Het sensum instituut

What Het sensum instituut does

Het Sensum Instituut is a specialized early-intervention autism treatment center located in Hoofddorp, Netherlands, serving young children primarily aged 2–6. Founded in 2016 by parents Marianne and Sven following the diagnosis of their son Jort, the organization is the second in the Netherlands to operate under the Droomboom Blaricum model, delivering up to 28 hours per week of 1-on-1 therapy per child — a treatment intensity that the organization states is unique in the Dutch market. Its methodology blends Martine Delfos's developmental-relational philosophy with Pivotal Response Treatment (PRT) and ABLLS-R behavioral tracking, supplemented by 'schaduwbehandeling' (shadow treatment) in mainstream settings such as schools and childcare.

The clinical delivery is supported by a purpose-built 750m2 facility co-located with De Klippeholm primary school and a peuterspeelzaal, comprising 12 individual 12m2 treatment rooms and a 1000m2 outdoor playground. A 23-camera system with audio capture, paired with smart security-industry search software, enables continuous behavioral review of every session. All senior practitioners are SKJ-registered, the organization is ISO certified, and all staff hold a VOG (Verklaring Omtrent Gedrag). Diagnostic and referral flows run through partnerships with Het Ambulatorium and Het Leokannerhuis.

The business model is funded entirely through PGB (Persoonsgebonden Budget) allocations routed via municipal youth-care budgets, with Haarlemmermeer as the primary payer and Amsterdam as a secondary market. The addressable market in Haarlemmermeer is approximately 32 children aged 3–10, making the revenue base structurally small and concentrated. The organization is structured as a Dutch BV (besloten vennootschap) and is currently expanding clinical capacity, with active vacancies for 2 behandelaars and 3 trainees.

Revenue model

1. PGB Youth Care Funding: Treatment at Het Sensum Instituut is fully funded through a Personal Budget (Persoonsgebonden Budget, PGB) provided by the municipality via youth care (jeugdzorg). No own contribution or additional costs are charged to parents. This covers 28 hours per week of one-on-one treatment. The center does not work with the Long-term Care Act (WLZ). A formal expert report from a qualified professional (child psychologist, psychiatrist, or orthopedagogue) is required to access PGB funding.

Core offering

Het Sensum Instituut operates a specialized one-on-one treatment center for young children aged 2-6 with autism or suspected autism, delivering up to 28 hours per week of individualized behavioral treatment at its facility in Hoofddorp. The treatment methodology combines Dr. Martine Delfos's atypical development philosophy with Pivotal Response Treatment (PRT), supported by a proprietary video-based behavioral analysis system. Services are funded entirely through Personal Budget (PGB) youth care funding from Dutch municipalities.

Product overview

Het Sensum Instituut is a treatment center for children aged 2-6 with suspected autism or autistic behavior, offering a unique 1-op-1 individual treatment program as an alternative to group-based care. The core service consists of intensive one-on-one behavioral treatment (up to 28 hours per week) delivered at their facility in Hoofddorp, using video-based behavioral observation and analysis as a central methodology. The treatment methodology combines the philosophy of Martine Delfos with principles of Pivotal Response Treatment (PRT). Supporting services include Shadow Treatment for school transitions, parent training (thuistraining and video home training), and workshops for parents and professionals. The center also facilitates follow-up placement mediation to help children transition to educational settings with appropriate shadow support.

Partnerships

Nine partnerships are on record, tiered core and minor.

