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:

With a 15 year background in information technology and a local green business owner, Julie has a passion for the environment with a major focus on reducing single-use products.  A few years ago, Julie started designing and sewing reusable snack bags for family and friends to reduce plastic waste.  As her interest in sustainable living and zero-waste products increased, Julie grew her passion into a small local business. “Once I learned how to live more sustainably, I wanted to help others live more sustainably”.  Her Eco-friendly business was even featured recently in the Voyage Denver magazine:

Julie has a Bachelor of Science degree from Regis University in Computer Information Systems and she is involved with Sustainable Broomfield as a web designer and IT strategy planner.
