Nathaniel McDonald, Head of School

nathanielmcdonald (at) montessorihighschool (dot) org
Nate McDonald is honored and privileged to serve as Head of School, leaving his post on the Board of Directors and returning to Montessori education after a career as a lawyer. Nate was raised on a farm in Chardon, Ohio and his family has deep roots in Cleveland. He is a graduate of Kenyon College, where he double majored in English and History and played varsity baseball. After earning his Montessori Elementary Teacher’s Diploma in Bergamo, Italy, Nate was a member of the founding faculty at the Hershey Montessori School Adolescent Program on the Farm. He developed curricula and taught humanities, geometry, occupations, and music; shared his passion for music and sports with the students; and enjoyed working with adolescent boarding students as a member of the residential faculty. The experience as part of the learning community on the Farm inspired Nate to go to law school, where he graduated first in his class at Cleveland-Marshall College of Law. After law school, Nate worked as an Associate at a large business litigation firm and as a Judicial Law Clerk for Federal Judge Kathleen M. O’Malley. Most recently, Nate worked as an Assistant Public Defender in the Cuyahoga County Public Defender’s Office, representing indigent criminal defendants before Cuyahoga County courts and in the Ohio Supreme Court. While deeply committed to indigent defense as a critical component of social justice, Nate believes education is the most important social issue of our time and views his work against the backdrop of Maria Montessori’s unifying insight: the ultimate goal of education is peace. Nate lives in South Euclid with his wife, Karen, and their three young children—Meadow, Rosemarie, and Dylan. His daughters let him play in their ukulele band (“Daddy and the Chicken Hawks”), and he sings and plays banjo, upright bass, and guitar with his extended family in the Cleveland oldtime music scene. Nate also enjoys playing morning basketball, coaching T-ball, following Cleveland baseball, spending time at his parents’ farm, being at home with family, and daydreaming about finding time to read for pleasure.
