About me: I'm a Patch editor covering news in Denver's metro area and Boulder. I've spent the past nine years working for various news outlets across North America, including Chicago Patch, Global News and WBEZ. I've covered high-profile court cases, civil rights abuses, mass shootings, natural disasters and major crimes — but also countless happy news stories about kindness, innovation and resilience. When I'm not writing articles, I can be found hiking, snowboarding, debating politics with my husband and attempting to be a sci-fi and astronomy geek.
