A note from Susan…

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 133 million Americans – nearly half the population – suffer from at least one chronic illness. So, obviously, the status quo in medical and nutrition support isn’t enough!  

Our public is ready for alternatives. They want 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…are you seeking a way to offer more effective support in your work with clients? 

One Size Does NOT Fit All Anymore!

Functional Medicine has answers – answers that rely heavily on Nutrition know-how at a whole new and much deeper level. Our public needs your support and Functional Medicine doctors need more specialty-trained nutritionists to assist their patients.

You don’t need to be in private practice to provide this rich support, though these days, starting an (even small) virtual practice is easier than ever!

So, how confident are you with your knowledge of biochemistry, dietary and herbal supplements, Functional Medicine labs, and immune physiology? (And that’s just the start)


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 that many years ago and now I want to help you do the same. Learning and practicing functional nutrition 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. It’s also offered me the income level I deserve, without having to work tirelessly to earn it. Just as this has been for me, I know it can also be for you! Join me on a learning journey that will help you fall in love with what you do again!

Functional Nutrition Perspectives on Gut Health

Registration now open! Series starts June 6th, 2024!

From digestive disorders and intestinal dysbiosis to intestinal permeability and allergens, gut dysfunction compromises a patient’s health and diminishes vitality. It makes sense, then, why it’s often the first place to start improving overall health. While this is a nutrition-focused course, it’s definitely more than simply recommending more fiber and probiotic-containing foods.

This advanced course will supply you with the background, insight, and in-depth clinical thinking to confidently assess and treat 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 diet and natural support approaches you’ll need to help your clients regain optimal health and vitality.

Functional Nutrition in ADHD and Autism Spectrum Disorders

*** Registration for this course is currently closed. If you want to be notified when we open another course, please request to be on our waitlist HERE!***

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 under the umbrella of autism spectrum disorders (ASD) and potential, contributing factors for ASD development. The critical roles of methylation and genomics, oxidative stress, gastrointestinal function, microbiome, and the immune system will be explored in depth.

You will be provided comprehensive coverage of the clinician’s role in the management of 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.

Supplement Savvy: Everything You Need to Know to Become an Expert in Dietary Supplements

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 to best determine our patients’ needs for supplementation and provide the basis for responsible recommendations. Likewise, the importance of follow-up to adjust recommendations over time.

Adrenal Health: Optimizing Support for Energy, Sleep, and Wellbeing

*** registration for this course is currently closed. If you want to be notified when we open another course, please request to be on our waitlist HERE!***

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 lacking 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 properly assess your clients to know exactly where the imbalances lie and how to responsibly provide targeted support. 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

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 your 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

*** registration for this course is currently closed. If you want to be notified when we open another course, please request to be on our waitlist HERE!***

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 while you can’t change your genetics, we do 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 just know what to do!

A Functional Nutrition Focus on Thyroid Health

Conventional medicine has predictable answers for thyroid disease, but unfortunately, there remain clients with 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 support of thyroid health can be achieved. Help your clients find the missing pieces and achieve vibrant health once and for all!

Hormone Health

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 really 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 just know more. 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!

Histamine Intolerance and Mast Cell Activation Syndrome (MCAS)

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!
