Who am I?


I am a high school science teacher with a love of chemistry and forensics. I graduated high school in Jonesboro, Georgia. I went on to the Georgia Institute of Technology (Georgia Tech) in Atlanta, Georgia, where I graduated with a Bachelor of Science in Chemistry. I worked at the Marcus Autism Center in Atlanta doing clinical behavior therapy for a few years before moving to Arizona to attend Arizona State University to get my Master of Education in Secondary Education. I taught for a few years in Mesa Public Schools where I became IB trained and taught a few different science subjects (biology, physical science, and chemistry). In order to be closer to my family, I decided to move to Alaska where I am now a part of Palmer High School. In my free time, I enjoy reading, cooking, sewing, binge-watching TV shows, and am an avid sci-fi and fantasy fan. I just got married this summer so will be slowly getting used to my new married name (Grenawalt).


What do I teach?


I am the chemistry and forensics teacher! I love chemistry and forensics and have since I was in high school many moons ago. I am so excited to be able to share this with students this year. Additionally, I am the IB Chemistry teacher. I am happy to be returning to science full time. Previously at PHS, I taught IEA (Indian Education Act) and Migrant Education math and science.

My current courses are: Chemistry, Forensics 1 and 2, and IB Chemistry SL.
