About this list

The NPI Registry is the U.S. government's public register of clinicians, run by CMS. Where a doctor's own practice or hospital page lists training, languages or focus areas, we add them with a link to that page. Pori does not rank, rate or endorse anyone here and is paid by no one to list them. Call the practice to check it takes new patients and your insurance. Is this your listing? Update it in NPPES and it changes here at our next refresh, or email hello@getpori.app to correct or remove it.

How do I book a dermatologist?

Call the practice: ask whether they take new patients and your insurance, and how long the wait is. Many insurers need a referral from your primary care doctor first. For a quick opinion on a rash or spot, some dermatologists also answer photo consultations online.

When should I see a dermatologist rather than try products?

Book a visit for a mole or spot that changes, bleeds or looks unlike your others, a rash that spreads or hurts, acne that leaves scars or doesn't improve after three months of over-the-counter care, and any sudden hair or nail change. Products are for routine care, not for these.
