Our  Vision

Meet  Mary Katherine

With almost 25 years of experience in education, the last 17 running an independent school, Mary Katherine Duffy brings a wealth of experience and knowledge of independent school management and leadership. Mary Katherine began her career in business and real estate in 1991, pivoting to education when she was hired as a high school business education teacher in the Harlingen Consolidated ISD. In 2002, she was named the Head of School at St. Alban’s Episcopal Day school in Harlingen, Texas. During her 17 years at St. Alban’s, she gained a tremendous amount of experience in faculty and student retention, enrollment strategy, financial management, and organizational development. Additionally, she was responsible for developing a robust annual giving campaign and an annual signature fundraising event co-led by the church and school and benefiting both entities. In 2014, she spearheaded a capital campaign, in partnership with St. Alban’s Episcopal church, resulting in the renovation and construction of over 3.5 million dollars in facilities.
