You take the medications. You attend the follow-ups. Your numbers look “controlled” on paper. And yet you still feel tired, achy, foggy — still not yourself. The diagnosis has a name. The symptoms have a prescription. But nobody is asking why your immune system started attacking your body in the first place.
Across Highland Park, University Park, Preston Hollow, and North Dallas, autoimmune patients are finding their way to us after years of conventional care that managed their condition — but never investigated its root causes. We don’t replace your rheumatologist, endocrinologist, or dermatologist. We work alongside them — adding the layer of root-cause investigation that conventional care doesn’t typically provide. At Modern Functional Medicine Center, that investigation is exactly where we start.
Why Dallas Autoimmune Patients Are Looking Beyond Conventional Care
Dallas has some of the country’s leading rheumatology and endocrinology practices. Patients across North Texas have access to excellent specialists, advanced biologics, and the standard of conventional autoimmune care. So why are so many still searching for more?
Conventional autoimmune treatment is built around a specific goal: suppressing immune activity to reduce symptoms and slow disease progression. For severe disease, that approach can be lifesaving. But it wasn’t designed to ask why the immune system became dysregulated in the first place — and for most patients, that question never gets answered.
Functional medicine starts with that question. Autoimmune disease doesn’t develop randomly — it develops when genetic susceptibility meets specific triggers. Infections. Gut dysfunction. Dietary factors. Environmental exposures. Chronic stress. Identifying those triggers is where meaningful, lasting change becomes possible.
What “Functional,” “Integrative,” and “Holistic” Mean for Autoimmune Care
You’ve probably seen these three terms — functional, integrative, holistic — used interchangeably in autoimmune care. They’re not the same thing. And for a condition as complex as autoimmunity, the differences matter.
Functional medicine asks why. Not what to call the condition — but what’s actually driving the immune dysregulation. Infections, food triggers, gut dysfunction, nutrient deficiencies, environmental exposures — functional medicine systematically identifies the specific factors activating and sustaining your immune response. The Institute for Functional Medicine describes this as a systems-based, root-cause approach.
Integrative medicine combines conventional treatment with evidence-based complementary approaches—nutrition, supplementation, mind-body practices, and lifestyle interventions—used alongside standard medical care.
Holistic medicine treats the whole person rather than the disease label, recognizing that autoimmune conditions are influenced by stress, sleep, relationships, environment, and life circumstances as much as by biology.
At Modern Functional Medicine Center, our team brings all three together. Dr. Andy Martin, MD and Dr. Bronwen Martin, DC, IFMCP — one of fewer than 2,000 practitioners worldwide to hold the Institute for Functional Medicine’s highest certification — offer something rare in autoimmune care: the clinical depth to manage serious medical conditions alongside the functional training to investigate what’s driving them. For autoimmune patients who’ve been told their options are limited, that combination changes what’s possible.
The Autoimmune Conditions We Help Address
Through telehealth, we work with autoimmune patients across Dallas, Plano, Frisco, and McKinney. A diagnosis gives your condition a name — but it rarely explains what caused your immune system to turn on itself, or what’s keeping it there. Hashimoto’s and lupus and rheumatoid arthritis look different on paper. Underneath, the drivers are strikingly similar: a gut barrier that’s been compromised, an immune system stuck in reaction mode, environmental triggers that have never been identified, inflammation that never fully resolves. Find those. Address those. That’s where real change happens.
- Hashimoto’s thyroiditis — the most common autoimmune condition in the United States, and our deepest area of clinical focus. The gut-thyroid-immune connection is central to how we approach it — and it’s where functional medicine has the most to offer patients who are medicated but still symptomatic.
- Graves’ disease and other autoimmune thyroid disorders
- Rheumatoid arthritis — including patients whose joint symptoms persist despite medication
- Lupus (SLE) — flare management, inflammatory burden reduction, and root-cause investigation alongside your rheumatologist
- Psoriasis and psoriatic arthritis — gut dysfunction and immune dysregulation are central drivers of both
- Inflammatory bowel disease — Crohn’s disease and ulcerative colitis, with particular focus on the gut microbiome and intestinal permeability
- Multiple sclerosis — supportive functional care alongside your neurologist
- Sjögren’s syndrome, scleroderma, and other less common autoimmune conditions
The Three-Factor Model of Autoimmune Disease
Most autoimmune patients are never told this — but the science is clear. Autoimmune disease doesn’t develop from a single cause. It develops when three factors converge. Research published through the National Institutes of Health consistently supports a three-factor model of autoimmune disease development.
