Davis, Haley

My name is Haley Davis and I teach Biology and Human Anatomy and Physiology at Sequoyah High School. I currently hold a Bachelor’s of Science degree in Biology Education from Kennesaw State University. I am in the process of completing a Master’s degree in Secondary Science from Kennesaw State University. I will complete the program in May 2018. This is my third year teaching at SHS. I absolutely love kids and enjoy learning and teaching science, so that is when I decided this career was perfect for me. I am originally from Ellijay, Georgia, but I currently reside in Woodstock, Georgia. I recently got married to my sweet husband Thomas and we are in the process of completing our Master’s degrees and house hunting. I look forward to this year with your child, as we will be learning exciting scientific things! You can contact me at

Rosemary Kamau

My name is Rosemary Kamau. I teach Biology and Zoology at Sequoyah High School. I currently hold an MAT in Biology from Kennesaw State University and a BS in Biology and a minor in Chemistry from Georgia State University. This is my second year teaching at SHS. I love science and enjoy helping students discover and pursue their love for science. In Biology, I incorporate hands-on activities and labs to facilitate student curiosity and understanding of life science. In Zoology, my students explore the animal kingdom during lecture, labs, dissections, and research. Every semester they design their own animal behavior lab, conduct the experiment, and present their data and conclusion in our end of the year Animals Behavior Symposium. I am married and my husband, Paul, and our two sons, Noah (6) and Jude (3) live in Kennesaw. You can contact me at

Kevin Lowery

My name is Kevin Lowery and I am teaching physical science, physics, and AP physics at Sequoyah High School. My degree is in physics from Georgia State University with a concentration in education. I believe this uniquely qualifies me to be successful in a physics classroom. Math and physics concepts are crucial for science and engineering career paths. In my courses, students will learn through online laboratory activities, hands-on lab activities, and exercise problems that relate classroom physics to real-world scenarios. It is my hope to inspire students and make them more interested in science. You can contact me at
