Meet the Staff

Hello and welcome to our Staff Page! Here you will find staff bios as well as contact information for each staff member. As principal of STEM, I’m proud to work with such a fine team of individuals who have dedicated themselves to this profession. Our teachers have all chosen to embark on a path that requires a great deal of extra work and dedication to their students. Our staff regularly attends professional development around the state and country and also speaks at conferences regularly about what we are doing at STEM. I’m privileged to be able to serve here and can confidently say that the choice to attend STEM means you/you’re child are in classrooms with the best of the best! Please feel free to reach out to myself or any of our teachers if you have any questions. 

Thank you,
