If the figures add up and everything is in order, my day is already a success.

As a Finance professional, I make sure financial processes run smoothly. From time registration and accounts payable and receivable to salary payments and the administration of our self-employed professionals. I also answer questions from clients and professionals, and step in wherever needed within the finance department. It’s exactly this variety that makes my work so enjoyable; no two days are the same.

My strength? I’m driven, precise and committed. And to be honest, sometimes a little impatient as well. I like things to be done both correctly and quickly. Keeping oversight, taking action and delivering quality go hand in hand for me.

What can you expect from me? A practical approach, clear communication and someone who enjoys thinking things through with others. I prefer working in an open and positive way, where everyone knows where they stand.

And outside of work? You’ll often find me being active in sport or out exploring. It helps me clear my head and recharge my energy.

You can reach me from Monday to Thursday. Friday is for me.

Yellowstone is snel gegroeid, en daarom ben ik begin 2019 bij het financiële team gekomen. Samen met drie collega’s zorgen we voor een correcte afhandeling van financiële taken, waaronder facturering, registratie en urenregistratie.

Ik controleer ook pensioenverklaringen, verzorg audits, ziekteverlof en klachten.

Ik ben op woensdagen en vrijdagen na 12.00 uur niet beschikbaar.

Sinds september 2021 werk ik bij Yellowstone Contract Management ter ondersteuning van de financiële afdeling. Hier ondersteun ik mijn collega’s Marian, Lisette en Jolanda bij diverse financiële taken, waaronder urenregistratie en facturering.
Daarnaast ben ik verantwoordelijk voor de registratie en afhandeling van margincontracten met verschillende partijen.

Ik ben op maandagen niet beschikbaar.

Behind every timesheet, leave request or sick leave notification is a person. That’s something I never lose sight of.

As a Finance Professional, I make sure everything runs smoothly behind the scenes. I process and review timesheets and take care of the administrative handling of sick leave and leave requests, including maternity and parental leave arrangements.

I like to work in a structured way, with a clear overview and a strong eye for detail. My strength lies in processing information carefully and accurately. That combination of precision and keeping the person behind the data in mind is what makes this work so meaningful to me.

What can you expect from me? Clear and friendly communication, a careful approach and prompt follow-up on questions. I believe it’s important that collaboration feels easy and pleasant, and that everyone knows where they stand.

And outside of work? I enjoy long walks with my partner and our dog, Sam, getting away on holiday whenever I can, and spending time with my grandchildren. Sharing special moments and making memories together is what makes me happiest.

You’ll find me here from Monday to Wednesday and on Fridays. Thursday is for me.

Ik werk sinds augustus 2025 op de financiële afdeling van Yellowstone. Mijn werk bestaat uit het nauwkeurig verwerken van gewerkte uren, zoals urenstaten, en het ondersteunen van diverse financiële en administratieve processen. Ik waardeer vooral de dynamiek van de baan en het contact met mensen van verschillende nationaliteiten die via Yellowstone werken.

Ik ben op maandagen niet beschikbaar.
