Clare Hathaway was born in Mid Glamorgan in 1986 and grew up in the Rhondda. She joined Valleys Kids at around 10 or 11, where she became involved in creative activities and youth theatre. These experiences helped her gain confidence, explore opportunities beyond the Rhondda, and eventually study drama at university. After graduating, Clare returned to Valleys Kids, later worked as a creative practitioner abroad and in London, and eventually came back to work professionally with the organisation. Valleys Kids has been a major influence throughout her life, and she remains deeply connected to its work and values.
