Professional Story

A Passion for Creating Unforgettable Experiences

I believe in the power of personal connection and meaningful relationships. Every event I take on is a balance of creativity, precision, and personal attention. As Simon Sinek says, 'People don't buy what you do; they buy why you do it.' My 'why' is a passion for crafting unforgettable experiences that bring your vision to life.

  • Professional Experience

    With 15 years of international experience in event management I blend creativity with precision in every project. My background in event-focused project management, marketing, and communication shapes exceptional events. Additionally, by teaching college courses at universities in the Netherlands and Germany, I've gained valuable experience in presentation and networking coaching, skills I now use to help clients sharpen their messaging and add clarity and depth to their events.

  • My Clients & Teams

    I work with clients across industries, from tech and healthcare to hospitality, law, and the arts. From C-suite leaders to nonprofits and academic institutions. I collaborate with agencies and project managers, and I lead expert teams to deliver high-level event execution through strong partnerships and clear direction. My philosophy? Great teamwork creates extraordinary results!

Global Experience & Personal Touch

Building Connections Worldwide

I bring a fusion of Dutch directness, global perspective, and Seattle spirit to every event. My international journey enriches each project, creating experiences that transcend borders and bring communities together.

  • Global Journey

    My journey from the Netherlands to the Pacific Northwest shapes how I approach each project, combining European clarity, American adaptability, and a deep appreciation for cultural nuance. Fluent in Dutch and English, conversational in Portuguese, and with basic skills in German, French and Spanish, I bring an international perspective to every project. This background helps me create unique experiences that resonate with diverse audiences.

  • Explorer at Heart

    As a European married to an American and living in the US, I bring a blend of cultural perspectives to everything I do. An explorer at heart, so far I've visited over 25 countries and am on a mission to explore just as many US states! I'm reconnecting with my Portuguese roots and love the outdoors, especially coastal adventures; sunshine and salty air always lift my spirits! I also believe in the power of a great coffee chat. Speaking of which, shall we discuss your next event over Seattle's finest brew?
