School Leadership
Meet Our Director

Heidi Velsen
Director, Stephenville Christian Academy
Heidi Velsen was born in Vermont and moved with her family to the Netherlands at the age of four, where she was raised and received her education. Growing up in another country gave her a deep appreciation for different cultures, communities, and approaches to education.
In 1995, Heidi returned to Texas with her husband, Bert, where they began a dairy farming operation and planted roots in the Stephenville community. Together, they built a life centered around faith, family, hard work, and service. They are blessed with one daughter, Esmae, who is one of their greatest joys.
Before becoming Director of Stephenville Christian Academy, Heidi served Stephenville ISD for 15 years. Her years in public education strengthened her love for students, families, teachers, and the school community and reinforced her belief that children thrive when they are known, encouraged, and genuinely cared for.
Heidi considers her role at SCA not simply a career, but a calling. Her desire is to help create a school where academic excellence and spiritual growth go hand in hand and where Jesus Christ remains at the center of everything we do.
She believes education is about more than academics it is about shaping character, building confidence, nurturing faith, and helping children recognize the unique gifts and purpose God has given them.
Heidi and her family are active members of Stephenville Christian Reformed Church, and her relationship with Christ is the foundation of her leadership. She strives to lead with prayer, humility, integrity, compassion, and a servant’s heart.
Her hope is that Stephenville Christian Academy will always be a place where children are known by name, families feel welcomed, teachers feel supported, and Christ is reflected in everything we do.
“Her hope is that Stephenville Christian Academy will always be a place where children are known by name, families feel welcomed, teachers feel supported, and Christ is reflected in everything we do.”
