Semblers Assemble!
Meet our awesome team…

Everyone at Semble truly believes in what we do – bringing people together to make positive change. We’re a small and passionate team and like to our community, we’re doers, always looking for solutions and ways to improve the way we work.

Amanda

CEO

Amanda Horton-Mastin

Amanda is responsible for making sure that Semble delivers on its mission of connecting organisations to communities in order to drive positive change. After 20+ years at Comic Relief, she believes passionately in using creativity to drive social  impact and loves working with companies who have purpose. When not running, swimming or playing tennis she can be found cultivating dubious veg in her allotment and making wine in France.

Dominika

HEAD OF CAMPAIGNS

Dominika Jarosz

Dominika is passionate about growing movements that create real change and reconnect people with nature to make life better for people and planet. She can usually be found either cooking up a feast, outdoors in nature or with her head in a book, sometimes all at once.

Andrew

HEAD OF OPERATIONS

Andrew Birley

Andrew loves working with start-ups and small businesses, helping them to get even better at what they do, and how they do it. In his spare time, Andrew is learning bee-keeping and focusing very hard on not being stung.

Dan

SENIOR PROJECT MANAGER

Dan Wooley

Dan believes in the power of the local, and that from small acorns grow mighty oaks. Having spent many years developing volunteer-led campaigns and working with community groups, Dan has now found his natural home at Semble. Originally from the Lake District, Dan is happiest when outdoors and active; he is currently encouraging Semble to recruit a border collie onto the campaigns team.

Hugo

Ségolène

SENIOR PROJECT MANAGER

Ségolène Méheust

Ségolène works across our movement-building and community campaigns. Passionate about creating positive change, she has delivered projects with a focus on sustainability and social impact for NGOs, startups and multinationals. She’s happiest by (or in) the sea, on a rowing boat, hiking (mainly towards a pub) and discovering new places.

James B

PROJECT MANAGER

James Baker

James B manages a variety of our client campaigns, but with a particular focus on employee volunteering. He began as an intern and has developed into his current role across 4 years with the company. In his spare time James is an aspiring cook and avidly supports Arsenal Football Club.
