Functional medicine is a root-cause, whole-person way of practicing: instead of asking only which medication will quiet a symptom, it asks why the symptom is happening and which of your body's systems are involved, then builds an individualized plan around your history and labs. At Pure Body Health, it is delivered by licensed naturopathic physicians, not coaches or non-physician practitioners.
Root-cause work takes time, results vary from person to person, and a licensed physician decides what fits you. Please never stop a prescribed medication without consulting with the prescriber.
▶Physician-reviewed
The best of both worlds: functional medicine by naturopathic doctors.
Functional medicine here is not a menu item; it is how Dr. Sarah Stone, ND (AZ Naturopathic License #15-1496) and Dr. Scott Maymon, ND, MPH (AZ Naturopathic License #15-1497) practice. Both completed doctoral-level naturopathic medical education at the accredited Southwest College of Naturopathic Medicine (now Sonoran University) in Tempe and have cared for patients across Arizona since 2015. As licensed physicians they perform the exam, order and interpret your labs, prescribe when indicated, and recognize when conventional or specialist care is needed.
▶The Approach
Medicine That Asks Why
Conventional medicine is essential for acute problems, emergencies, and active disease, and we use its diagnostics every day. Functional medicine adds a different question. Rather than asking only "what quiets this symptom," it asks "why is this happening, which systems are out of balance, and how do we help the body work the way it should." Both have a place, and we use them together.
For chronic and complex problems, the cause is rarely one isolated thing. Your hormones, metabolism, inflammation, gut, sleep, stress, nutrition, genetics, and environment interact constantly. Someone dealing with fatigue, weight gain, brain fog, anxiety, and poor sleep at the same time may not have five separate diseases; those symptoms often share upstream drivers like thyroid or blood-sugar changes, hormone shifts, nutrient gaps, chronic stress, or gut issues. We look for those connections and build a targeted, measurable plan, rather than adding one more medication for each symptom.
The goal is not more testing or more prescriptions. It is the right testing to answer the right questions, and a plan built on the answers.

▶Sound Familiar?
When You Do Not Feel Well, but Nobody Can Say Why
A lot of our patients arrive after being told everything looks fine, while they still feel far from it. You may recognize some of these:
- Ongoing fatigue that rest does not fix
- "Your labs are normal," but you still feel off
- Weight that will not move no matter what you try
- Brain fog, low mood, or anxiety with no clear cause
- Gut issues: bloating, reflux, irregularity
- Hormone or thyroid symptoms brushed aside
- Bounced between specialists with no plan that connects
- Autoimmune flares or stubborn inflammation
- Poor, non-restorative sleep
- Wanting prevention and answers, not just another prescription
▶What We Help With
Where Functional Medicine Goes to Work
Functional medicine is the foundation that connects our services. Depending on what your evaluation shows, your plan may draw on any of these, and several of them link to a dedicated page where we go deeper.
Hormone Optimization & BHRT
Hormones influence metabolism, mood, bone and heart health, and energy. We evaluate testosterone, estrogen and progesterone, DHEA, cortisol, and thyroid markers to understand the changes of perimenopause, menopause, and low testosterone, and to guide hormone therapy when it fits. Some hormone therapies are FDA-approved; compounded bio-identical hormones are not, and are used under a physician's direction.
Comprehensive Thyroid Health
We look beyond a single TSH, evaluating Free T3, Free T4, Reverse T3, and thyroid antibodies alongside co-factor nutrients (selenium, zinc, iodine) to understand subclinical and autoimmune thyroid patterns, and to support thyroid function.
Metabolic Health & Medical Weight Loss
Weight is driven by neuroendocrine pathways, not just calories. GLP-1 medications (such as semaglutide and tirzepatide) require a consultation and evaluation; we often start with labs (fasting insulin, HbA1c, thyroid, hormones), decide whether they are clinically appropriate for you, and use them inside a monitored plan with muscle-preserving nutrition and physician check-ins. More on medical weight loss.
