Stephan Vonk

Born and raised in the Netherlands, Stephan moved with his wife to Leamington, Ontario (Canada), where he has been living and working for 15 years. In his last position, he was Director of Production and oversaw starting up a farm in the Caribbean, consulting and interim greenhouse management.

“After years of growing, building greenhouses, and supporting greenhouse operations, “it was almost natural to step over to Harmoniz and join this agile, diverse, and motivated company, indeed already well known under its previous brand TomaTech for its top-quality products and solid partnerships with greenhouse growers,” commented Vonk. 

In his new role, Stephan will be part of Harmoniz’s heated Glasshouse team with connections in North and East Europe, collaborating closely with the company’s Mexican team.

“This position requires me to be a bridge between R&D and our trials here in North America, selecting and developing varieties uniquely suited for our climate and needs, providing practical growing support and customer service, and deepening and developing long-lasting relationships with Harmoniz’s customers and the total horticulture industry. With a permanent foothold on our continent, I want to extend the trial capacity, expand our service availability, and make Canada and the USA a top-of-mind area,” concludes Vonk.
