Later, she earned an MBA from Colorado State University. Jan's career as an engineer spans more than 25 years.

Jan and her family moved to Colorado in 2007 and chose Thornton because of the community, the opportunities for their growing family, and the feeling of coming home. But Jan's family has strong roots in Colorado. Her Great Grandparents settled in Steamboat Springs as ranchers. They were heavily involved in local education as teachers and founded a community college that is still there today. Jan's parents are also educators. Her father chose to become a public-school teacher after a full career as a pilot in the Air Force. Her mother chose to become a public-school teacher once their commitment to the military and its travel requirements ended.

Jan has been married to her supportive husband Dave since 2002 and together they have two teenage children.

As Mayor, Jan's main priorities include maintaining a strong public safety agenda, ensuring our businesses are thriving, planning strategically for future growth, and strengthening opportunities for neighborhood quality. All to ensure that Thornton remains a great place to live, work, and play.
