My background in STEM began as I pursued and earned a Bachelor of Science Degree in Chemical Engineering from the South Dakota School of Mines and Technology. I worked as a Production Management Engineer and Department Manager for Cargill, Inc in vegetable oil and biodiesel processing facilities in Kansas and Missouri. After relocating back to my home state of Colorado, I found the personal change I needed at the STEM School and Academy in Highlands Ranch. I am in my fourth year of teaching middle and high school mathematics. I am encouraged every day to help and lead my female students to pursuing their own future in STEM.

I am excited to be returning to STEM School for a fourth year as a mathematics teacher.  I have loved math since I was a child and enjoy teaching others to love it too through humor and encouragement.

I have one son and husband and the three of us like to travel, go to the drive-in movie theater and hang out at home with our cat.

Kelley Staggs

I live in Arvada with my husband and have four children, three dogs, a cat, a lizard, four bee hives, and my classic Mustang.  Love hiking, biking, gardening, playing pickleball, kayaking, beekeeping, and doing Zumba.  My Bachelor’s Degree is through Metropolitan State College of Denver, Master’s degree through University of Colorado, Earth Science certification through Colorado School of Mines, trained in STEM and Invention Literacy through CU and Mines teacher enhancement,  and am currently taking classes through Adam’s State College for my Gifted and Talented endorsement.

I have had the privilege of teaching sixth grade GT, regular ed, and special education students in math, science, and language arts in Jefferson County for 25 years, including 10 at Belmar and 15 at Van Arsdale Elementary.   Learning and writing about science is a passion; I have published four books with the American Water Works Association and What’s the Matter with Starting 6th Grade? with Dorrance Publishing. I have written and implemented the Outdoor Lab GT Aquatic Biology STEM curriculum for our high potential week and teach 7th graders up there each summer.  I’m excited to join the North Arvada Middle School staff, integrating STEM into the science program, and sponsoring the Girls in STEM club this year.