• Martine DelfoscoreStrategic or Co-development PartnerDr. Martine Delfos is a key intellectual influence on Het Sensum Instituut's treatment philosophy. Her work proposes that autism is not a defect but an atypical development pattern — children with typical development (TO) first focus on the socio-emotional domain before the cognitive domain, while children with autism (ATO) develop in the reverse order. The center integrates her philosophy with PRT methodology, considering it a core differentiator.
• Het Ambulatorium (Leiden)minorOthersThe Ambulatorium in Leiden is one of the diagnostic institutions with which Het Sensum Instituut has good experiences. It serves as a referral and diagnostic partner for children being assessed for autism prior to or during treatment at Sensum.
• Het Leokannerhuis (Amsterdam)minorOthersHet Leokannerhuis in Amsterdam is a diagnostic institution and treatment center with which Het Sensum Instituut has good experiences. The organization also has historical ties: one of the founders first encountered PRT treatment for their child at Leokannerhuis, which subsequently adopted PRT into its own programs after observing the family's results. The founders describe Leokannerhuis as a referral partner.
• Gemeente HaarlemmermeercoreOthersHet Sensum Instituut works primarily with the municipality of Haarlemmermeer. The municipality is the funding authority (PGB provider) and the organization estimates approximately 32 children in the 3–10 age group in Haarlemmermeer may be eligible for treatment.
• Gemeente AmsterdamminorOthersDue to its geographic location near Amsterdam, Het Sensum Instituut also works with the municipality of Amsterdam for PGB funding and referrals.
• Basisschool De KlippeholmminorOthersDe Klippeholm is a primary school that shares the building with Het Sensum Instituut at Skagerrak 296, Hoofddorp. The school and the center share an indoor gym. The co-location provides natural conditions for children to practice newly acquired skills in real social situations.
• Peuterspeelzaal (co-located childcare)minorOthersA toddler playgroup (peuterspeelzaal) is also housed within the same building at Skagerrak 296, sharing facilities with the center. The co-location allows children to practice skills in authentic peer settings.
• Basisschool De Bikube (former)minorOthersThe center's current location at Skagerrak 296 formerly housed primary school De Bikube, which has since closed. The facility transition allowed Het Sensum Instituut to establish its treatment center in the repurposed school building.
• School consortium / Samenwerkingsverband (Passend Onderwijs)minorOthersDuring the search for follow-up placements for children (KDC, OZA, ZOG, special education, or special basic education), Het Sensum Instituut works intensively with the consortium of the municipality where the child resides. Passend Onderwijs consortiums are also involved in facilitating school placements and providing resources for shadow support.

Direct peers

• Droomboom: The original Dutch institution providing exclusively individual (1-on-1) treatment for young children with autism, located in Blaricum.

• Het Leokannerhuis: Amsterdam-based diagnostic and treatment center for children with autism using PRT methodology. A direct referral partner for Het Sensum; one of the founders first encountered PRT treatment here and Leokannerhuis later adopted PRT into its own programs — making it the most directly comparable treatment-methodology peer.
• Het Ambulatorium: Diagnostic and treatment center in Leiden specializing in autism and developmental disorders. Serves as a diagnostic referral partner feeding children into Het Sensum and operates in the same pediatric autism assessment/treatment category.

Regional players

• Enver: Dutch youth care provider active in multiple regions including parts of North Holland, delivering youth (autism) support and treatment. Comparable as a regional player in the same youth autism care space with municipal funding relationships.

Broad incumbents

• 's Heeren Loo: One of the largest Dutch care providers for people with intellectual disabilities and autism, offering a broad portfolio across many regions and care intensities. Comparable as a large incumbent competing for the same municipal autism/youth care budgets that fund Het Sensum.
• Pameijer: Rotterdam-based care organization supporting people with autism and intellectual disabilities across multiple Dutch regions. Comparable as a broad, multi-region Dutch autism/disability care provider competing for similar municipal contracts.
• Cordaan: Large Amsterdam-area care provider offering youth care, disability support, and elderly care. Directly relevant as a same-region (Amsterdam) incumbent competing for municipal jeugdzorg/PGB-funded autism treatment contracts.
• Philadelphia Zorg: Major Dutch care organization supporting people with intellectual disabilities and/or autism across many locations. Comparable as a large, multi-region operator in the same autism/disability care category that competes for the same municipal funding pools.
