Welcome to Treehouse Practice

Helping Young People Heal from Trauma


Treehouse Practice is a specialised, team-based service for young people aged 0-25 years who have experienced trauma and adversity in their lives, and the adults who support them. We believe that all children and young people need to feel loved, safe, seen and supported in their relationships and that this is the basis of recovery from trauma. We understand the impact of trauma on childhood development and we support other adults in young people’s lives to become more trauma aware too.

Trauma sensitive services

Our services are available from our therapeutic home in Sandycove, Co. Dublin and through outreach across the island of Ireland. Our therapeutic approach to assessment, consultation and intervention involves integrating specialised models. Our team have pursued additional training in therapeutic models known to help support recovery from childhood trauma, including the following: Theraplay, DDP, play therapy, sensory integration, sensory attachment intervention, Video Interactive Guidance (VIG) and child psychotherapy.


Assessments involve integration of attachment-specific measures and trauma specific methodologies to arrive at an individual narrative of the unique impact for the particular young person, and the therapeutic plan that will aid recovery.


For young people for whom multiple previous assessments have occurred and for whom direct assessment would not be appropriate, we offer the Case Formulation Clinic, a collaborative space for adults to reflect on the young person’s strengths and needs and consider therapeutic responses.

We provide training, reflective practice and supervision to those working in the area of childhood trauma, as well as schools and community services.


Aftercare services

For adults who are care experienced, therapeutic services are continued from the ages of 18-25 years. This support include both individual therapeutic support and wrap-around systemic supports for aftercare services

Therapeutic supports to birth parents of children in care

For birth parents of children in care, we provide therapeutic supports that are designed with the family’s strengths and needs in mind. Therapeutic services include supporting reunification plans, ensuring that children and parents have the best quality visits possible and therapy for parents who have experienced trauma in their lives.

Making a referral

Referral queries sent are to and the clinical team meets weekly for case discussion.
All new referrals commence with a planning meeting which 
allows for exploration of the young person’s strengths and 
needs. Recommendations follow this meeting.
If the young person attends for further assessment and/or 
intervention, pricing will be dependent on the number of 
hours required and the clinicians involved.
