For Health Practitioners ready to move beyond symptom management to root-cause care

A Professional Pathway to Practice Functional Medicine.

ROOTED is a 30-week functional medicine certification for health professionals who want to understand the physiology behind chronic symptoms, interpret labs with greater confidence, and build personalized plans that make sense for the person in front of them.

Whether you are beginning your functional medicine education or have completed previous training but still struggle to apply it, ROOTED gives you the structure, tools, and practical guidance to practice with greater clarity and confidence.

Whether you are beginning your functional medicine education or still struggling to apply previous training, ROOTED gives you the structure, tools, and mentorship to practice with greater clarity and confidence.

You Know There Has to Be More

You recognize that symptoms rarely exist in isolation — but you need a clearer system for connecting them.
You want to identify meaningful patterns across symptoms, history, lifestyle, and labs before dysfunction progresses into disease.
You have completed trainings that gave you more information, but still left you unsure what to do first with a real patient.
You want to integrate nutrition, testing, lifestyle, and targeted interventions into a plan that is thoughtful, sequenced, and personalized.
You want to help patients become active participants in their own care.
You want to practice at the root while maintaining evidence, ethics, professional integrity, and still respect the essential role of conventional medicine.

YOU ARE NOT ALONE.

Practitioners across the country—and across health professions—are recognizing the same gap. They want a more thoughtful, evidence-informed way to understand health, involve patients in their care, and practice at the root.

If this sounds like you, you are part of a growing community ready to raise the standard.

The Truth Is...

You chose this work because you care deeply, think critically, and believe every patient deserves to be heard, understood, and included in their own care.
You listen deeply, respectfully, and fully. That is more than bedside manner—it is clinical skill, and it changes what you are able to recognize.
You understand that health is shaped by interconnected systems—not isolated symptoms—and that physiology, nutrition, genetic susceptibility, environment, lifestyle, and lived experience all matter.
Your professional training gave you a valuable foundation, but it may not have given you a clear method for connecting those elements into one coherent clinical picture.
The result is a gap between what you know and the way you want to practice. ROOTED exists to close that gap.

Functional Medicine Needs a Reset

Functional medicine was meant to move healthcare beyond isolated diagnoses and symptom management. It promised a more complete understanding of the individual—their history, biology, environment, lifestyle, and the terrain in which dysfunction developed.

But too often, functional medicine has begun repeating the same disease model it was created to expand.

A conventional diagnosis is replaced with a functional label.
A prescription is replaced with an expensive supplement protocol.
Testing identifies more abnormalities, more recommendations are added, and the patient is sent away to manage an overwhelming plan without consistent follow-up. Once again, the patient is left to heal alone.

THAT'S A BIG PROBLEM.

The tools changed. The thinking didn’t.

Changing the diagnosis from IBS to SIBO, mold illness, dysbiosis, or adrenal dysfunction does not automatically make care personalized. Neither does ordering more testing or recommending more supplements. When every person with the same label receives essentially the same protocol, you are still practicing diagnosis-to-treatment medicine.

ROOTED Resets the Functional Medicine Standard.

ROOTED teaches practitioners a better way to practice Functional Medicine:

Pillar 1:

Understand the Whole Person

Consider symptoms, history, physiology, genetics, environment, nutrition, lifestyle, resources, and readiness before selecting the plan.

Pillar 2:

Connect Systems and Patterns

Connect and interpret information across the body to understand how symptoms, labs, and diagnoses relate.

Pillar 3:

Use Testing With Purpose

Choose testing to answer meaningful clinical questions and influence the direction of care.

Pillar 4:

Sequence and Personalize Care

Prioritize what matters most, choose targeted interventions thoughtfully, and adapt as the patient responds.

Pillar 5:

Use Nutrition and Lifestyle Therapeutically

Apply food, movement, sleep, stress physiology, relationships, and environment intentionally and sustainably.

Pillar 6:

Practice in Partnership

Make the patient an active participant and work alongside physicians, specialists, and conventional medicine when appropriate.

The question should not be:

“What protocol matches this diagnosis?”

instead, it should be:

“Why is this happening in this person, what matters most right now, and what do they need next?”

