Attendance Dean

Samantha Kramer

Ms. Kramer 

As an alumnus of Desert Shadows and Horizon as well as a former classroom teacher at Horizon, it is always great to be a part of Husky Nation. After graduating from the University of Indianapolis with a BS in Sports Administration followed by a BA in Secondary Education with a Masters in Curriculum in Instruction from the University of Phoenix, I spent multiple years in both ESL-based immersion classrooms and science classrooms in the Dysart Unified District. From there, I came to Horizon to teach in the science department for 4 years before heading to Fountain Hills Middle School in 2018-2019 as the Dean of Students. I have additional advanced degrees in MS in Educational Leadership and an MS in Biology (with publication in Down Syndrome and Perceived Exertion through exercise research). I am currently also a professor for Paradise Valley Community College in the Life Sciences Division. I still believe, once a Husky, always a Husky.
