Scott joined the Outdoor Lab in July 2023 after having served as an assistant principal at Swanson Middle School and Yorktown High School.

Just like our students, Scott is excited to be outdoors, watching students learn and explore in ways that come naturally to children. 

Scott lives in Manassas with his wife (also an APS educator) and has two adult children.
