Roman Alzengendler: Board Member

Helen Pryor: Board Member

I have worked in community education for 30 years primarily with the Tasmanian Environment Centre and its successor, Sustainable Living Tasmania, my main focus being
climate change. My last project was a Commonwealth Funded Community Action Program called Cool Communities, in which we incentivised people through education, training and financial rebates to adopt more energy-efficient practices in their homes. It was a highly effective program, which saw hundreds of households insulating, draught-proofing,
window-proofing and installing heat pumps, energy-efficient hot water systems and solar panels.

For the past twelve years, my partner and I have run a small business selling second-hand clothes and books. Alongside the business, I have been an advocate for climate-friendly consumerism, presenting at Sustainable Schools conferences and working alongside teachers to implement simple ‘circular-economy’ practices. I am also an active founding member of the Pedestrian and Public Transport Users Group Inc which lobbies Councils and government to improve services and facilities that will discourage car use.

After becoming a university and government sector contracted-staff statistic during COVID 19, she returned to her past career as an Event Coordinator, after realising the important role community events play in community connection, information sharing, a sense of belonging and a community sense of pride. After a 20 year career in event coordination in Cairns, Far North Queensland, Sandra is now focused on raising the community profile of SLT throughout Tasmania, and as she resides in Launceston in the north, she is also hoping that the organization will provide information, pathways and connection that will benefit Tasmania and Tasmanians as a whole.
