Chris Harper

Interim Head of School  |  ext. 115

Chris Harper joined our Grace Prep team in August of 2016. Chris’ diverse professional background includes serving as an administrator in both public and privates schools as well as pastoring and planting local churches. Chris holds a Masters Degree from the University of Louisville and is an ordained minister.

Chris’ philosophy of education begins in the home. Chris holds to the biblical principle that dad and mom are the first and foremost teachers, disciple makers, and magistrates in the life of their child(ren). Chris believes that University Model Schools best advance this philosophy as they give time and authority back to parents so that they can “train up their children in the nurture and admonition of the Lord” (Eph 6:4).

Chris is married to Allyson and they have three children; Scarlett, Malachi, and Calvin.

“What I appreciate most about Grace Prep is that it is a place where I can share and live out my faith. And this is important because I’ve learned that children have never been very good at listening to adults, but they have never failed to imitate them.”

Richie Alfred

Athletic Director  |  ext. 103

Coach Alfred is a graduate of The University of Texas at Arlington and has spent 35 years in education. His teams have won over 550 games and made 16 playoff appearances including two trips to the TAPPS Final Four.

Over 50 former players have gone on to compete collegiately. He and his wife Christie have two daughters, Amanda and Ashley.
“Grace Prep is a unique opportunity to coach the game I love and use it as a tool to teach the many valuable life lessons that can be learned through athletics from an eternal perspective.”

Susan Crosier

Principal |  ext. 122

Susan joined the Grace Prep family as the Dean of Academics in June 2016.

Her passion for The Lord and the desire to make a difference in the lives of students makes Grace Prep the perfect place for her. Susan finds that the opportunity to partner with parents in developing college worthy, character witnesses for Christ an honor and blessing. After fourteen years as a classroom teacher in Arlington ISD, she became an Instructional Coach for the district. With many years of experience in education, she came to us with knowledge in a variety of areas and special programs. Susan enjoys building relationships and encouraging students, teachers, staff and parents, while walking alongside them as a thinking partner and advocate for education.

Susan, and her husband Scott, have two children. Emma is a 2016 graduate of Grace Prep and a junior at The University of Mary-Hardin Baylor. Nate is a Grace Prep senior and is headed to Baylor University in the fall.

“What a blessing it is to educate young people while strengthening their spiritual foundation, and relationship with the Lord, in a community of fellow believers. I love the fact that we partner with parents, as they fulfill their roles as primary faith trainers for their children. God continues to bless us with a school family who shares a passion for Christian education. Together, we are creating a generation of college-worthy, character witnesses for Christ. What a Blessing!”

Allison Mauldin

Academic Advisor

Hello Grace Prep Family!

I am so excited to be joining the team as Grace Prep’s School Counselor and College Advisor. Prior to Grace Prep I was a 4th Grade teacher in Grapevine. I attended Grace Prep in Jr. High and High School and went on to attend Dallas Baptist University where I earned my Bachelor of Science in Education. I am married to a Dallas Baptist Graduate, Clayton Mauldin. We live in Flower Mound with our dog and cat. In my free time you can typically find me baking cupcakes or reading (sometimes doing both). Grace Prep has always been a blessing to my life in more ways than academics. It has given my family so much hope and life. I am excited to give back to a school that gave me so much.
