About me

After studying business administration, I obtained my federal diploma as a tax expert in Zurich. Since 2010 I have been a partner and director of Fiduciaria Mega, and since 2016 I have been managing the Riva San Vitale office, relocated to Mendrisio in 2022. My professional career began in the shipping industry, where I was responsible for the administrative and accounting management of leading international shipping groups. During my studies in economics, I started working in the business and tax consultancy sector, for a number of fiduciary firms in Lugano, before joining Fiduciaria Mega. Since then, I have been working in the field of national and international tax advisory services for both private and corporate clients. My experience also includes specific tax advice in connection with real estate transactions, business succession and relocation of foreign entities to Switzerland. I sit on the board of directors of operating companies with both local and international activities.