Gut & Microbiome Health
The gut shapes inflammation, nutrient absorption, and mood. Rather than relying indefinitely on acid suppressors or laxatives, we evaluate microbiome balance, intestinal permeability ("leaky gut"), SIBO, and digestive function to address inflammatory triggers at the source. More on GI health.
Environmental Medicine
Environmental exposures can affect how you feel. When it is warranted, we assess exposures such as mold-related mycotoxins, heavy metals, and other compounds, and support your body's own clearance and liver function, using testing to inform your plan rather than to diagnose on its own. More on environmental medicine.
Chronic Pain & Regenerative
Because systemic inflammation amplifies joint and tissue pain, we pair local options like PRP and peptides with anti-inflammatory and metabolic support rather than relying on long-term NSAIDs or repeated steroid shots. More on our pain care.
Longevity & Healthspan
To support long-term health, we can measure cardiovascular-risk markers (ApoB, Lp(a), homocysteine and others), look at metabolic and cellular health, and use nutrition and IV nutrient support to help you feel and function well over time.
Not Sure Where to Start?
You do not need a diagnosis to book. Start with a physician consultation; we will map your history, decide what testing actually answers your questions, and build the plan from there. Book a consultation. Your physician recommends only what fits your history, exam, and labs. Testing is individualized and informs your plan; it is not a diagnosis on its own. Several therapies are used off-label or are dietary supplements.
▶How It Fits Together
Functional Medicine and Conventional Medicine, Side by Side
These are not rivals. Conventional medicine is essential for acute and emergency care and active disease; functional medicine focuses on the root causes behind chronic, complex symptoms. We use both, and we coordinate with your existing care.
Naturopathic and functional medicine are related but not identical; if you are looking specifically for a naturopathic doctor, see our naturopathic medicine page.
| Where they focus | Conventional medicine | Our functional model |
|---|---|---|
| Primary strength | Acute care, emergencies, surgery, infections, and managing active disease. | Finding and addressing the root causes of chronic, complex symptoms; prevention and long-term vitality. |
| Core question | "What diagnosis fits, and how do we manage it?" | "Which physiological drivers and system imbalances are generating this symptom?" |
| Medications | Often a primary long-term strategy. | Used when indicated, alongside nutrition, hormones, and lifestyle that support the body's own repair. |
| Testing | Disease-screening panels, imaging, pathology. | Conventional labs plus targeted hormone, metabolic, gut, and environmental panels when warranted. |
| Visit style | Brief, high-volume appointments. | Extended intakes that map your timeline, physiology, labs, and environment. |
▶What To Expect
Your Path, in Four Steps
From your first visit to a plan you can actually follow and measure.
01
Step 1. Comprehensive medical evaluation
A detailed 60 to 90 minute physician intake covering your symptom timeline, medical history, nutrition, sleep, stress, environment, and prior test results. This is where the connections start to show up.
02
Step 2. Targeted diagnostic testing
Conventional bloodwork plus select functional panels, chosen for your case. The goal is the right testing to answer real clinical questions, not the longest possible list.
03
Step 3. Your personalized plan
An individualized, multi-phase plan spanning nutrition, hormones, targeted supplements, prescriptions when needed, and lifestyle, coordinated with your existing care team.
04
Step 4. Monitoring and adjustment
Scheduled re-testing and follow-up to measure what is changing and adjust as your body responds. We tell you plainly what is working and what is not.
▶Why Pure Body Health
Physician-Led, and It Shows
"Functional medicine" is a popular term with an uneven bar behind it. Here is what a licensed, physician-led practice adds.
Led by licensed physicians
Elsewhere: "functional medicine" is sometimes offered by coaches or non-physician practitioners. Your exam, labs, prescriptions, and plan are managed by licensed naturopathic physicians who can recognize red-flag pathology and refer when needed.
Root cause, not just numbers
Elsewhere: a prescription for each symptom and a quick goodbye. We look for the shared drivers behind your symptoms and build one connected plan, so you are not managing five problems separately.
Time to be heard
Elsewhere: a brief, high-volume visit that ends before your story does. A 60 to 90 minute first visit that maps your whole history, because complex problems need context.
