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.

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.

Dr Mitchell was able to get me past , prior to seeing him, many seasons of allergies colds and asthma . With his help and advice I no longer stress about colds and allergies because I know I am in good hands .
