About Us
All about SaDeris Group
We built an integrated model where HR, payroll, accounting, tax and migration expertise work together within one trusted team — so you never have to coordinate multiple providers again.
Our Story
Why we founded SaDeris
We founded SaDeris to bring clarity, structure and true coordination to Switzerland's administrative, financial and employment landscape — an environment where precision matters and fragmented advice often creates unnecessary complexity.
Rather than sending clients from one specialist to another, we built an integrated model: HR, payroll, accounting, tax and migration expertise working together within one trusted team. This approach ensures consistency, accuracy and a seamless experience across every step of a client's journey.
Our clients include international professionals, entrepreneurs, self-employed individuals and established SMEs who value discretion, reliability and guidance that spans borders, disciplines and regulatory frameworks.

People shape every workplace and every career. My role is to bring clarity, structure and fairness to these processes.
With extensive experience in HR, payroll and employment regulations across multinational and Swiss environments, I help companies build transparent, compliant practices and support individuals in resolving workplace issues, protecting their rights and growing professionally.
My MBA in Human Resources strengthens my practical expertise and enables me to design solutions that work for both people and organizations.
Strong HR creates workplaces that are fairer, clearer and more sustainable for everyone.
