NAUMS, Inc. Leadership

Chief Executive Officer

Barbara Nicholson Freeman, M.Ed.

Barbara Nicholson Freeman brought thirty-six years of educational training and experience to NAUMS, Inc. in 2002, when she became its first Executive Director. Having served in both public and private schools, she believes the University-Model® is an excellent alternative in education. In her opinion, it is the best of the three options (public, private, University-Model®), especially for parents who desire time with their children, combined with quality Christian education. Mrs. Freeman’s educational credentials include a B.S. in Elementary Education from Delta State University, a Master of Education and a Master of School Administration, both from the University of Texas-Rio Grande Valley. She holds Texas (TEA) lifetime certification in teaching, instructional supervision, and school administration. Her K-12 experience includes thirty-three years in public education and twenty-one years in Christian education. Prior roles include teaching, public relations director, federal programs supervisor, central office administrator, elementary and high school principal, and superintendent. Mrs. Freeman has two adult children, six grandchildren, and eight great grandchildren. 

Mrs. Freeman was named Chief Executive Officer of the NAUMS, Inc. corporation in 2015. She resides in Mansfield, TX, and is married to Chuck Freeman, a Ft. Worth architect and partner with Callahan & Freeman, Architects. 

Senior Executive Officer & Pastor 

Dr. John W. Turner, Jr., D.Min.

John married Roxie in August, 1975. They are blessed with five children and 18 grandchildren. Dr. Turner serves as Senior Executive Officer of NAUMS, Inc., the parent corporation of University-Model ® Schools International (UMSI). John began his experience with the University-Model® when in 1993 he and Roxie enrolled their oldest two children (previously homeschooled) in Grace Preparatory Academy, Arlington, Texas, on the first day of the school’s inception. Four of their five graduated from Grace Prep. After the Turners moved to Glen Rose, Texas in 2004, their youngest graduated by way of the Turners’ home school. All five are college grads today. From 1998 until 2004, Dr. Turner served as Grace Prep’s first full-time Dean of Character Development. In 2001, he wrote the definitive book, Character Driven College Preparation, to provide a quick overview of the University-Model®. In 2017, he authored the updated and expanded edition, used today to orient all parents, educators, and administrators to the model’s mission and method. Dr. Turner has served continuously as a pastor of churches since 1981–first in a full-time capacity and then bi-vocationally. Presently, he is pastor of New Prospect Baptist Church, Nemo, TX. Since 2008, Dr. Turner has also been Executive Director of Father’s House Educational Foundation, a Christian non-profit ministry that builds and hosts group journeys for believers to the Holy Land. John and Roxie personally host an average of three to four educational groups per year to Israel and other Bible lands. Dr. Turner wears three ministry hats each week: Pastor, Senior Executive Officer of NAUMS, Inc., and Executive Director of Father’s House.
