Wilma Robins – Vice Chair


Wilma has been involved with the MPS Society since its founding in 1982.

Gethin died in December 1984 at the age of five and a half, and thereafter Wilma became involved in the work of the organisation, fulfilling the varying supporting administrative roles and becoming a Trustee in 1990. Wilma’s background as a Civil Servant throughout her working life and her experience in devising and implementing policies, especially in the area of HR, has been particularly useful to the Society. Wilma was born and raised in West Wales and Welsh is her first language.
