Executive Leadership


ShaunShaun Luehring Luehring

President & CEO

Shaun Luehring became President & CEO of LUMIN Schools on January 1, 2019, overseeing more than 150 employees and 1,300 students at six Lutheran schools that serve primarily low-income, minority children in Wisconsin and Indiana. He was hired by LUMIN Schools in 2015 to create a network-wide academic infrastructure that established consistency in school cultures, instructional practices and leadership development. In his first three years of service, standardized test scores increased an average of 27 percent across all LUMIN Schools with its Wisconsin-based schools earning ratings of Exceeds Expectations or Significantly Exceeds Expectations by the Department of Public Instruction.

Before joining the LUMIN leadership team, Shaun spent 16 years serving Lutheran schools as a principal, teacher and executive, specializing in school turnaround, leading change, and serving children and families in low-income urban areas. He led several Wisconsin schools through tumultuous times, most recently Atonement Lutheran, which was considered a failing school when Shaun became principal. Under Shaun's leadership, Atonement became the 2nd highest performing school of all 80/80 schools in Milwaukee, serving 80 percent low income and 80 percent African-American students. Test scores increased by 27 percent, and the student retention rate grew to 93 percent along with an attendance rate of 97 percent. 

Shaun also spent five years in California as the principal of Apostles Lutheran School in San Jose where he focused on student enrollment, which increased 15 percent in one year. This role in particular enabled him to work closely with students and prospective families, developing his relationship-building skills that were an essential part of his school turnaround work later in his career. 

Outside of his work at LUMIN, Shaun is an adjunct professor at Wisconsin Lutheran College and a leadership coach for the Center for Urban Teaching. He has served on the board of directors for Choice Schools Association and Grace Lutheran in Grenada, West Indies. He regularly serves as a keynote speaker at education-related events and conferences. He is also an active church member at Salem Lutheran in Milwaukee. Shaun and his wife live in Milwaukee with their three children.
