“With a background in two legal systems, I am passionate about the law and know how to communicate complex concepts and key differences effectively. I stay active in professional associations across borders to keep on the frontier of developments in my areas of practice. That allows for creativity and grit on a strong foundation when representing clients. I enjoy looking for the edge, the small, favorable detail, that can decide a case.”
