Willem Houck


Willem is a bit of a medical chameleon: he’s the founder and operator of a medical devices company, a medical payment reform company and a medical packaging company. In short, a true entrepreneur with a focus on innovation. He’s also extremely competitive. Imagine how he felt when his 8 year-old daughter beat him at tennis. Bouncing back from defeat, he took up tennis lessons. He needed 2 years to match her level. Last, but by no means least, he’s proud of the growth in TNC membership and exciting new programming effectuated under his presidency.

Stefan van Doorne


Stefan is Partner at KPMG LLP working in the Audit practice within Technology, Media and Consumer Markets. He loves playing golf, running and traveling with his family.

Nicolette Huisman


Nicolette is an International Tax Advisor for Private Equity and Hedge Funds. She’s a total neat freak: tidying makes her unbelievably happy.
