Mrs. Katrina Hartsock - Director of Education


Mrs. Hartsock resides in Austin, TX with her husband Sam and four children.  She converted to the Catholic faith in 2002 and immediately became convinced of the necessity of classical, Catholic homeschooling. The strong relationships and depth of character which homeschooling has fostered in her own family has led Mrs. Hartsock to share homeschooling with other Catholic families through the mission of RCA.

During her 7 years at Regina Caeli, Mrs. Hartsock has served as an upper school tutor, Center Coordinator of Education, and Regional Manager of Education.  She now serves as the Assistant Director of Education working from the Austin RCA center, where her children attend.

Prior to homeschooling, Mrs. Hartsock earned her Bachelor of Science in Electrical Engineering from the University of Texas at Austin and worked at Advanced Micro Devices in both Sunnyvale and Austin.  She has served on the Religious Education advisory board at St. Mary Cathedral in Austin where she has been a parishioner for 14 years, and is active in her local homeschool community.  Some of Mrs. Hartsock’s greatest joys are reading C.S. Lewis with her family, her children’s participation in the St. Joseph Latin Mass Choir, and her family’s annual trips to the mountains.

Annalisa Agustin - Director of Advancement

Mrs. Agustin has been homeschooling since 2010. She and her wonderful husband have eight children. Her family has been with Regina Caeli Academy since its inception in Detroit in 2014. She has served RCA as an upper school lead tutor, local administrator, and regional manager of operations before becoming the Director of Advancement in June 2021. Prior to homeschooling, Mrs. Agustin earned a B.S. in Chemical Engineering from the University of Michigan and worked as an environmental consultant for many years and later for a large non-profit organization.
