Ms. Pettee joins the Business Department where she will teach Personal Finance, Entrepreneurship, and Career Connections. Ms. Pettee begins her 6th year of teaching and joins us from Littleton High School.

Ms. Pettee knows that no matter your interests, AHS has a place for everyone and she is excited to add to that!
Outside of the classroom, Ms. Pettee enjoys her “fur babies”--Reilly (a Pomeranian) and Hattie (a tabby cat) and cheering on the Colorado Avalanche. As a fun fact, Ms. Pettee has been rappelling in New Zealand! She joined People to People, a student travel organization, and had the opportunity to travel to New Zealand and Australia.
