TORONTO, Sept. 14, 2026 /CourierPR/ -- Topicus.com Inc. announced that Robin van Poelje, the company’s CEO, will retire on October 1, 2026, after leading the firm for over 16 years. The board of directors has appointed Ramon Zanders, currently the Group CEO of the Total Specific Solutions Blue operating group within Topicus, as the new CEO.

Zanders will continue to serve as the Group CEO of TSS Blue alongside his new responsibilities. The transition is expected to be seamless, with Zanders maintaining his leadership role within the operating group.
