• My name is Krystal Flantroy and I am excited to be a part of the Holt High School Family. This is my nine year of teaching high school science, but I have had wonderful experiences teaching elementary and post-secondary students as well. My true passion lies in making science tangible and relevant to students in their daily lives. In my spare time I enjoy reading, crafting, international travel, and spending time with family and friends. I look forward to working with you and you student(s) this school year!
