Mrs. Grace Twilley

Mrs. Twilley is a proud graduate of Penn State University and the University of Maryland Global Campus. Before entering the world of education, she spent her career in regulatory affairs at UnitedHealth Group. Last year, she served as a Resource Aide at STCS, and she is thrilled to be returning this year as both a Resource Teacher and a 6th and 7th Grade Math Teacher.
​She is currently pursuing a graduate certificate at Penn State in Autism Education and has also begun the Career Switcher program at Regent University to earn a Masters Degree in Education.
As both a St. Theresa parishioner and an STCS parent, Mrs. Twilley feels truly blessed to be part of the St. Theresa community and is excited for the year ahead!
