As a Partner at Deloitte Switzerland with 20+ years of experience in Swiss and international tax law, I lead the National Tax Office, ensuring high-quality technical expertise and insights for clients navigating Switzerland's dynamic tax landscape. In my role as Learning, Development & Knowledge Leader for Tax & Legal, I focus on fostering continuous growth and innovation within the firm. Additionally, I serve on Deloitte Switzerland's Tax & Legal Executive Board, contributing to strategic decision-making and market eminence initiatives. Beyond Deloitte, I represent the firm in EXPERTsuisse's Direct Tax Group and serve as a substitute judge at the Zurich Tax Appeals Court, further solidifying my commitment to advancing Swiss tax policy and practice. As a recognised tax specialist, I am regularly quoted in prestigious medias such as Neue Zürcher Zeitung (NZZ), Tagesanzeiger, Swiss Television, and the Financial Times. I frequently deliver presentations at national and international tax conferences and universities, and I chair EXPERTsuisse's tax accounting and reporting certificate course. I frequently publish articles on tax topics and have (co-)authored several books on transfer pricing, tax accounting and reporting, and Pillar Two, all of which offer a strong Swiss perspective.
