After completing his school education (college of further education, with a focus in economics) in 2000, Erwin Seitler gained experience at the firm Schramm Öhler Attorneys-at-Law. After completing his Austrian military service in 2004, he moved to Singer Fössl Attorneys-at-Law.

The scope of his duties include not only the usual office management and clerical work, but also organising (internal) events, as well as the administration and management of I.T. matters – and, as the case may be – the website.