That is the clinical reasoning ROOTED was created to teach—and the standard functional medicine must rise to meet.

What If You Had a Clearer Way to Practice?

Rooted Provides a Complete Framework for Practicing Functional Medicine.

ROOTED is a 30-week certification that brings physiology, functional testing, systems-based reasoning, therapeutic nutrition, and real-world application into one structured curriculum.

The program replaces guesswork with a clear framework for understanding the whole person, identifying what matters most, and determining what should happen next.

ROOTED builds on your existing professional education and strengthens your ability to connect symptoms, history, labs, nutrition, lifestyle, genetic susceptibility, and environment into one coherent clinical picture.

You gain practical systems for interpreting information, prioritizing decisions, sequencing care, and adapting the plan as the patient responds—so functional medicine becomes thoughtful, personalized, and sustainable in day-to-day practice.

Whether you are just beginning your functional medicine journey or r seeking to refine previous education, ROOTED offers a pathway toward clinical authority and sustainable practice.

Where Training Meets Real-World Practice

Most functional medicine certifications fall into one of two camps:

On one end are short courses—some promising certification after only a few hours, without sufficient prerequisite training or clinical context. They cannot reasonably prepare practitioners for safe, effective, real-world care.

On the other end are long, rigorous certifications packed with theory and research, but often leaving practitioners unsure how to apply what they learned in day-to-day practice.

ROOTED was developed by Kerri Rachelle, a Doctor of Integrative & Natural Medicine candidate, Registered Dietitian Nutritionist, and clinical educator who has walked this same path—navigating the research, investing in advanced training, and recognizing that many programs stop short of what practitioners truly need in practice.

That's why ROOTED was created: to close the gap.

Built inside an active functional medicine practice, ROOTED balances rigor with application. You will master the science while gaining the systems, tools, and clinical frameworks needed to connect the dots and translate your education into thoughtful, individualized patient care.

Choose the Level of Support That Fits You

ROOTED stands on its own as a complete 30-week certification with the curriculum, frameworks, and implementation resources needed to move through the program independently.

Practitioners who want live guidance and case-based learning may add the optional mentorship experience, including weekly group support and access to Root Cause Rounds Case Studies.

Eligible Registered Dietitians may also apply separately for the associated CPEUs or the Registered Dietitian Functional Medicine Fellowship—a selective, hands-on pathway that integrates real clinical experience with ongoing mentorship and advanced case application.

What You’ll Learn in Rooted

Your 30-Week Curriculum

Phase 1:

Functional Medicine Foundations

Establish a strong foundation in functional medicine by learning to think through systems, not symptoms. You’ll explore how the conventional model compares to root-cause, terrain-based care, and why chronic disease demands a different framework. Learn to identify patterns through clinical timelines, connect lifestyle and environmental inputs to disease expression, and understand how antecedents, triggers, and mediators shape health outcomes. This phase also equips you with tools for sustainable practice—confidence, boundaries, and clarity around your role as a practitioner—and introduces the core mindset shifts that will guide everything that follows.

Gut Health & The Microbiome

Build clinical mastery in gut health by understanding the physiology of digestion, the role of the microbiome, and the integrity of the intestinal barrier. You’ll explore the 5R Gut Healing Framework, the hierarchy of digestive dysfunction, and how to prioritize foundational strategies before turning to supplements. We dive deep into the functional approach to GERD, IBS, IBD, Celiac Disease, Non-Celiac Gluten Sensitivity, SIBO, H. pylori, and histamine-driven issues like MCAS. You’ll also learn how to implement and personalize therapeutic diets including AIP, low FODMAP, SCD, paleo, and low-histamine for complex digestive cases.

Phase 2:

The Exposome – Environmental & Lifestyle

Understand how the exposome—the sum of all environmental and lifestyle exposures—shapes immune function, hormonal health, and chronic disease risk. You’ll examine the role of toxins in metabolic dysfunction, mitochondrial stress, endocrine disruption, and immune dysregulation. Learn how to identify hidden sources of toxic burden, from mold and mycotoxins to plastics, pesticides, and water-damaged buildings. We explore foundational detoxification pathways including liver biotransformation, lymphatic flow, bile excretion, and circadian regulation, while emphasizing resilience-building through personalized lifestyle detox strategies.

