Tell us the condition. You get a short list of specialists with real experience in it — each checked on their current hospital or university page (and we tell you when a site couldn't be checked) — plus exactly who to call, what to say and what to ask.
Researched with AI, then every doctor, phone number and link is checked one by one before it reaches you. Run by Utku Güneysu in Istanbul — no doctor or hospital pays us.
Choose your report — $149
Same promise in every report: specialists checked on their current hospital or university page, exact next steps, real stories. Each one is built for what matters in that situation.
e.g. PSC, Castleman disease, vascular EDS, sarcoidosis

I'm Utku Güneysu. I build research and learning tools in Istanbul, Türkiye. Free doctor directories match keywords — they don't know which surgeon has done your operation a hundred times, and they don't notice when that surgeon changes hospitals. WhichSpecialist does that legwork for you.
I'm not a doctor, and we never give medical advice — our job is to find the doctors who can. Every report is researched with AI from US sources (hospital pages, published research, public quality data), then each specialist, phone number and link is checked one by one. I read every email you send.

A plain-English PDF built for one person: you. Not a list of 200 names. Here is what the pages look like — taken straight from our sample reports.
What the condition is and how care is usually organized, so the first appointment doesn't feel like a foreign language.
Chosen for published experience and program volume — each checked on their hospital's or university's own page within days of your report (we tell you if a site couldn't be checked). Plus the closest option to home.
Phone numbers, request forms, referral rules, how to send your scans, help for out-of-state patients.
Fill in the brackets and send. Know what to say in the first 30 seconds of the call.
Print it and bring it. Your doctor sees your key facts and your top 3 questions at a glance.
Real experiences from patients and families — the hopeful and the hard — and the questions that matter most, like "How many patients like me do you treat each year?"
Reply to the delivery email with any question about your report. We answer within one business day.
We email you. If you couldn't get an appointment with any specialist on your list, we research new options at no charge.
Tell us within 7 days. We redo the research once at no charge — and if it still doesn't help, you get a full refund.
The condition name and your state are enough. No medical records needed.
Published research, program pages, patient communities — then every specialist, phone number and link is checked again before it reaches you.
A PDF in your inbox within 3 business days of payment. Questions are welcome for 14 days.
No subscription. Includes 14 days of email questions and the day-30 check-in.
Within 24 hours we'll email you to confirm we can cover your situation, with a secure payment link. Your report arrives within 3 business days after payment.
No. We help you find and talk to the right specialists. We don't identify or confirm any condition and we don't recommend treatments — those decisions belong to you and your doctors.
Never. No doctor or hospital pays to be listed, we don't sell placements, and we take no referral fees. We order the short list by documented experience and explain why for each one. You are our only customer.
No. The condition name and your location are enough to start. If a detail matters (for example, age group), we'll ask by email.
We tell you honestly before you pay. If we find only one verified specialist, we list one — we never pad the list. And if the report isn't helpful, we redo it once, then refund.
Doctors move more often than directories update. For every specialist we open the hospital's or university's own page within days of your report and look for signs it's current. If they've moved, we find where. If a site couldn't be checked, the report says so and names the other source we used.
