Our Story
P.L.A.I. was founded in June 2012 when our founder, Dianna Yip, relocated to Hong Kong from Canada and realized that there was a lack of flexible and high quality behaviour intervention services that best fit families’ needs locally. With the belief that every family should receive services that would reduce their stress and improve their quality of life, P.L.A.I. provides individualized home-based intervention that fits every family’s unique needs.
Over the years, we keep expending our services to meet the needs of the communities in the Asia Pacific region. Aside from 1:1 intervention, we also provide school support services, consultations for schools and families, parent and paraprofessional training, supervision for behaviour analysts candidates, and more! We are proud to support our communities with our qualified and passionate team of consultants and therapists. We share the same value and vision – “To support our clients to become valued members of the society through their beauties and strengths”.
"Never doubt that a small group of thoughtful, committed citizens can change the world; indeed, it's the only thing that ever has."
