My name is Andrea Hallis (formerly Castleberry if you've been at WMS 1-2 years). I grew up just north of the CO/WY border in Cheyenne and graduated as a proud EHS Thunderbird. Since then I’ve lived in 3 more states and finished two higher education degrees. I have a Bachelors of Science in Elementary Education and a Masters of Science in Special Education. This will be my 14th year of teaching; my 10th year
as a special educator, and my 3rd year teaching at Windsor Middle School.

Colorado, as you know, is an incredible place to live. My husband took advantage of our beautiful state for our August 2018 wedding. We like to spend time with our families, take road trips, visit friends, and hike.

As a Windsor resident - I like riding my bike around the lake and taking our chocolate lab for walks or swimming.

My philosophy in working with any student is summed up in this way - The learning will take place as you take a risk, try your best, and stick with it. I encourage students to think “bigger.”
Bigger meaning any of the following: globally, empathetically, self-knowledge, independence, or final product.
