DEERFIELD VALLEY- Jeremy Kirk, pastor of the West Dover Congregational Church, convenes an open meeting called Voices of Hope on the last Tuesday of each month, now by videoconference. This is no ordinary church-basement interest group; it is a group of groups, each committed to Windham County’s most vulnerable and marginalized people.These folks have not been idle, as overdose statistics expand and services shrink. At their meeting on Tuesday, December 29, members reported some big results, both in public awareness and new opportunities.
