Yvette Cavender
Headmaster
Yvette Cavender began her partnership with CDA as a parent in 2004, when her children were in grammar school. Soon after, she began teaching second grade and is now the Grammar School Principal at the Flower Mound campus. She has seen the benefits of classical education play out in the lives of her own children and considers it a privilege to collaborate with others in teaching and training students under CDA’s model.

She is currently pursuing her Master of Arts in Leadership for Classical Christian School Administration from Gordon College.

Mrs. Cavender is a strong advocate for classical education. She has presented breakout sessions at classical education conferences such as ACCS, Society for Classical Learning (SCL), and University-Model® Schools International (UMSI). She has spoken about the art of narration on classical education podcasts, participated in seminars regarding school safety, and published articles about creating a classical aesthetic in schools. In support of the classical school movement, she spends time serving on school accreditation teams.
Yvette and her husband live in Carrollton. Their son Chapin is a computational biophysicist at UC-San Diego and their daughter Raegan is currently a stay-at-home mom, but a grammar school teacher by trade.
