BISHOP McNAMARA HIGH SCHOOLA Catholic, Holy Cross, Coeducational, College Preparatory School for Grades 9-12


Meet our Principal - Mrs. Dian A. Carter

I always remind students that we all have dreams and aspirations to be something great, but if we embrace the words in James 1:19 and, ‘are quick to listen, slow to speak and always slow to become angry’, God will speak to us in marvelous ways.  He accepts us on our best days and loves us all the same on our worse days, his love is unconditional.

Mrs. Dian A. Carter is the Principal of Bishop McNamara High School who now enters her second year in this position. Mrs. Carter is the twelfth person in school history and the first woman to serve in this key leadership role. 

In her first year, Mrs. Carter guided Bishop McNamara High School with tremendous passion and resolve and led with conviction and concern for the safety and well-being of the entire Bishop McNamara community, evidenced particularly during the transition to full remote learning that began in March and concluded with the end of the 2019-2020 academic year in June.  

Prior to her appointment as Principal last year, Mrs. Carter served as Bishop McNamara's Assistant Principal for two years and she served as the Principal at Saint Ambrose Catholic Academy in Cheverly, MD for nine years. Before beginning her tenure as a Catholic school educator, she worked as a high school English teacher for Prince George’s and Montgomery County Schools. She began her career as an administrator at Bethesda-Chevy Chase High School in Bethesda, Maryland, as an Assistant Principal and prior to leaving Montgomery County Public Schools, she also served as a Vertical Articulation Specialist, Test Coordinator, and Assistant Principal at Wheaton High School in Wheaton, Maryland. 

Mrs. Carter earned her Bachelor of Arts in English Education from the University of Maryland, College Park and her Master’s in Supervision and Administration from Bowie State University.

Mrs. Carter has spearheaded numerous academic and community initiatives during her tenure at Bishop McNamara.  She brings boundless energy to the role as she serves as a wonderful mentor and example to the school's faculty, staff, and students.  As she enters her twenty-eighth year as an educator, she remains excited about Bishop McNamara present success and bright future.  Mrs. Carter is an administrator who possesses high standards and expectations of student conduct and she remains committed to fostering a culture of respect among students, faculty and staff. As the parent of two Bishop McNamara alumni, Mrs. Carter is dedicated and enthusiastic to support the teachers, students, and parents in every way possible.  Through her words and actions, Mrs. Carter advances Bishop McNamara High School’s mission to educate hearts and minds in a dynamic, inclusive Catholic school community rooted in the Holy Cross tradition.

I truly believe that becoming an educator was my calling and, twenty-eight years later, with various job titles under my belt, I never once regretted teaching, mentoring, or praying with children and young adults.
