Meet the Team

Our Staff

Harriet Alvis

She has worked within the Rivers Trust movement for 9 years, first joining West Wales Rivers Trust in 2019. Harriet is also an active member of the Institute of Fisheries Management, including as co-editor for FISH magazine.

Helen Jobson

Senior Executive Officer

Andrew Thomas

Restoration Officer

Having seen a worrying decline in the health of West Wales rivers and wanting to make a difference, Andrew jumped at the chance to join the team as a restoration officer with a focus on working with farmers and landowners.
