Gelderse KeepersSchool

What Gelderse KeepersSchool does

Gelderse KeepersSchool (GKS) is a privately held Dutch goalkeeper training school founded in 2001 by Edwin Susebeek in the Achterhoek region of Gelderland, Netherlands. It operates a six-tier structured curriculum — Basis, Basis-plus, Gevorderden, Gevorderden-plus, Topklasse, and Selectiekeepers — covering goalkeepers aged 7 to 35, with each course running twice yearly (spring and autumn) at the SV Westendorp training complex and (for indoor/conditioning work) at a fitness room in Brummen.

The core product is specialized goalkeeper instruction delivered through small-group courses (typically capped at 6–7 keepers per goal and 24–90 participants per course) augmented by Hi-pod video analysis provided to every participant. Adjacent offerings include one-on-one private sessions, duo-training with current professional BVO goalkeepers (Hidde Jurjus, Ties Wieggers), pre-season strength and core conditioning, and B2B services for amateur clubs (on-site demonstration training priced at €350/evening, €525 bundled with a Train de Trainer workshop). Course pricing is publicly disclosed at €210–€350 per person per course and is collected on a pay-as-you-go basis at registration; private and duo sessions are individually priced.

The business is funded entirely through course fees and a roster of roughly 17 local SME sponsors — long-tenured partners include KWD Sport (clothing sponsor since 2001), Altena's Bedrijfs Service BV (head sponsor through 2029), and De Smoks Zelhem (bags through 2028) — with no venture or institutional capital. GKS has produced 112+ goalkeepers who progressed to professional clubs (De Graafschap, PSV, Vitesse, NEC, Telstar, Jong Ajax) and national teams, anchoring its brand and acquisition engine on alumni outcomes rather than technology.