Genetic predisposition sets the stage. You may carry genes that increase your susceptibility to a specific autoimmune condition. But genes alone don’t cause disease. Millions of people carry autoimmune-associated genes and never develop the condition. Genetics loads the gun. Something else pulls the trigger.
Environmental triggers activate the disease. Chronic stress. Dietary factors. Environmental toxin exposure. Infections your body never fully cleared. These aren’t abstract concepts — they’re specific, identifiable events that flip a switch in genetically susceptible individuals. And unlike your genes, many of them are addressable.
Intestinal permeability—commonly called leaky gut—connects the other two factors. When the gut barrier is compromised, undigested food particles and bacterial fragments cross into the bloodstream. The immune system mounts a response. Over time, through a process called molecular mimicry, it begins attacking the body’s own tissues alongside the perceived threat. This mechanism underlies much of autoimmune disease activity — and it’s almost never discussed in a conventional rheumatology or endocrinology appointment.
Genetics aren’t modifiable. But environmental triggers and gut health are. That’s not a minor detail — it’s the entire foundation of what we do.
How Telehealth Autoimmune Care Works for Dallas Patients
For autoimmune patients dealing with fatigue, joint pain, or unpredictable flares, the practical demands of in-person appointments aren’t just inconvenient — they’re a lot to ask of a body that’s already working hard just to get through the day.
Our telehealth model was built for exactly that reality. You’ll meet with our team through secure, HIPAA-compliant video consultations from home. No driving the Tollway, US 75, or 635. No waiting rooms. No pressure to show up well on a difficult day.
Lab orders go to Dallas-area Quest, LabCorp, and specialty lab locations near you. Food sensitivity panels, comprehensive stool test kits, and mycotoxin testing ship directly to your door for at-home collection. Between visits, you can message our team directly as symptoms or questions come up — no waiting weeks for your next appointment.

The Comprehensive Testing We Use
Most autoimmune patients arrive having had the same standard panel — ANA, basic thyroid, maybe a few inflammatory markers. It rules out the obvious. It rarely explains what’s actually driving the immune dysregulation.
Our diagnostic approach goes where standard testing doesn’t:
- Full thyroid panel including antibodies – TPO, TG, and TSI — for comprehensive autoimmune thyroid evaluation beyond basic TSH
- Comprehensive autoimmune markers beyond standard ANA testing
- Food sensitivity testing to identify dietary immune triggers
- Comprehensive stool analysis to evaluate the gut-autoimmune connection
- Infection screening for EBV, HSV, Lyme disease, and other potential triggers when clinically indicated
- Heavy metal and mycotoxin testing when environmental exposure is suspected
- Comprehensive nutrient panels including vitamin D, B12, ferritin, zinc, and selenium
This level of testing doesn’t just confirm a diagnosis — it reveals the specific biological patterns driving your immune dysregulation. That’s what allows us to build a protocol around your case, not a generic autoimmune template.
Frequently Asked Questions
Q: Will I have to stop my current autoimmune medications?
A: No. Medication changes are made only by your prescribing physician—we never adjust prescriptions independently. We work alongside your existing care, addressing the root-cause factors that conventional treatment doesn’t typically target.
Q: Can autoimmune disease be reversed?
A: We use the language of remission and improvement — not reversal or cure. What we consistently see in patients who do the root-cause work: reduced inflammatory markers, lower antibody levels, fewer flares, better energy, and an improved quality of life. Autoimmune disease requires ongoing attention even when well-managed, and we always set realistic expectations from the start. What changes is how you feel — and what’s driving the immune activity underneath.
Q: Do you treat patients across the DFW metroplex?
A: Yes. We serve patients throughout Dallas, Fort Worth, Plano, Frisco, McKinney, and the surrounding North Texas region via telehealth. We also serve patients in 32 states beyond Texas.
Q: How is this different from a Dallas wellness clinic or alternative health practice?
A: The difference is licensure, diagnostic authority, and clinical training. Dr. Andy Martin, MD and Dr. Bronwen Martin, DC, IFMCP — one of fewer than 2,000 practitioners worldwide to hold the Institute for Functional Medicine’s highest certification — are licensed clinicians, not wellness coaches, supplement retailers, or alternative-only providers. That means we can order and interpret advanced diagnostic testing, work with the same objective markers your conventional specialists use, and build protocols grounded in what your labs actually show. We don’t ask you to choose between conventional and functional medicine. We bring both.
