Stefan Müller


Stefan Müller specializes in migration and labor law, as well as general corporate law and M&A. His focus is on labor law consultancy, supporting applications for residence and work permits and advising clients on venture capital and private equity financing.

“Despite, or perhaps because of, my belief that the legal profession was monotonous and boring, I decided to study law – luckily! What I appreciate about my job today is the endless variety in my role advising and providing personal support to clients – it’s neither monotonous nor boring.”

Stefan Müller speaks German, English and understands French.

I would like to highlight in particular our work with Stefan Müller. He is our ‘go-to’ partner for the delicate, complex and extremely confidential HR legal requests, where the traditional Company legal partner support is is quite impersonal and standard. Stefan Müller is pragmatic, motivated and very open to debating potential scenarios for solutions. We find his collaboration refreshing and personalised.
