About me

After completing my degree in Business Administration at the University of St. Gallen, I began my professional career in banking, in the field of wealth management. From 2009 I worked in Zurich as a tax consultant, first at Ernst & Young AG and subsequently at one of Switzerland’s leading tax law firms. In 2013 I obtained the Swiss Certified Tax Expert diploma.

After ten years in Zurich, I returned to Ticino, where I continue to advise private clients, entrepreneurs and companies. Over the years I have specialised in Swiss tax law in international contexts, financial taxation and real estate/property taxation.

In addition to my consulting practice, I teach in the preparation courses for the federal exams for fiduciary experts (TREX) at SUPSI and deliver professional tax courses at the Centro Studi Villa Negroni in Vezia. I am co‑author of the Kommentar zum Schweizerischen Steuerrecht – Bundesgesetz über die Stempelabgaben (StG) and the author of several publications on tax law.
