Meet Guyleen Castriotta
Guyleen has been a fierce advocate for health and safety and our underserved communities. By staying true to her beliefs and her constituents, she’s built an impressive track record of progressive advocacy, successful initiatives, and responsible governance.
A trailblazer in many ways, Guyleen was the first openly lesbian candidate elected to the Broomfield City Council and was unanimously appointed to Mayor Pro Tem in 2019. Her public service record is a strong testament to dedicated, thoughtful, and persistent organizing on critical issues.

To help protect our environment for future generations, Guyleen supported the formation of a new citizen-led Advisory Committee on Environmental Stewardship or ACES. Through these efforts, Broomfield launched the Zero Waste Resolution Campaign in 2020 with the goal of achieving 100% waste diversion by 2035. Council also adopted a greenhouse gas reduction plan based on emissions inventory to reach 100% renewable energy.
Serving as Co-Chair for CCAT (Counties and Commissioners Acting Together) Guyleen forged strong regional relationships to ensure Broomfield has a seat at the table on issues of statewide concern including fiscal reform.
