Kinderpraktijk Op Stap

What Kinderpraktijk Op Stap does

Kinderpraktijk Op Stap is a private pediatric therapy practice founded in 2006 by Kirsten de Zwart and headquartered at Van Hallstraat 81 in Amsterdam, Netherlands, with secondary service coverage in Hilversum. The practice delivers multidisciplinary child development services to children aged 0-18, their parents, caregivers, and schools, spanning occupational therapy (kinderergotherapie), orthopedagogy, diagnostic research, and psychology. Specialty areas include executive functions, kindergarten and writing readiness, sensory information processing, fine motor skills, and self-reliance. The team consists of approximately 8 practitioners plus 1 trainee, including occupational therapists, an orthopedagogue, and a psychologist, all registered in the Kwaliteitsregister Paramedici and trained in sensorische informatieverwerking through the co-owned Kenniscentrum SIEM.

The service portfolio combines individual clinical therapy with seven structured child training programs: KleuterFeest, SchrijfBoost, Beter bij de Les, Expeditie Fijne Motoriek, Cogmed Werkgeheugen Training, Acoustic Pioneer, and Rots en Watertraining. Selected programs use third-party evidence-based software (Cogmed, Acoustic Pioneer, Bascule's Beter bij de Les). The practice also operates the StapDoor sub-brand with Dorien Kikkert (DOOR Ergotherapie), under which two registered educational books ('FIJN!' and 'Fijner schrijven') and online training courses have been published.

The business model is direct-to-consumer with three revenue streams: (1) insurance-reimbursed ergotherapy under Dutch basic health insurance (up to 10 hours per child per year) plus supplementary insurance for additional hours, accessed via Directe Toegankelijkheid Ergotherapie (DTE) without GP referral; (2) out-of-pocket orthopedagogy, psychology, and diagnostic research, which are not covered by basic insurance for children; and (3) unit-priced training programs and book sales, with Rots en Watertraining priced at €350 for 8 sessions and Expeditie Fijne Motoriek at €330.60 for 5 sessions. Services are delivered at the Amsterdam practice, at schools in Amsterdam and Hilversum, and at client homes. The practice reports a 3-6 month waitlist before treatment can begin, indicating demand is at or above clinical capacity.

Scale indicators3 records

Recent moves7 records

Others

• Kenniscentrum SIEM:
• Cogmed (Pearson Clinical): Working memory training program provider; Op Stap is a Cogmed practitioner/reseller in the Netherlands. Comparable as a pediatric cognitive training supplier but upstream rather than competing directly.
• Bascule: Dutch developer of the Beter bij de Les executive function training program that Op Stap delivers to children. Adjacent as a content/curriculum partner rather than a service competitor.

Broad incumbents

• Cortica: US-based pediatric therapy network combining OT, SLP, and ABA for children with autism and developmental delays. Comparable multidisciplinary pediatric model but at vastly larger scale and with insurance-driven US payer mix.
• Centria Healthcare: US pediatric therapy and autism services provider delivering OT, SLP, ABA, and behavioral health to children. Comparable in offering integrated pediatric therapy services though much larger and US-centric.

Direct peers

• Learning Without Tears (formerly Handwriting Without Tears): US publisher of handwriting and fine motor curricula for schools and parents, directly parallel to StapDoor's teacher-focused books and SchrijfBoost online program for writing development.
• KidsAbility Centre for Child Development: Canadian pediatric therapy center delivering OT, PT, and SLP services to children with developmental challenges. Most comparable in mission and service mix, though publicly-funded Canadian model differs from Dutch private practice.
• STAR Institute for Sensory Processing: US specialty center focused on sensory processing disorder assessment and treatment — closely mirrors Op Stap's sensory information processing specialty and SIEM training partnership.
• DOOR Ergotherapie (Dorien Kikkert): Independent Dutch ergotherapy practice led by Dorien Kikkert, who is Op Stap's co-author under StapDoor. Closest direct peer — similar-sized Dutch OT practice with overlapping pediatric specialty and book authorship.
