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.

The Functional Perspective

Podcast

Latest Episode (#245) — October 13, 2026

Millions of people have surgery every year, and the operation is a success. But once the incision heals, almost no one treats the scar, and that can leave lasting pain and restricted movement. Scar tissue specialist Marjorie Brook explains why, and what can still be done, even for scars that are decades old.
