During her time as a Ministry Resident at Saint Mark’s, she is thrilled to live as a member of a community dedicated to and resting upon prayer. She considers herself immensely blessed to have been a part of the shared life of Saint Mark’s for the last three years, and is excited for the opportunities of the year ahead.
