Where it all began

1994 – Foundation of NWDA
Established by over 100 members of the Deaf Community in North Wales to address concerns about the changes to Local Authority boundaries and to protect the rights of Deaf People.

1994 – Early Services Initiated
Started with 2 staff members offering information, advice, Deaf Awareness Training, and a quarterly newsletter.

1999 – Expansion of Services
As the organisation grew in size and reputation we were able to employ interpreters, develop lipreading classes, and launched a Child and Family project funded by Children in Need.

2000 – Advocacy Service Established
Following the retirement of many Social Workers for Deaf People, and after talks with the heads of the relevant Social Services Departments, NWDA employed its first Advocacy Officer to continue support services.

Early 2000s – Office Relocation and Growth
Moved to offices in Mochdre, employing 10 people, and developed new services including befriending, video production for all our meetings and an Information Officer who would travel around the region taking the services to people living in rural North Wales.

2010 – Further Expansion
As we continued to grow, we were forced to move again, relocating to the Business Centre in Llandudno Junction, and drew up plans to purchase a permanent building we could grow into. Started an Employment Project and working with Wales Council for Deaf People, began training new lipreading teachers.

2014 – Established the North Wales Sensory Centre
Purchased offices in Colwyn Bay which in turn became the North Wales Sensory Centre, bringing RNIB, Action Hearing Loss, and Guide Dogs under one roof.

2016 – Rebranding to COS
Renamed to Centre of Sign-Sign and Sound (COS) to reflect expanded services, including national projects in partnership with Action on Hearing Loss, and work with individuals with dual sensory loss.

2025 – Consolidated the COS Brand
Updated the brand and communication strategy to reflect the evolving needs of the community we serve.
