Frequently asked questions

How do I find a good allergist in Wisconsin?

Look for board certification in Allergy & Immunology, hospital or academic affiliations, and an established practice. Every allergist on this list was vetted against those criteria.

Do I need a referral?

It depends on your insurance plan, not the state. Most PPO plans let you book directly; HMO plans usually require a referral from your primary care physician.

What should I bring to my first appointment?

A list of your symptoms and when they occur, your current medications, your insurance card, and any relevant medical records. A symptom diary matched against local pollen counts is especially useful for diagnosing seasonal allergies.

Track Wisconsin pollen before your visit

Allergists can diagnose you faster when you know which days your symptoms flared and what was in the air. MyPollenPal tracks daily tree, grass, and weed pollen levels for cities across Wisconsin.
