My values

  • Collaboration

    I believe the best results are achieved by having different perspectives and opinions on the table, to be able to craft compelling and holistic solutions.

  • Transparency

    Transparent, honest, and clear communication are core to my person. In tough times, I prefer to talk about things instead of avoiding a conflict.

  • Relatedness

    I value relationships a lot, and it's important to me that we can create a meaningful relationship beyond a working transaction.

  • Curiosity

    There's always more to learn, and I'm happy to learn from you and embrace new challenges with a growth mindset.
