Meet Our Teachers

I’m Mrs. Heather Underwood, the Windermere Coalition Director and High School English teacher. I’ve been teaching high school literature and composition since 2016 and love helping students think deeply and express themselves clearly and creatively. I enjoy exploring the big ideas found in literature and history while connecting them to God’s truth. My goal is to create a supportive, engaging classroom where students grow in confidence and develop strong critical thinking skills.

Hi! I’m Brandi Barnes and I teach science and history at Windermere. I graduated from Oklahoma State University with a bachelor’s degree in Secondary Education with an emphasis in Biological Sciences. I have nine years of teaching experience in both public and homeschool education, teaching Biology, Botany, Physical Science, American History, Oklahoma History, and General Science.

I’m passionate about creating engaging, hands-on learning experiences that develops confidence in each student as they learn new material and develop long-term retention in their subjects.

My name is Brennan Cook, and I am married to Abby! I grew up in Boston, Massachusetts, and then came to OSU for college. I have stayed in Stillwater to serve as the College Minister at Eagle Heights. I enjoy going on walks with my wife, drinking good coffee, reading a good biography, and watching sports. Teaching is a passion of mine because I love seeing students come to love and worship the one who has made us. My prayer for this semester is that the theology we learn in class leads each of us to doxology, the praise and worship of our God.

Hello! My name is Scarlett Cox and I am the Spanish 2 teacher this year. I am originally from Venezuela but have spent all of my adult years living and working primarily in Oklahoma. I enjoy being outside and spending time with family and friends! I have taught Spanish in the public school system for 7 years and am so excited to teach at Windermere!

I’m Katie Lewis and I teach Literature & Composition, Photography, Graphic Design, and Yearbook at Windermere. I earned a B.A. in English from Oklahoma State University and spent more than a decade as a professional photographer before returning to the classroom. I enjoy helping students grow in creativity, confidence, and critical thinking while discovering the joy of learning. My husband, Scott, and I homeschool our four children and enjoy life together in Stillwater.

Hi, I’m Cindy O’Hara. I have been married for 24 years, have 2 sons and have homeschooled for 14 years. Homeschooling has been quite the journey for our family and I am so thankful that I was able to teach my children.

I am very happy to help Windermere this year and continue teaching.

I’m the Art & Art History teacher and Assistant Director at Windermere and a homeschooling mom of three girls. My husband and I have been married for 24 years, and I’ve enjoyed teaching in a variety of settings, including Christian schools, homeschool, and Pre-K through 8th grade art. Our family enjoys traveling and spending time together, and I also love gardening, taking walks, and exploring new places. I’m excited to learn and create with students this year!
