Finally know what's
making you sick.
Scratch tests, spirometry, and immunotherapy protocols that trade "just avoid everything" for a life where you can eat, breathe, and exist without a plan B.

Most allergic conditions are
misread for years.
Precision diagnostics change the equation. Here's what the data says about undiagnosed allergic disease.
Your asthma medication is treating the smoke, not the fire.
Inhaled corticosteroids quiet inflammation. They don't identify whether it's mold in your bathroom, a protein in wheat, or the neighbor's cat that's driving the reaction. Sublingual immunotherapy works differently — it teaches your immune system to stop overreacting at the source.
Allergen-specific immunotherapy reduces asthma medication dependency by 60% in confirmed responders.
A decade of "probably just stress" has a different diagnosis.
Adults who develop food sensitivities after 25 are frequently told their symptoms are anxiety, IBS, or lifestyle-related. Oral food challenges and specific IgE panels can distinguish true IgE-mediated allergy from intolerance — a distinction that changes whether you carry an EpiPen or simply avoid certain ingredients.
Component-resolved diagnostics identify the exact protein responsible, not just the food family.
Eczema is rarely just a skin condition.
The atopic march — eczema progressing to food allergy, then hay fever, then asthma — follows a predictable sequence that early intervention can interrupt. Patch testing and allergen panels in children under 10 identify environmental triggers before the immune system hardens its responses. The younger the intervention, the wider the window.
Proactive testing before age 8 reduces likelihood of developing asthma by 40% in atopic children.
Treatments that change
how you live.
Three years of weekly drops versus thirty more years of daily pills.
SLIT (sublingual immunotherapy) retrains your immune system using micro-doses of the exact allergen driving your symptoms. Unlike antihistamines — which block the reaction after it starts — immunotherapy interrupts the mechanism before the histamine releases. Most patients complete their protocol in 3 years and remain symptom-free for 7–10 years afterward.
One afternoon. A complete picture of every trigger you've been carrying.
Our workup combines skin prick testing across 58 regional and food allergens, spirometry to measure airway obstruction patterns, and specific IgE bloodwork for ambiguous reactions. You leave with a written trigger map, a severity classification, and a treatment recommendation — not a referral to come back in six weeks.
Sixty minutes.
A lifetime of answers.
Most patients have spent years in a diagnostic limbo — reacting to something, unsure what, managing symptoms rather than causes. One structured visit changes that. Here's exactly what happens.
