Testimonials

  • ‘S&S and especially Jérémie Doornaert and Annabelle Bruyndonckx are among the most knowledgeable lawyers in the Life Science sector. They have a very good expertise in regulatory matters for our sector, which is difficult to find. If I don't find the expertise I need with other law firms, I know S&S will have that expertise and be able to help me concretely, always with the aim to achieve the company goals and not just give a useless legal opinion.’

  • ‘Jérémie Doornaert is one of the best expert in Belgium on privacy and data protection and he is also very good on contractual matters, HR and IP. Jérémie has real didactic skills and once he explains something, you understand the whole logic of the law which allows you to build your own expertise and not just get one answer for one specific case. Annabelle Bruyndonckx is the go-to lawyer for anything concerning Life Science. She was the very first lawyer I worked with who gave me 100% satisfaction. She will find what you need and deliver it. ’
