Zoe Turner, of Shifnal Matters, has been co-opted onto Shifnal Town Council to represent Idsall ward.
Councillor Turner had been working with the town council prior to her new role through the action group, but will now play a more vocal part in representing Shifnal residents.
"After being part of Shifnal Matters for more than two years, I feel I have some understanding of the concerns of local residents, and by joining the council I feel I can help resolve these concerns," she said.
"Shifnal Matters already works closely with Shifnal Town Council in response to Shropshire Council's Local Plan Review and a number of our members sit on the town council's committees regarding planning, improving parking and the town's Neighbourhood Plan.
"My election will only compliment the work I will continue to do for Shifnal Matters and enable me to help the town's residents further.
"I am looking forward to the challenges that lie ahead and what can be achieved for the town in the future."
John Moore, of Shifnal Matters, added: "Shifnal Matters warmly welcomes the appointment of Zoe Turner as a councillor on Shifnal Town Council.
"Her appointed is fully supported by our nine other core trustees.
"We recognise that Shifnal Town Council has to operate within set parameters whereas Shifnal Matters can respond more quickly to emerging community issues, however we are confident that by working together we can achieve more for our town and Zoe’s appointment is a firm step in that direction.”
Formed in November 2018, Shifnal Matters initially established to fight Shropshire Council's proposals for large-scale development in Shifnal under its Local Plan Review. The group pledges to protect the heritage of the area with sustainable development.
