When You’ve Seen 9 Doctors . . . You Come to the 10th
Holistic Care for Complex Immune and Inflammatory Conditions
Specialized Medical Care for Complex Immune and Inflammatory Conditions that are Often Overlooked, Misdiagnosed, or Dismissed
Most of our patients don’t come to us first.
They’ve seen allergists, gastroenterologists, dermatologists, neurologists, rheumatologists — sometimes all of them. They’ve been told their labs are normal. That their symptoms are stress. That it’s IBS. That it’s anxiety.
But the symptoms are real. Recurring food reactions. Brain fog. Histamine intolerance. Chronic fatigue. Unexplained inflammation. Mold sensitivity. Persistent Candida. Mast cell flares.
When traditional medicine doesn’t connect the dots, you need a physician who understands immune dysregulation at its root.
Dr. Dean Mitchell is often called the “10th doctor” because he specializes in the complex, overlapping immune conditions that many doctors were never trained to diagnose or treat.
Most of the chronic conditions we treat are the most difficult conditions to diagnose and treat. Ask any physician – most don’t even want to see a patient that thinks they have any of these medical problems because they don’t believe they are real. Well, at Mitchell Medical Group not only do we believe these debilitating medical diseases are real, but we also have some of the best treatment protocols to get our patients better. This is why we like to refer to our treatment as “The Real Deal”.
You’re Not Crazy. Your Immune System Is Overreacting
We specialize in patients who:
React to foods but test “negative”
Have unexplained histamine symptoms
Experience recurring Candida despite treatment
Have mold exposure and ongoing inflammatory symptoms
Are told everything is normal — but feel anything but normal
Feel dismissed, rushed, or unheard in traditional appointments
These are not “mystery illnesses.” They are patterns of immune dysregulation. And they require a physician trained to see the full picture.
Our Clinical Focus: Complex Immune & Inflammatory Disorders
Dr. Mitchell’s practice centers on conditions that frequently overlap and amplify one another. These conditions rarely exist in isolation. They often overlap. That’s why our treatment approach is integrated – not fragmented.
Food Allergies & Complex Food Reactions
True IgE food allergies, delayed immune reactions, histamine intolerance, and food-triggered inflammation.
Mast Cell Activation
Syndrome
Mast Cell Activation Syndrome (MCAS) is often misunderstood and underdiagnosed. Mast cells regulate inflammatory responses throughout the body.
Chronic Inflammatory Response Syndrome (CIRS) / Toxic Mold Illness
Chronic Inflammatory Response Syndrome occurs when mold exposure triggers persistent immune activation.
Candida Overgrowth & Microbiome Imbalance
Dr. Mitchell takes a microbiome-informed approach — not just antifungals, but gut restoration and immune stabilization. He is the author of the book Conquering Candida

What Makes Mitchell Medical Group Different?
Board-Certified Allergist and Immunologist
Dr. Dean Mitchell is not an internet-based “functional” practitioner.
He is conventionally trained and board-certified — with decades of clinical experience.
Time and Attention
Appointments are comprehensive and investigative — not rushed 10-minute visits.
Expertise in Overlooked Conditions
He focuses on areas many physicians were never formally trained to address:
- MCAS
- CIRS
- Histamine disorders
- Chronic Candida
- Complex immune activation
A True Root-Cause Investigation
Rather than suppressing symptoms, he evaluates:
- Immune pathways
- Environmental triggers
- Microbiome health
- Inflammatory markers
- Detoxification capacity
- Food reactivity patterns
Integrated Treatment Strategy
Combines:
- Evidence-based medicine
- Targeted supplements
- Medication when appropriate
- Environmental interventions
- Diet modification
- Immune stabilization protocols
Functional Medicine — Without Abandoning Real Medicine
Many patients fear choosing between “conventional” and “alternative” medicine.
You don’t have to. Dr. Mitchell bridges both worlds.
He uses:
- Advanced diagnostic testing
- Traditional lab evaluation
- Clinical immunology expertise
- Microbiome-informed treatment strategies
- Environmental medicine principles
The goal isn’t to label you. The goal is to stabilize your immune system. When immune dysregulation is addressed correctly, symptoms often begin to calm.
Telehealth New Patient Meeting
You can meet with Dr. Mitchell from anywhere in the country. He personally takes your full medical history — the step he considers most important in understanding a complex case — and you speak with him directly. There is no medical assistant or trainee taking your history and relaying it back to him.
What happens next depends on where you live. If you are in New York State, a virtual visit works the same way an office visit does. If you are outside New York, state licensing rules shape what Dr. Mitchell can provide directly: your consultation is educational, and he will review your history, explain how he thinks about cases like yours, and can speak with your local physician to guide the plan. Many out-of-state patients then travel to our Manhattan or Rockville Centre office for treatment.
These telehealth visits are intended for educational and informational purposes only. My goal is to help provide you with these resources to work with your local healthcare provider to get the best care possible.
Call our office today at 347-916-3571 to schedule your meeting or request an appointment online.
