed now more than ever. If you’re ready to transform your career and have incredible opportunities for success more than you’ve ever known, you’ll need to fill in the gaps in your education. I did just that many years ago and now I want to help you do the same.
Learning and practicing integrative and functional nutrition medical nutrition therapy (IFMNT) has allowed me to have a tremendous impact on my clients while at the same time offering me the freedom and flexibility to be the practitioner I always wanted to be. Just as this has been for me, I know it can also be for you!
If you want to help more people, especially those who struggle to find answers, if you want to have higher income potential without having to work endlessly for it, and if you want the freedom to practice at a whole new level, then join me on a learning journey that will help you have it all and, best of all, fall in love with what you do again!

Decoding Thyroid Dysfunction:
A Functional Medicine Approach
Registration Now Open – Live Sessions Are Already Underway!
Conventional medicine has predictable answers for thyroid disease, but unfortunately, there remain clients with a subclinical presentation that often goes undetected or unattributed to thyroid dysfunction. Even those considered adequately medicated can still present with symptoms. Worse yet, many are told their thyroid isn’t the problem, but if looked at more deeply, there indeed is a connection to the thyroid!
By applying multiple aspects of Functional Nutrition, more in-depth thyroid health support can be achieved. Help your clients find the missing pieces and achieve vibrant health once and for all!
Functional Nutrition Perspectives on Gut Health
ON-DEMAND Training Available Now!
Become a gut health authority! From digestive disorders and intestinal dysbiosis to intestinal permeability and allergens, gut dysfunction compromises a patient’s health and diminishes vitality. It makes sense why it’s often the first place Functional Medicine practitioners start with to improve their patients’ overall health. While this course is nutrition-focused course, it’s definitely more than simply recommending more fiber and probiotic-containing foods.
This comprehensive training will supply you with the background, insight, and in-depth clinical thinking to confidently assess and support patients who may present with conditions, signs, and symptoms indicative of gastrointestinal dysfunction and microbiome imbalance. We will discuss in detail the important laboratory evaluations often utilized by functional practitioners, the appropriate clinical connections, and effective evidence-based dietary and natural support approaches you’ll need to help your clients regain optimal health and vitality.

A Balancing Act: Mastering Hormone Health for Optimal Wellness
*** Registration for this course is currently closed. If you want to be notified when we open registration again, please request to be on our waitlist HERE! (Be sure to mention the course name)***
Millions of women live their entire lives believing the myths that they have to not only live with but accept irregular, heavy, and painful periods, mood swings, weight gain, infertility, fatigue, and more as a normal part of life. Men get the same story for their hormonally-related issues – and hey, there’s a pill for that – never mind the root cause!
Unless you’re a doctor, your professional training doesn’t equip you with the know-how to evaluate or assist your clients in this area of health. Don’t be intimidated – the truth is, there’s a LOT you can do if you know more. Nutrition has a more significant role than you think. Imagine if you helped them get to the root cause of their health issues…maybe this is a personal issue, and you’ll be able to help yourself, too!

Unlocking the Power of Organic Acid Testing to Transform Your Practice
*** Registration for this course is currently closed. If you want to be notified when we open registration again, please request to be on our waitlist HERE! (Be sure to mention the course name)***
The Organic Acids Test (OAT) is the single most significant functional test that every health care practitioner should know how to interpret and use in their practice.

Functional Nutrition in ADHD and Autism Spectrum Disorders
ON-DEMAND Training Available Now
Both ADHD and ASD are neurodevelopmental disorders (brain development has been affected in some way). That means both conditions/disorders affect the central nervous system, which is responsible for movement, language, memory, and social and focusing skills. ASD has many similarities to ADHD, but there are also differences between the two.
In this informative training, we’ll examine the various subtypes of autism spectrum disorders (ASD) and potential contributing factors to ASD development. We will also explore in depth the critical roles of methylation and genomics, oxidative stress, gastrointestinal function, microbiome, and the immune system.
You will be provided with comprehensive coverage of the clinician’s role in managing ADHD/ASD disorders, including implementing specialty diets, diet dos and don’ts, interventions for difficult eating behaviors, and supplemental support options. Various adjunct therapies will also be explored.
New Perspectives on Metabolic Disorders:
Obesity, Diabetes, & Cardiovascular Health Through the Functional Medicine Lens
ON-DEMAND Training Available Now!

