Nadja Kellenberger
Certified Finance and Accounting Specialist (Federal Diploma)
Trustee Expert Candidate
I have more than 20 years of experience in the fiduciary sector and in providing comprehensive support to SMEs and private clients. My areas of expertise include financial and payroll accounting, VAT, annual financial statements and tax advisory services.
I gained my professional experience in various fiduciary firms in Eastern Switzerland, as well as during several years with a fiduciary firm in the city of Zurich. This has given me a broad understanding of a wide range of industries and client engagements.
As a fiduciary professional, I value a personal, reliable and straightforward approach. My focus is on providing pragmatic solutions and tailored advice that reflects the individual needs of each client.
