Alan Harper — Principal


  • Bachelor’s Degree in elementary education—Minnesota State University Moorhead   
  • Master’s Degree in educational leadership — Minnesota State University Moorhead   
  • Master’s Degree in education/curriculum and instruction—University of Phoenix 


Previous education experience and number of years in the field:

Mr. Harper brings 34 years of educational experience to this role. He previously served as a principal of Stambaugh Charter Academy, an NHA sister school in Youngstown, Ohio. Prior to his time with NHA, Mr. Harper served as principal of three schools ranging from elementary to middle school. 

Why did you choose education as a profession? 

My desire to teach, coach, mentor, and have a positive impact on the lives of children lead me to this role. There were many people in my past who sacrificed their time and knowledge to support my growth; I feel my role as a teacher and principal also serves to repay that.”


In his free time, Principal Harper loves to spend time with his daughter and grandchildren.
