HI,
sorry for my late reply i lived in Stuttgart for 1 year and i had my blood transfusions at the Praxis für Transfusionsmedizin inKontakt und Standort
Im Karl-Olga-Krankenhaus

There are two lovely doctors there Dr Schabel, she speaks italian, english and of course german and Dr Stefan Kath, lovely doctor and very good in finding veins, he speaks english too.
they are not specialised in Thalassemia but for the blood transfusion are great and you can get you prescription for the iron chelators as well.
if you live in Stuttgart they are the best. Stay away from Dr Blank in Stuttgart as well.
hope this is helpful for you.