Organ Function & Detoxification Systems

Discover how the body’s vital organs work together to eliminate toxins, regulate immunity, and maintain internal balance. This month explores the kidneys, gallbladder, pancreas, lymphatic system, spleen, lungs, and heart—not just as isolated structures, but as an integrated network supporting detoxification, digestion, circulation, and cellular resilience. You’ll learn how to assess bile flow, pancreatic enzyme function, and lymphatic drainage, as well as how to support secretory IgA, vagus nerve activity, and mitochondrial health. From cellular housekeeping to oxygen exchange, you’ll gain the tools to optimize whole-body detox and terrain repair.

Phase 3:

Blood Chemistry & Functional Testing

Master the art of interpreting blood chemistry through a functional lens. This month trains you to see beyond standard ranges and uncover early patterns of dysfunction across metabolic, endocrine, and immune systems. You’ll learn how to analyze insulin resistance, lipid markers, and advanced thyroid panels, as well as assess anemia types, methylation function, and nutrient deficiencies. We’ll cover kidney function, electrolyte and acid-base balance, and introduce high-impact markers like vitamin D, magnesium, zinc, and copper. You'll also explore hidden infection, heavy metal load, and immune patterns—building confidence in integrating labs with symptoms and terrain.

Immune & Inflammatory Conditions

Build mastery in recognizing the root causes of immune dysfunction, chronic inflammation, and systemic autoimmunity. You’ll learn how to identify patterns of hidden immune stress. We cover advanced topics like histamine intolerance, MCAS, the gut-immune axis, and the role of gluten across neurological, hormonal, dermatological, and pain-related disorders. You'll also explore complex autoimmune conditions such as Hashimoto’s, Lupus, RA, MS, and Long COVID, while learning how to assess triggers like mold, viruses, heavy metals, and Lyme. This month brings clinical clarity to one of the most misunderstood areas in medicine — and equips you to personalize immune modulation strategies with confidence.

Phase 4:

Chronic Disease Management

Move beyond outdated standards of care and into the root-cause drivers of chronic illness. This module reframes the way we think about cardiometabolic disease by integrating functional patterns in blood pressure, lipid metabolism, insulin resistance, and inflammation. You’ll learn how to interpret anemia in the context of chronic disease, apply advanced markers for cardiovascular risk, and understand how hormone imbalance drives metabolic dysfunction. We’ll explore chronic infection, immune activation, and the deeper terrain issues conventional care often overlooks. This is where your clinical insight and nutritional training become the foundation for truly transformative care.

Thyroid Health

Master the full spectrum of thyroid dysfunction with a functional medicine lens. This module dives deep into hypothyroidism, hyperthyroidism, and Hashimoto’s thyroiditis — exploring how to identify root causes, assess immune triggers, and personalize nutrition strategies for optimal thyroid function. You’ll learn how to interpret complete thyroid panels, address subclinical and cellular hypothyroidism, and understand the nuances of reverse T3 and hormone resistance. We also cover fertility, pregnancy, and postpartum thyroid shifts, as well as nodules, cancer risk, and how to support long-term thyroid health through targeted nutrition and terrain support.

Phase 5:

Hormone Health & Endocrine Patterns

Gain mastery over the interconnected web of hormones that regulate metabolism, mood, energy, reproduction, and resilience. This month explores the full endocrine system through a functional lens — from cortisol, insulin, and thyroid function to sex hormones, adrenal health, and growth factors. You’ll learn how to assess hormonal imbalances across the lifespan, including menopause, PCOS, and andropause, while understanding the root causes of dysfunction such as HPA axis disruption, liver burden, gut imbalances, and metabolic stress. We also examine the impact of overtraining, under-fueling, and fasting on hormone signaling, with clear frameworks for restoring balance.