The Functional Nutrition Intake:
ON-DEMAND Training Available Now!
Discover root-cause assessment parameters that lead to more targeted recommendations, better outcomes, and more client visits!
Do you ever feel like something is missing when working with your clients? They’ve begun to make changes and are seeing some results but something’s missing…they’re still struggling to meet their health goals or to see the full resolution of their symptoms you and they expected.
Functional Nutritionists look at cases differently and in many cases, this brings more success!
The Integrative and Functional Medical Nutrition Therapy (IFMNT) assessment dives deep leaving no stone unturned! The unique makeup of each patient is considered, along with both internal and external factors that affect overall health and vitality. Genetic influences are also key to a deep understanding of each client. Together, all of these factors contribute to your most personalized recommendations that help to ensure the most successful outcomes in even your most challenging cases.
Supplement Savvy: Everything You Need to Know to Become an Expert in Dietary Supplements
ON-DEMAND Training Available Now!
Our conventional nutrition education has prepared us well in key areas like general anatomy & physiology, lifecycle nutrition, macro and micronutrients, body systems; cardiovascular, blood sugar, liver, digestion, etc, and of course, specialty medical and overall healthy diets. The emphasis is on getting nutrition through a good varied diet; one that provides the RDAs for all the essential nutrients. But what about when diet and RDA standards aren’t enough?
In this training series, we’ll explore assessment modalities, including laboratory biomarkers and clinical signs/symptoms, that aid us in determining our patients’ best needs for supplementation and provide the basis for responsible recommendations. Likewise, we’ll discuss the importance of follow-up to adjust recommendations over time.
Adrenal Health: Optimizing Support for Energy, Sleep, and Wellbeing
ON-DEMAND Training Available Now!
When adrenal glands don’t produce enough hormones, this can result in adrenal insufficiency (Addison’s disease). Short of a frank diagnosis, though, many with prolonged stress exhibit signs of what is commonly referred to as mild adrenal insufficiency or “adrenal fatigue”. While not a medical diagnosis, symptoms can be quite significant for some. Do you know the best support? The lack of sensitivity in typical blood tests presents a challenge and leaves many unable to connect to the real root cause. What tests should you do instead?
This training provides deep coverage of the adrenal system so you can adequately assess your clients to know precisely where the imbalances lie and how to provide targeted support responsibly. You’ll identify the root-cause culprits while helping your clients mitigate common stressors in their lives to regain vibrancy once again!
Nutritional Implications of Methylation
ON-DEMAND Training Available Now!
The Methyl Cycle is the backbone of our physiology. Its functional status determines our susceptibility to environmental toxins, hormone balance, cardiometabolic health, stress resistance and so much more! Sure, we learned about it in school, but we never really learned how to apply it in practice!
Methylation is a confusing array of biochemistry, but suffice it to say, a defect at any one point in these interlocking cycles will inevitably affect the remaining pathways, and your overall health will then suffer.
Among diet, environmental, and lifestyle influences, genetics can be the culprit in methylation dysfunction. While we cannot change our DNA, if we know the weak links we can create “nutritional workarounds” – we can supplement alternative pathways or withhold from our diet molecules that work against us.
If we don’t address the Methyl Cycle abnormalities that underlie unexplained or chronic illness – well then, the illnesses will remain chronic and unexplained, because it is the Methyl Cycle Abnormalities that predisposed us to ill health.

The Functional Nutrition Approach to Cancer Prevention and Support
*** Our next live series will start in May! If you want to be notified when we open registration, please request to be on our waitlist HERE!*** (be sure to list this course name in your request)
It is estimated that around one-third of deaths from cancer are due to tobacco use, high body mass index, alcohol consumption, low fruit and vegetable intake, and lack of physical activity. Likewise, we know many cancers can be cured if detected early and treated effectively.
Functional Medicine professionals recognize that while you can’t change your genetics, we have a lot more control over the expression of our genetics than we ever thought before. By assessing for underlying root-cause issues and addressing patient care from a systems biology framework, they know that preventing or changing a cancer-permissive milieu is a game-changing approach!
Yes, you can dramatically reduce the chances of getting or dying from cancer if you know what to do!

Biotoxin Illness
*** Registration for this course is currently closed. If you want to be notified when we open registration again, please request to be on our waitlist HERE! (Be sure to mention the course name in your request)***
Mold and its toxins (mycotoxins) are at the root of many chronic illnesses and immune dysfunction. Too many people suffer from mystery illnesses FOR YEARS only to be told, “just take these meds.” And they STILL don’t feel well! There is a serious lack of clinicians especially nutritionists/dietitians trained to help those with biotoxin Illness. This course will bring your knowledge of toxicity and detoxification full circle so you can practice at the highest level to best serve your clientele with their most challenging health concerns!
Histamine Intolerance and Mast Cell Activation Syndrome (MCAS)
*** Registration for this course will open this June. If you want to be notified, please request to be on our waitlist HERE! (Be sure to mention the course name in your request)***
Histamine intolerance manifests in up to 3 – 6% of the population (with a prevalence in children and as much as 80% in middle-aged women), but how much is unidentified or unreported considering the rapidly increasing number of those who suffer?
Patients struggle with the conventional recommendation of antihistamine medication with unwanted side effects and restrictive histamine avoidance diets. If it’s not a typical histamine reaction, they get other medications (sometimes several). They want more than medication and diets; they want solutions to alleviate the problem in the first place!
