Stephanie Sierra | ABC7 KGO News Team
I'm a San Francisco native and after 8 years living elsewhere in the country I'm thrilled to be home and part of the ABC7 family! I join the team as an investigative reporter.

My love of journalism started in a classroom at Mercy High School in Burlingame. At the time, 'Career Day' seemed like just a lucky break from the regular school grind of classes and homework. Little did I know it would change my life. I stumbled into a class entitled "A Day in the Life of a TV News Reporter." Intrigued by the idea of highlighting what was going on in the world and prompting change, I was hooked.

I graduated from the University of Missouri where I majored in broadcast journalism. At the local NBC affiliate in Columbia, Missouri I was a reporter and anchor. Yes, I did read the legendary Wayne Freedman book. It's titled "It Takes More Than Good Looks To Succeed In TV News" (Now required curriculum for the J-School!)

While there I earned a national Hearst award for a story that prompted the Sheriff to properly enforce rules that prohibited sex offenders from living too close to schools and day care facilities.

I then spent nearly 4 years braving the snow and high altitude of the Rockies at the ABC affiliate in Colorado Springs (KRDO-TV) as an anchor and investigative reporter. I covered torrential blizzards, grisly murder trials, and exposed scams that prompted action from the Federal Trade Commission.

I did a year-long investigation uncovering the illicit massage industry in southern Colorado, which resulted in six women being rescued from human trafficking operations.

In 2019, I was honored with a regional Edward R. Murrow award after exposing several contractor schemes which resulted in recovering over a hundred thousand dollars back to consumers. Those scams stemmed from a severe hail storm, which our team won a national Murrow award for breaking news coverage. Some of that hail was the size of grapefruits!

I'm thankful there's no hail here in the Bay Area, just breathtaking ocean views, beautiful redwoods, and endless opportunities to tell your stories. I feel incredibly lucky to work alongside journalists I've admired my entire life.

Say hello - I'd love to hear from you!
