Sylwia Wyrębek

Office Assistant

Her adventure began at an economic technical school. She later studied for a degree in finance and accounting. She started her career in medical facilities, then in the cosmetics industry, and finally in an office as a secretary.

In her professional career, she carried out customer service trainings, managed documentation and dealt with accounting issues. Until she finally found her way to the iSecure team, where she actively coordinates office and administrative work and supports the Board and colleagues in their daily tasks. Office work has no secrets for her. Not only can she connect a printer and turn Word into a PDF file :)

Her greatest passion is stage improvisation. From time to time she dives into DIY and creates handmade gifts. If sport, it's volleyball. If psychology, it's self-care and working with emotions. She tries to live "here and now".
