St. John's Northwestern

Since 1884, St. John’s Northwestern Academies has served as an independent, private college preparatory school in Delafield, Wisconsin. We offer both boarding and day school for aspiring boys and girls from middle school through high school along with post graduate programs.


Our mission at SJNA is to educate and develop young men and women to be responsible citizens, as well as moral and ethical leaders who are inspired to take advantage of today and tomorrow’s opportunities. SJNA founder Sydney Smythe felt that "the way to get the most out of a student is to make them reach just a little farther than they had supposed their arms could stretch."


Through a strategic partnership with DME Academy, out of Daytona, Florida - SJNA now offers a unique pathway for student-athletes that demand more from their athletic and academic experiences.
