For clinicians ready to move beyond symptom management to root-cause care.
A professional pathway to practice functional medicine.
Rooted is a certification program created by a dietitian, designed for dietitians and other licensed health professionals who want to expand their clinical scope. The curriculum integrates functional testing, systems-based reasoning, and therapeutic nutrition into a cohesive framework for practice. Whether you’re beginning your functional medicine journey or seeking to refine previous training, Rooted provides the clarity, structure, and mentorship that allow you to move beyond surface-level care and practice with confidence.
Have You Ever Thought...
You bring the deepest nutrition expertise to the table — yet your role isn’t always recognized as central to patient care.
Your training in clinical science prepared you for complexity — but you’re often expected to follow outdated templates and surface-level advice, without the tools to address root causes.
You want to identify early patterns in labs and symptoms — but conventional care dismisses them as “within range” until disease progresses.
You know nutrition could be applied at the root-cause level — but healthcare systems often limit your ability to do so, restricting both your voice and your impact.
You’re viewed as “the dietary person”— when in reality, you’re capable of building protocols, identifying root causes, and driving meaningful transformation.
You’ve been trained to listen deeply — not interrupt after 12 seconds. That’s not just bedside manner. It’s clinical skill. And it sets you apart as a practitioner.
You're not alone. Dietitians across the country have shared these same frustrations — underutilized, limited by surface-level tools, and searching for a way to practice at the root.
You're ready to rise. Rooted was created to meet that need — offering structure, guidance, and the practical systems that empower you to practice the way you always thought you should.
The Truth Is...
You didn’t become a Registered Dietitian to hand out generic meal plans, supplements and government-issued guidelines.
You chose this field because you care deeply, you think critically, and you believe food has the power to heal.
But conventional training didn’t equip you with the systems to do that. Instead, it confined you to rigid templates and discouraged exploration beyond standardized care.
The result is a gap between the science you mastered and the practice you were prepared for. Rooted exists to close that gap.
What If You Had The Tools?
Rooted Provides a Complete Framework for Practicing Functional Medicine.
This certification integrates clinical depth, functional testing, and mentorship into a structured 12-month curriculum. The program replaces guesswork with a systems-based approach, equipping you with tools you can apply immediately in patient care.
Rooted builds on your foundation in nutrition and clinical science, while adding the functional testing, therapeutic frameworks, and case-based reasoning that conventional training leaves out.
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.
This Certification Is The Missing Framework for Functional Medicine Education
Most functional medicine certifications fall into one of two camps:
On one end, short crash courses — some promising “certification” in as little as eight hours, with no medical background required. These fail miserably at preparing practitioners for safe, effective, real-world care.
On the other end, there are the long, rigorous certifications — packed with theory and research, but often leaving practitioners stranded when it comes to applying what they’ve learned in day-to-day practice.
Rooted was developed by a Registered Dietitian who has walked this same path — navigating research, investing in advanced trainings, and realizing that most programs stop short of what’s truly needed in practice.
That's why Rooted was created: to close the gap. Built inside an active functional medicine practice, this program balances rigor with application. You’ll master the science, but also gain the systems, tools, and mentorship to connect the dots and put functional medicine into action with real patients.
And when you’re ready to go deeper, graduates of Rooted can apply for the Fellowship program — a hands-on experience where you’ll follow cases as they unfold, refine protocols in real time, and strengthen your clinical decision-making with ongoing mentorship.
Pillar 1:
Root-Cause Nutrition That Actually Heals

Pillar 2:
Advanced Lab Interpretation
Develop confidence with both conventional and functional testing. From standard blood chemistry to GI-MAP, DUTCH, and organic acids, you’ll learn how to interpret results with precision and translate them into targeted, root-cause interventions.
Pillar 3:
Clinical Thinking, Not Cookie-Cutter Protocols
Learn to think like a functional medicine clinician. You’ll move beyond symptom management to assess full-body patterns, identify underlying drivers, and build protocols based on real cases — not generic charts or supplement templates.
Pillar 4:
Systems That Simplify Your Practice
Get frameworks you can actually use: protocol sequencing, symptom-tracking models, lab interpretation templates, and communication strategies that streamline sessions and strengthen patient outcomes.
Pillar 5:
Mentorship That Respects Your Credentials
Rooted isn’t a self-study course. You’ll be guided directly by Kerri Rachelle — a clinician who has built and leads a thriving functional medicine practice — and supported by a community of practitioners who are putting these systems into action every day.

