"... in/at Berlin, we... " vielleicht...

Bitte beachten: headquarterS, immer!

Und, wenn auch etwas freier, aber wohl idiomatischer: "From our headquarters at Berlin, we ..."

From our Berlin-based headquarters...

speaking of a more idiomatic translation.... ;-)

From our Berlin headquarters we coordinate the Asian market
or more fluently:
We coordinate the Asian market from our Berlin headquarters.

Alternatives:
headquarters in Berlin
Berlin-based headquarters
headquarters based in Berlin

Just don't omit the final 's' in headquarters.

Hey Alan, beat you by 8 seconds! ;-)

@ badhairday
Curses! Foiled again!

I'm no ardent fighter on grounds of google hit counts, but this finding doesn't seem to be too silent:

"from our headquartes in": 12.900
"from our headquartes at": 344
"from our * headquartes": 12.700
"from our *-based headquartes in": 55

I hasten to add that my suggestion "headquartes _at_" is not quite suitable here, as it would be used mainly with more specifical data on the headquartes' location.
Sorry, if I may have made the impression of telling the natives about idiomatic use, no offense intended.

Oops, please erase 'in' within the last keyword string, it should read "from our *-based headquartes"

Wenn noch eine Alternative zu "headquaters" gesucht wird, hätte ich "hub" anzubieten.

Tausend dank an euch!

spende ein paar Rrrrs für die armen headquartes ;-)

@BBee: yes, you can never get enough arses in HQs, can you? ;)
