Dr. James Mosley Named New Superintendent of Third Ward School
with Unique Educational Model
HOUSTON, TX (August 10, 2023) — Dr. James Mosley, has been appointed Superintendent of Yellowstone Schools in Houston’s Third Ward. Unique in its model, the school operates a private Christian Pre-K through 5th-grade school, and a public charter school which is growing to 12th grade on a new and expanded campus. Yellowstone will be welcoming a new 9th-grade class to launch its high school this year.
Mosley, who has been serving as Yellowstone’s Chief of Schools, was selected by the Board of Directors following the announced departure of Superintendent Ryan Dolibois to become the founding Executive Director of the Sarofim Foundation.
“James is uniquely qualified to lead the next chapter of Yellowstone’s growth,” says Board Chair David Dominy of Dr. Mosley’s appointment. “He has led our academic program, managed our school instructional leadership and played a critical role in the advancement of our educational model. We are confident that he is the right individual to advance our students into our next generation of leaders.”
A native Houstonian, Mosley has more than 15 years of educational experience in Houston. Prior to joining Yellowstone, he served in campus leadership positions at YES Prep Public Schools. He also has been an educator at KIPP Polaris Academy for Boys and other charter schools in the Houston area. Mosley has a doctorate in education from Baylor University.
Additional Yellowstone Leadership Changes
In addition to Mosley’s appointment as Superintendent, Marian Williams joins Yellowstone Schools as its new upper school principal. Williams, who began her career with Teach for America, is a highly experienced educator and has been recognized for her leadership, improving performance at schools in Memphis and Beaumont before coming to Houston. Yellowstone board member Ken Cowan, a Senior Vice President at Enchanted Rock, has been named upper school board chair. Additionally, Amy Tanner, formerly Yellowstone’s Chief Advancement Officer, has been named Chief of Staff. Tanner has held positions in advancement and marketing in Houston’s non-profit sector for more than 20 years.
About Yellowstone Schools
Rooted in the Christian faith, Yellowstone Schools educates 600 children in Pre-K through 9th grade, and will grow a grade each year to serve 12th grade by 2026. Yellowstone partners with students and families—regardless of financial means—to provide a life-changing education, develop faith and character, and prepare scholars for life beyond high school. The sprawling campus is located in the Third Ward, one of Houston’s oldest historically Black neighborhoods. Yellowstone Schools consists of our lower school (a private Christian school serving PreK-5th grade) and our upper school (a tuition-free, public charter school growing to serve 6th-12th grade). Though two distinct legal and financial entities, we collectively refer to ourselves as Yellowstone Schools to reflect our shared mission, vision, values, culture, and leadership.
