Established in January 2016 when Holly Jones and Katie Knickrehm wanted better options in the area of STEM for their homeschooled children.  Holly stepped down in May 2017 as Co-director since both of her children were enrolled in school.  Holly was pivotal in the success of STEM Classes of the Triad.

STEM Advisory Board

Director:  Katie Knickrehm

Katie spent five years as a high school special education teacher in a public school, and eight years in the corporate world as a pharmaceutical sales representative.   After moving to North Carolina in 2007, Katie and her husband Mark made the decision to homeschool their six children. STEM grew out of an educational need for her children to take quality, hands-on classes that inspire!  She loves spreadsheets, horses, and tries to stay active.
