I grew up in northwest Ohio, the oldest child in a large family.  Having been taught by the Sisters of Notre Dame, I gradually realized that God was calling me to become a Sister of Notre Dame!  It has been my privilege to serve others through the ministry of education at schools in Ohio, Indiana and Florida.  I truly believe that education has the potential to change lives, and it is important to me to stay current in all of the best educational practices.  As the Head of School of Guardian Catholic, I am honored to work with our dedicated faculty and staff as we--together with the parents--help our students succeed in education and in life!
