Dr. Mitchell Has Been Featured In:
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.

Frequently Featured in National Media
Trusted by major outlets, such as Self, Fox News, Newsday and HuffPost, to explain complex immune and allergy topics clearly and responsibly.
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.

Patient Testimonials
There are absolutely no words that are adequate to thank you for your extraordinary diagnostic skill and for the care and attention that you have lavished on me. As you know, I had seen at least 10 doctors before I was lucky enough to make your acquaintance. I have felt so sick for so long that I had forgotten what it was like not to feel so terribly ill. Whatever you did for me, I believe and hope that the medicine you prescribed is making a difference. I have felt better for the last two days that I have been taking your medication and I am deeply deeply grateful to you. I am stunned that you cared enough to call me last night at 7:00 PM. That is definitely above and beyond the call of duty. I just want you to know what an amazing and wonderful doctor you are and that I will NEVER forget your kindness and expertise. Thank you so very very much.
i’m sure I posted review 13 years ago the first time I saw Dr. Mitchell but it’s definitely time for another one. When I was 31 I was on deaths door. I struggled for a year and a half to figure out what was wrong with me. I saw a ton of dctrs and no one could figure it out. I got to Dr. Mitchell finally and he diagnosed and cured my systemic candida in six weeks. Fast-forward 13 years. I was in a very traumatic car accident May 2025. I started to get body rashes on the left side of my body last September (never thinking it would be candida bc I had been in remission so long). I finally met with Dr. Mitchell at the end of January, and he put me back on a strict Candida protocol. All was going well, but I continued to frequent a hot yoga class. I had taken a six week break during healing the candida and went back and my entire face and neck blew up. I got on a telehealth with Dr. Mitchell. He immediately knew it was mold and mycotoxin poisoning as well as MCAS. He did a real time urine test so he could figure out exactly what mold to target and yesterday I met with him and got the protocol. He assures me. I will be better in three months and I have full trust in him since he saved my life 13 years ago. I have a friend who had the exact same thing and she says it took her four years to get better. Dr. Mitchell is literally a “wizard” lol. At least that’s what me and my mom call him because he is so good at what he does. I have never met a doctor thats so dialed in and knowledgeable regarding looking at the body as an entire system. His office staff Maria and Patty have been with him for 25 years. They are amazing and gracious and always answer my emails. If you have health issues that no western medicine dctrs can diagnose look no further for a doctor because Dr. Mitchell is your man!
Dr. Mitchell was great! Really helped us with our allergy situation. One night of revised protocol and already a vast improvement for my son.
Amazing experience, the team was accommodating and understanding from the first phone call, made everything very easy, answered all questions immediately. Dr Mitchell was on time for my apt which is rare these days, he listened and didn’t cut me off or make me feel crazy while explaining my 30 plus symptoms. He had a clear plan of action for my complex condition that I’ve been suffering from for 3+ Years and his team followed up immediately and gave clear instructions on next steps. Overall best experience I’ve had after seeing over 22 doctors since I got sick.
My visit with Dr Mitchell was excellent. His expertise has helped me tremendously over the past 6 months. I had been struggling for a full year prior with candida overgrowth in conjunction with anaphylactic MCAS symptoms. Prior to Dr Mitchell none of my doctors had answers and a specialist kept telling me I just had a contact dermatitis. I’m looking forward to continuing my health journey with Dr Mitchell’s guidance. His staff is very friendly and extremely professional. I highly recommend the Mitchell Medical Group.
Dr. Mitchell is an amazing doctor that has treated our young, nut-allergic daughter for the last few years with sublingual drops. The treatment has significantly reduced her sensitivity and reactivity and has given us piece of mind knowing that she is so much safer and can lead a normal life without being burdened by her allergy. We would highly recommend Dr. Mitchell to anyone else considering this treatment!
