A complete treatment guide library to
The library holds a complete intervention plan for CBT, DBT, ACT, polyvagal, schema, IFS parts work and every other major modality, each one running from intake to termination. Open any of them and you have the session scripts for every stage, the client worksheets and handouts, the psychoeducation, and the progress notes and clinical documentation. New modalities are added every month. Your practice licence covers all of it: use in session, printing, and giving materials to your clients, for yourself or your whole team.
More clarity. Less searching. Stronger session flow.

Your licence renews at the end of its period for the same price, so your access and your client materials never lapse mid treatment. We email you before every renewal with the date and the amount. Stopping renewal is one click in your account, and your access still runs to the end of the period you paid for.

Who writes these guides
I am Dounia Yasmin, a Developmental Therapist and Educational Specialist. I graduated from Leiden University in 2014 and have worked in child and adult development since, and since 2021 primarily in schools, treatment centres and my own practice.
These guides started as the materials I built for my own caseload. What existed was fragmented. Worksheets without structure, handouts without clinical language, and documentation nowhere at all. So I built the full arc for every subject I worked with, and used it in my own sessions long before anyone else saw it.
What you receive is what I use in my own practice. Never generated, never outsourced.
