This Practice is Especially for You If . . .
- You react to foods, supplements, smells, or environments, and no one has explained why
- You’ve been diagnosed with food allergies, MCAS, Candida, or “idiopathic” symptoms
- Your symptoms span multiple systems — gut, skin, breathing, fatigue, and brain fog
- Antihistamines, steroids, or elimination diets only partially help
- You want a medical doctor who understands both immunology and the microbiome
If this sounds like your experience, you’re not complicated — your immune system needs a more thoughtful evaluation. You deserve answers that connect the dots, not another prescription that masks the symptoms. Complex symptoms require a physician who understands how immune conditions overlap. That’s exactly what this practice was built to address.

Dr. Mitchell Has Been Featured In:
Mast Cell Activation Syndrome (MCAS)
When Everything Triggers Symptoms, Mast Cells May Be the Missing Link.
MCAS can cause multi-system symptoms — including flushing, hives, digestive issues, fatigue, anxiety, and unexplained reactions to foods or environments. Standard tests often miss it, leaving patients frustrated.
Dr. Mitchell specializes in identifying mast cell dysfunction and building structured treatment plans that reduce histamine overload and stabilize immune reactivity over time.
Candida & Microbiome Dysfunction
When Gut Imbalance Drives Immune Symptoms.
Candida overgrowth is often dismissed or misunderstood, yet it can contribute to chronic fatigue, brain fog, digestive distress, skin issues, and immune imbalance.
Dr. Mitchell’s approach focuses on restoring microbiome balance using a structured, evidence-based plan — not extreme diets or endless supplements. His work in this area is detailed in his book Conquering Candida.
Toxic Mold Illness & CIRS
When Mold Exposure Disrupts the Immune and Nervous Systems.
Chronic Inflammatory Response Syndrome (CIRS) can develop after exposure to water-damaged buildings and mold toxins. Symptoms may include fatigue, cognitive changes, sinus issues, heightened sensitivity, and unexplained inflammation.
Dr. Mitchell evaluates mold-related illness through a careful immune and inflammatory lens, helping patients reduce toxic burden and restore immune stability in a safe, medically guided way.
New Patient Experience
“A real doctor can write a prescription but a really good holistic doctor doesn’t need to” – Dr. Dean Mitchell
You May Not Be Our First Stop — But We Intend to Be Your Last.
Many of our patients call Dr. Mitchell the “10th doctor.”
They’ve seen allergists, gastroenterologists, dermatologists, and primary care physicians — yet their symptoms continue.
At Mitchell Medical Group, we take a different approach.
Instead of offering a quick fix, we focus on identifying the underlying immune dysfunction driving your symptoms. Whether it’s food allergies, MCAS, Candida, or mold-related illness, we look at how the pieces connect — not just one isolated issue.
Our 3-Step Approach to Complex Immune Conditions
1. Comprehensive Consultation
Every new patient begins with a detailed virtual or in-person visit. We take time to understand your full health history, symptom patterns, and prior testing — not just the most recent complaint.
2. Targeted Testing & Evaluation
When appropriate, we use advanced diagnostic tools to evaluate immune activity, inflammation, allergies, and microbiome balance. Testing is thoughtful and purposeful — never excessive.
3. Personalized Treatment Plan
You receive a clear, customized plan designed specifically for your condition. Every patient receives a concise written summary, along with Dr. Mitchell’s personal notes, so you leave with clarity and direction.
Our goal is simple:
To help you finally understand what’s happening in your body — and create a realistic, medically guided path forward.

Patient Testimonials
Wonderful practice that integrates their skills as MDs and their knowledge of holistic medicine. Meetings are lengthy because they really want to know how you FEEL! A rarity these days. I no longer live in the metropolitan area, but continue to see them whenever I’m in town in addition to my phone Meetings-highly recommend!
I've been going to Dr. Dean Mitchell for about 4 years now, specifically for allergies and candida treatment, and he has been truly wonderful. I've also been doing allergy drops with him, which I've found to be much more effective than weekly shots, which I did for years, but tended to overload my immune system. There are few doctors who seem to know how to balance traditional medicine with holistic practices. I've found him to be one of the best.
I first came to Dr. Dean last September 2016 with severe Fibromyalgia symptoms. It is almost a year later and I feel fabulous! The quality of my life has now improved by 90%. How do you thank a doctor for giving you your life and health back? I suffered for eight years with this illness, and no M.D. could help me. Dr.Dean Mitchell did and I am so thankful I found Mitchell Medical Group!
I used to suffer from bad (really bad) allergy but immediately after I started Dr. Mitchell’s allergy program, I felt better. I now after 3 years in the program I am 100% better. I never felt this good in my life. I hardly get sick and for a long time I have not used a sick day at work. Thank you, Dr. Mitchell.
Can't say enough about this wonderful practice - Dr. Dean Mitchell and the entire staff are excellent, caring, responsive, professional and of course knowledgeable. Dr. Mitchell makes it his goal to be on the cutting edge of medical innovation and new procedures and medications.
Staff is amazing, friendly, and helpful and most of all Dr. Dean Mitchell is attentive, goes beyond, and sincerely cares for your well being. All the things a Doctor should be and more!