HPA Axis Dysfunction & Stress Physiology

Explore the complex physiology of the HPA axis and how chronic stress drives dysfunction across every major system in the body. This month unpacks the progression from adaptive stress responses to burnout, fatigue, and chronic disease states — with emphasis on circadian disruption, neurotransmitter imbalances, blood sugar dysregulation, and mitochondrial depletion. You'll gain clinical tools to identify HPA patterns, interpret advanced diagnostics, and address the root causes of stress-related illness. Key connections to thyroid, gut, metabolic, and cardiovascular health are woven throughout, alongside integrative strategies for restoring balance, resilience, and recovery.

Phase 6:

Brain Health, Mood & Cognitive Function

Dive deep into the functional medicine approach to brain health, exploring the root causes of cognitive decline, mood disorders, and neurological dysfunction. This month examines the gut-brain axis, neuroinflammation, and the impact of hormones, toxins, and stress on the central nervous system. You'll learn how to support neurotransmitter balance, protect the brain from environmental insults, and harness the power of nutrition, movement, and circadian rhythm for long-term cognitive resilience. From depression and anxiety to concussion recovery and neurodegeneration, we integrate therapeutic strategies that nourish both brain and body.

Amino Acid Therapy & Clinical Application

This final phase unlocks the power of amino acids as therapeutic tools in functional medicine. You’ll learn how to assess patterns of deficiency, personalize protocols, and use amino acids to target neurotransmitter imbalances, detoxification pathways, gut repair, and immune modulation. From anxiety and insomnia to methylation and tissue healing, amino acid therapy offers a precise, effective way to restore terrain at the cellular level. We close the program by equipping you with a practical framework to confidently integrate amino acid strategies into patient care—and remind you that this is only the beginning of your REV0lution.

A Special Note to Registered Dietitians

Registered Dietitians Belong at the Center of Root-Cause Care

ROOTED is designed for health practitioners across disciplines. It was also created from a deep belief that Registered Dietitians are uniquely positioned to help lead the future of evidence-informed root-cause care.

Dietitians bring extensive education in nutritional biochemistry, medical nutrition therapy, clinical assessment, behavior change, counseling, and the ongoing work of helping patients implement change. That expertise is essential to understanding how physiology, nutrition, environment, lifestyle, and lived experience intersect.

Yet too often, the dietitian’s role is narrowed to meal plans, general education, or recommendations made after the larger clinical decisions have already occurred.

ROOTED helps Registered Dietitians connect the depth of their existing training with functional testing, systems-based reasoning, clinical sequencing, and personalized root-cause care—so they can step more fully into the role they are qualified to hold.

At the same time, ROOTED brings practitioners from across healthcare into a shared framework. Every discipline contributes a different perspective, and patients benefit when those strengths work together.

MEET your educator

Kerri Rachelle

Hi, I’m Kerri Rachelle, PhD[c], RDN, CSSD, FMP-AC — a Doctor of Integrative & Natural Medicine candidate, Registered Dietitian Nutritionist, clinical educator, founder and CEO of REV0lution, and creator of ROOTED.

I know what it is like to continue investing in education while still carrying one unanswered question:

How do I use everything I know with the individual sitting in front of me?

Over the years, I invested tens of thousands of dollars in advanced trainings, certifications, research, and webinars. Each experience expanded my knowledge, but I still had to build the clinical reasoning required to connect that information, determine what mattered most, and translate it into thoughtful care.

ROOTED is the program I wish had existed when I began.

It is the culmination of nearly two decades in clinical practice and education—bringing physiology, nutrition, functional testing, systems-based reasoning, clinical sequencing, and real-world application together within one cohesive framework.

My background as a Registered Dietitian gives ROOTED a distinctly nutrition-first foundation. Nutrition, behavior change, patient communication, and long-term implementation are not side topics here. They are essential parts of understanding the person behind the symptoms.

That depth benefits practitioners across healthcare disciplines. ROOTED was created for thoughtful health professionals who want to practice functional medicine with greater evidence, ethics, clarity, and respect for the individual in front of them.

If you are ready to deepen the way you understand health and raise the standard of root-cause care, I would be honored to welcome you into ROOTED.

Let’s raise the standard together.
