Accounts Manager & Photographer

Rebecca McCrocklin

I have been involved with DSCA since the beginning in 2006. Although I have no formal training in education, and my husband and I have no children of our own, God has called me to minister in a variety of ways to the children of others. Through my love of the Lord, I am blessed to see your children in a special way and, with photography, capture their tender hearts and joyous spirits throughout the school to share with you. It is an honor to serve at DSCA.

K3 Preschool

Brookes Dungan

I am thankful to God for all He has done in my life and is still doing in being conformed to the image of Christ. I believe leading by example is important; I love to read the Bible with my students as I teach them who God is. 
I am passionate about teaching the scriptures to children and youth- it makes me happy as I watch my students learn more about God, as they grow into the individuals God created them to be. I have a Child Development Associates and am working towards obtaining my Masters in Christian Education. My hobbies include playing piano, exercise, horseback riding, hiking, volleyball and travel. I have a heart for missional work and for sharing the Gospel to children around the world. I am very thankful for the opportunity to teach at DSCA!

Robin Carson

I was born and raised in southern Ontario, Canada, and moved with my family to Texas in 1995.  I returned to the area to be with family again last year.  I graduated from University in Waxahachie, TX with a Bachelors degree in Counseling/Psychology.  I have worked in Social Work and different ministries, but most of my experience has been caring for children in a preschool environment (around 10 yrs). I do not have children, but enjoy time with my family (including my niece and nephew).  I love to travel, to be in nature, to read, and to spend time with God.  I also love to explore and learn, and hope to share these joys with the children I teach here at DSCA
Faculty Advisor and 2nd Grade

Kris Maguire​

After graduating from California State University at Chico with a degree in Communication Design, I went on to begin my career in advertising as a Graphic Designer and Art Director. Little did I know what the Lord had planned for my future career path. My husband (who happens to be my high school sweet heart) and I decided early in our careers to pursue jobs overseas. We spent 8 years in Munich, Germany and returned back to the beloved state of Texas with 3 children in tow. While overseas, the Lord placed influential people in my path which in turn led me to begin a new career as a homeschool mother.  Fortunately, coloring for a living was right up my alley. I fell in love with Classical Christian Education and as I began to educate my own children, a whole world of learning that I never experienced opened up before me. History came to life, writing became beautiful, and mathematics…well, were still mathematics. My three beautiful and courageous children are now almost grown and venturing out into higher education.  I love teaching children, especially in regards history and God’s plan in it. It never ceases to amaze and humble me what God has done and is doing.  It is a privilege and honor to be able to share this with little ones.

I am a native Texan, originally from Houston. After graduating from Rice University with degrees in Political Science and Psychology, I worked for a law firm before becoming a full-time mom. Throughout the years, I have taught in various homeschooling and co-op settings, as well as some ESL ministries.

I am excited to be a part of that training at DSCA.
