What John Koomen does

John Koomen Tuinen, legally John Koomen Hoveniers BV, is a Dutch full-service landscaping and garden design firm headquartered in Wognum, Noord-Holland, founded on 1 March 1988 by John Koomen. The company operates across Noord-Holland and selected Zuid-Holland municipalities (Hoorn, Amsterdam, Alkmaar, Haarlem, Leiden, 't Gooi), employing approximately 45-50 specialists as of 2022-2023. Its core offering covers the full project lifecycle: garden consultation and advisory, custom garden design, construction and installation, renovation, and ongoing maintenance for both residential and commercial/semi-public clients. Specialized service lines include green roof and facade greening (dak- en gevelbegroeiing), BIOTOP natural swimming pools and ponds (as an authorized dealer), green facilities management (groenvoorziening), nature professional services via the Natuurpro network, and garden styling. Notable technical work includes multi-biotope green roofs with 75+ species and biologically filtered, chemical-free swimming pools; complement products include smartphone-controlled drip irrigation and robot mowers.

The business operates on a project-based, quote-driven pricing model with multi-year maintenance contracts providing a recurring revenue layer. Go-to-market is direct enterprise and consultative field sales — no intermediaries — via the website, phone, email, in-person consultations at the Wognum showroom, and on-site visits. Marketing relies on a content-rich website (monthly Tuintips, project galleries segmented by garden style), open days, and the founder's chairmanship of Koninklijke VHG for industry visibility. The customer base spans residential homeowners (primary), real estate developers (Scholtens Groep, Woudt Amsterdam, Duynpark), healthcare providers (Martinus, Ronald McDonald Huis), education (Basisschool Tuitjenhorn, NEMO Science Museum), and municipalities. In 2025 the firm joined Koninklijke Ginkel Groep as a subsidiary, with the founder remaining active in operations and VHG leadership through 2027.
