Williams grew up in Morris, Oklahoma, on her parents' farm, where they raised cattle and fresh vegetables.

She moved to Colorado in 1988, and later joined the private sector as a process improvement manager in telecommunications and technology.

She then went on to become an entrepreneur, opening her own business, becoming the principal owner of the Angela Williams Allstate Insurance Agency for 12 years.

As a woman of color serving in the Colorado legislature, promoting legislation that advances equity for all women and the underserved is important to her.

Williams is most known for her biggest accomplishments in the Colorado legislature including successfully passing the ASSET law, which allows undocumented students to attend college with in-state tuition.

She is also proud of the passing of the 2019 FAMLI bill, which will create a family medical leave program after a study and implementation period.

She has also completed the Colorado Foundation for Water Education professional development program and is affiliated with several national organizations.
