The 3 Best Allergists in Portland, OR
Board-certified allergy & asthma specialists practicing in Portland.
If over-the-counter antihistamines stopped working, or your symptoms run for months instead of weeks, a board-certified allergist-immunologist can test what you actually react to and treat the cause. That includes immunotherapy, which lowers your sensitivity over three to five years. Our editors picked the 3 specialists below from the wider Oregon list based on board certification, hospital and academic affiliations, and peer recognition.

That depends on your insurance plan, not your city. Most PPO plans let you book straight with an allergist. HMO plans usually want a referral from your primary care doctor first. Call the practice or your insurer before you book.
How much does an allergist visit cost in Portland?
A first visit with a specialist typically runs $150 to $300 without insurance, and skin testing for a panel of environmental allergens usually adds $200 to $1,000 depending on how many allergens are tested. With insurance you pay your specialist copay, though testing is often billed separately. Ask the office for a cost estimate and their billing codes when you book.
What should I bring to my first allergist appointment?
Bring a list of your symptoms and the dates they flared, every medication you take including over-the-counter ones, your insurance card, and any past test results. Stop antihistamines 5 to 7 days before skin testing, since they can blunt the results. Confirm the exact timing with the office.

Before You Call
Start a symptom log this week. Note the day, what you felt, and what the pollen count was. Two or three weeks of that turns a vague “my allergies are bad” into something an allergist can work from.
