DVUSA. Volunteers gather for mid-year retreat in Kentucky, by Erica Greil. During the last weekend of January, including the Feast Day of St. Thomas Aquinas, the Dominican Volunteers had the opportunity to reflect on their call to service before returning for the second half of their ministry year. Graciously hosted by the Dominican Sisters of Peace at their motherhouse in St. Catharine, Kentucky, 13 volunteers gathered for Midyear Retreat in what has been called the “Kentucky Holy Land.”
