Meet Our Team

Brianna Hallinan, President

As Sustainable Broomfield’s President, Brianna not only organizes and facilitates the day to day operations of Sustainable Broomfield, but she also works to establish and maintain strong connections with local community leaders and organizations, to ensure that Sustainable Broomfield is a well-known fixture of advocacy and change within Broomfield. Brianna believes in advocacy through education and community, which is why she has worked to institute Sustainable Broomfield’s latest initiative to provide composting services to Broomfield residents through our Compost Club, while we wait for the implementation of a city-wide curbside, composting service. Brianna also spearheads our efforts to maintain a plot at the Brunner Farmhouse, which allows the opportunity for members to care for a garden space, while also communing with other sustainability advocates. Brianna was recently featured in Voyage Denver Magazine (June 2021) for Sustainable Broomfield:
