Dr. John Walker is a proud 2015 alumnus of Emmaus University, an experience he often describes as one of the most formative and joyful seasons of his life. During his time at Emmaus, he was actively involved in campus life, serving in student government, participating on the basketball team, working on the maintenance staff, and engaging deeply in the spiritual and relational community that shaped his personal and vocational calling.

Dr. Walker currently serves as Superintendent of Central Christian School in Hutchinson, Kansas, where he has provided strategic leadership in advancing the school’s mission, strengthening academic programs, and leading multiple successful capital campaigns. Under his leadership, the school has also achieved key accreditation milestones, positioning it for continued growth and long-term sustainability. In addition, he serves as a Congressional Fellow in the United States House of Representatives and contributes to higher education as an adjunct faculty member for several institutions, including Lancaster Bible College and Central Christian College.

Following his graduation from Emmaus, Dr. Walker returned to campus from 2016–2018 to serve as Director of Campus Life, a role he considers a privilege as it allowed him to invest in students in the same way he had been poured into during his undergraduate years. His continued connection to Emmaus reflects a deep gratitude for its Christ-centered education and enduring impact on his life and leadership.

Dr. Walker and his wife, Sarah, have been married for 15 years and have four children, two of whom were born in Dubuque during their time at Emmaus. In addition to his professional work, he serves as an elder at Grace Bible Church. He is also an accomplished author and speaker and enjoys competing in endurance sports.
