Finding an English-speaking doctor in Germany

Even with good German, medical conversations can be hard. Where do you find English-speaking doctors?

Some resources I know:

• doctolib.de — filter by language
• jameda.de — German equivalent with English filter
• Embassy lists (many embassies publish lists of doctors who speak their citizens' language)
• Word of mouth in expat groups
• International clinics in big cities

What about you — how did you find yours? And any specialists worth recommending? (Cities welcome!)
