Sandy Flanagan Zull, Seminarian

Sandy’s (she/her) roots are in Southwestern Indiana. Evansville sits along a huge bend of the Ohio River. Her family was more Southern than Northern in speech and culture as most of her ancestors had left farms in Kentucky and Southern Illinois to work in factories. The Ohio River Valley was settled by Germans whose cultural impact remains to this day. All those influences made for an interesting mish-mash of “how we do things.” It never occurred to Sandy that she would ever leave, but leave she did. Sandy attended Indiana State University in Terre Haute and from there her world expanded exponentially. In the decades that followed her life wound through Ann Arbor, Toronto, Pittsburgh, Lancaster, and to her family’s home of twenty-three years, Detroit. They moved here in 1999. Sandy attended Christ Church Detroit from that time until 2008. She married her husband, Aaron, in 1979 when he was the rector of St. John Oak Ridges, Toronto. Single adventures led to a two-some adventuring and then four of us spreading our wings far and wide. They have two grown sons who live in the Detroit area. Sandy had two degrees in elementary education collecting dust as it were. Upon moving here she decided she would drop myself into the Detroit Public Schools at age fifty-five, even thought she had not been in a public school classroom for twenty-five years. Her twelve years in Southwest Detroit combined with specialized work with the Michigan Department of Education have been one of her life’s greatest joys. God’s winds blow us to surprising places. “The lines have fallen for me in pleasant places.” She am delighted to be here, again.