What You’ll Learn in Rooted™
Your 12-Month Curriculum
Month 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 month 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.
Month 2:
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.
Month 3:
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.
Month 4:
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.
Month 5:
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.
Month 6:
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.
Month 7:
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. Designed for dietitians ready to lead, this is where your clinical insight and nutritional training become the foundation for truly transformative care.
Month 8:
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.
Month 9:
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.
Month 10:
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.
Month 11:
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.
Month 12:
Amino Acid Therapy & Clinical Application
This final month 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 REVolution.

Here's Why Rooted is Different Than Other Programs...
Most functional medicine trainings miss the mark...
They tend to fall into two extremes: either too surface-level to be useful, or so overwhelming with theory that application feels impossible. Some give you endless research without a single clinical system. Others hand you cookie-cutter protocols and supplement charts, leaving no room for personalization or critical thinking.
Rooted is different — because it was built for dietitians, by a dietitian.
Most programs are created by practitioners who weren’t trained in nutrition the way RDs are — so they skim past the essentials. They might mention macros, therapeutic diets, or patient counseling, but they don’t own them the way we do. Rooted builds on what you already know — metabolism, biochemistry, and medical nutrition therapy — and shows you how to apply it through a functional, systems-based lens. Instead of unlearning your training, you’ll refine it, deepen it, and finally see how it connects to root-cause care.
Other certifications often try to teach nutrition without the accuracy or depth that comes from formal training. The truth? Most physicians receive less than a week of nutrition education — and virtually no training in how to counsel a patient.
As Registered Dietitians, we bring something different.
Six-plus years of rigorous education in nutritional biochemistry and clinical assessment. Training in behavior change and patient counseling that few other providers receive. The ability to listen, integrate, and involve the patient in their own healing. (Contrast that with the average physician, who gets less than a week of nutrition education and interrupts patients within 12 seconds.)
In Rooted, you’ll learn how to think and practice functionally — without the fluff.
You’ll develop mastery in labs, protocol sequencing, and real-world systems that make functional medicine sustainable — not just theoretical. You won’t be left with isolated modules or generic advice. You’ll leave with frameworks, clinical confidence, and mentorship that prepares you to do this work with clarity.
Rooted was designed to honor and elevate the unique skill set that dietitians bring — while giving you the tools and confidence to finally practice at the root.
Rooted Is A Strong Fit For:
Busy practitioners who want mentorship without sacrificing flexibility
Dietitians who know they’re meant for more than meal plans and macros

TESTIMONIALS
Real Clinicians.
Real Change.
I wake up feeling truly fulfilled and connected to my purpose.
I’ve finished the modules and have pages of notes — everything is so well-designed and easy to absorb. This first week has already been incredible. For the first time in my career, I wake up feeling truly fulfilled and connected to my purpose. I’m already seeing new patients and preparing to work with my first Hashimoto’s client next week. I’m just so grateful for this opportunity — and deeply admire Kerri as both a businesswoman and a functional medicine practitioner.

MEET your Mentor
Kerri Rachelle
Hi, I’m Dr. Kerri Rachelle, PhD[c], RDN, CSSD, A-CFMP — a Registered Dietitian Nutritionist, PhD[c] in Integrative Medicine, Certified Specialist in Sports Dietetics, founder of REVolution Health, and creator of Rooted.
But more importantly, I’ve walked the same path you’re on right now.
For years, I invested in every training, sat through countless webinars, and spent tens of thousands of dollars on certifications. What I gained was knowledge — but not the practical systems I needed to apply it the next day with a real patient. I was left with more theory than application, and a deep sense that something was missing.
Rooted is the program I wish had existed when I started. It’s the culmination of over 20 years in clinical practice, designed to combine root-cause thinking, advanced testing, personalized protocols, and the practical systems that actually work in a busy practice.
I believe dietitians — and clinicians who think like dietitians — are among the most qualified professionals to lead in functional medicine. Yet, too often, we’ve been left out of the conversation. That ends here.
If you’re ready to build a practice grounded in science, structured in systems, and aligned with your own voice, I’d be honored to guide you.
Let’s do this, together.
STILL NOT SURE?
