Over the last two decades, Wierenga has gained experience in several key roles at ORTEC. After obtaining his Master’s in Mechanical Engineering from Delft University of Technology, he started his ORTEC career in 2002 in the Consulting department. He went on to play a vital role in ORTEC’s expansion into the Central & Eastern Europe (CEE) region: setting up the local operations in the region, co-founding the Bucharest office and taking on the role of Managing Director CEE.

After having spent over a decade in Romania, Wierenga started a new adventure and moved to Atlanta in the United States, an important market for ORTEC globally, to become ORTEC Americas’ Chief Operating Officer. During his four years in the US, Wierenga further strengthened the local team which tripled in size and delivered multiple impactful customer projects.

"“After 15 years abroad, I am excited to return to the Netherlands to contribute to the further growth of ORTEC and to bring value to our customers all over the world.”"

Michael van Duijn, CEO at ORTEC, about the leadership changes: “I am looking forward to work with Herman Wierenga on the next step in our SaaS journey, such as facilitating an easy onboarding, delivering an excellent user-experience and realizing sustainable impact with our customers. Focusing on this has been made possible by Marco Lock, who has transformed this project and our support organization in a professional and efficient operation during his tenure as COO. I am very grateful for everything that Marco has contributed, and I am confident he will enjoy his move to the US in order to prepare our Americas organization for accelerated growth.“