Honest and coordinated
Elsewhere: endless panels, or "everything is normal, you are fine." The right testing for your questions, straight talk about what the evidence supports, and coordination with your other providers.
▶Next step
Start with a consultation.
Bring your questions. You will get an honest read on whether this is the right fit for you, what a plan looks like, and what it costs, with no obligation to book.
▶FAQ
Frequently Asked Questions
What is functional medicine?
Functional medicine is a root-cause, whole-person approach to care. Instead of asking only which medication will quiet a symptom, it asks why the symptom is happening and which of your body's systems (hormones, metabolism, gut, immune, stress, environment) are involved, then builds an individualized plan around what your history and labs actually show. At Pure Body Health it is delivered by licensed naturopathic physicians, it supports your general wellness, and it can be part of your primary care with us or complement care you receive elsewhere.
Is a functional medicine doctor a real doctor?
At Pure Body Health, yes. Your evaluation and care are led by licensed naturopathic physicians, Dr. Sarah Stone, ND and Dr. Scott Maymon, ND, MPH, who completed doctoral-level naturopathic medical education at the accredited Southwest College of Naturopathic Medicine (now Sonoran University) in Tempe and are Arizona-licensed. This matters because functional medicine is not itself a medical license: the term is used by a wide range of people, including non-physicians. Here, a licensed physician performs the exam, orders and interprets your labs, and manages your plan.
Is functional medicine evidence-based?
Yes. It draws on peer-reviewed research from nutrition, endocrinology, gastroenterology, lifestyle medicine, and systems biology. Therapies are chosen based on published evidence, clinical experience, and your individual presentation, not on a fixed protocol. Where the evidence for a given tool is early or limited, we say so.
Is functional medicine alternative medicine?
Not exactly. It is integrative: our licensed physicians combine conventional laboratory diagnostics and prescription medications when indicated with nutrition, bio-identical hormones, targeted botanicals, and lifestyle medicine. It can work alongside conventional care, not instead of it.
Do I need to stop seeing my primary care doctor or my medications?
No, but we are licensed as primary care physicians in the state of Arizona. Functional medicine works well coordinated with your existing medical team. Please never modify or stop a prescribed medication without talking to the physician who prescribed it.
Are these treatments FDA-approved?
It depends on the tool, and we are straight about it. Conventional lab diagnostics are standard medicine. Some hormone therapies are FDA-approved, while compounded bio-identical hormones and the peptides used for recovery are not FDA-approved and are used off-label under a physician's direction. GLP-1 medications are FDA-approved prescription drugs that we use only when clinically appropriate for you. Environmental and specialty testing informs your plan but is not a diagnosis on its own, and nutrients and botanicals are dietary supplements, not evaluated by the FDA to diagnose, treat, cure, or prevent disease. We cannot claim to cure, and results vary.
What kinds of conditions or symptoms do people come to you with?
People commonly come to us with chronic fatigue, hormone and thyroid concerns, gut and digestive issues, stubborn weight and metabolic changes, brain fog, poor sleep, autoimmune flares, and the feeling that their labs are "normal" but they still do not feel well. We do not claim to cure disease; we work to find and address the underlying drivers, and we refer out when a problem needs conventional or specialist care.
What happens at a first visit, and how long does it take?
Your first visit is a comprehensive physician intake, usually 60 to 90 minutes, mapping your symptom timeline, medical history, nutrition, sleep, stress, environment, and prior test results. From there we order targeted testing based on what your history and exam suggest, then build your plan. It is a genuinely different pace from a brief, high-volume appointment.
Is it covered by insurance, and what does it cost?
Although we do not directly take insurance, some patients choose to submit for reimbursement of services. Some conventional lab work may be billable to insurance while functional and specialty panels often are not. We are transparent about costs before anything is ordered, and we will talk through the plan and the investment at your consultation.
Do you serve Phoenix, Chandler, Gilbert, and the East Valley?
Yes. Pure Body Health is in South Tempe, just off I-10 at Elliot Road on South Priest Drive, and we see functional-medicine patients from across the Valley, including Phoenix, Ahwatukee, Chandler, Gilbert, Mesa, and Scottsdale.
