Chief Barketing Officer

Foster is the newest member of the Charter School Division team! He first joined us as a short-term employee in 2017 and returned full-time in 2018. Foster is originally from Rice and moved to Minneapolis in 2016, hoping to enjoy his retirement as a city dog. Foster’s role includes security, janitorial services, and emotional support, and although he spends most of his time on the clock snoozing, he’s always at the ready to perform his duties. His past experience as a wannabe cow dog (not an actual cow dog) prepared him well to wrangle stray schools and keep them on the right path. In his free time, he enjoys pets, snacks, chasing squirrels, and dreaming of catching squirrels.
