Meet Guyleen Castriotta

Guyleen Castriotta was first elected Mayor of the City and County of Broomfield in November 2021 after serving four years on City Council and two years as Mayor Pro Tem. She was re-elected in 2023 in an uncontested race. Mayor Castriotta implemented an ambitious strategy to transform future Broomfield by upgrading long-neglected infrastructure, increasing access to affordable housing, enhancing workforce development, improving government services, and making resiliency and fiscal sustainability a central focus for Broomfield. As Mayor, what guides Guyleen is the belief that the central function of elected officials is to improve the lives of their constituents.
In her eight years serving on Council and as Mayor, Guyleen championed and supported the creation of thousands of new homes across the city at all income levels; worked closely with community to create an expanded public safety strategy with the launch of the co-responder program and key investments in people and businesses for greater stability. Mayor Castriotta has also fought for sustainable city policies and practices that address the climate crisis. Under her leadership, the City Council appointed the very first independent Board of Health and Housing Authority.

Council also adopted a greenhouse gas reduction plan based on emissions inventory to reach 100% renewable energy.
