Welcome to Lakeside! Our 5th-12th grade program offers students a dynamic experience designed to support their educational growth and social-emotional needs. Academic excellence is a foundational part of what we do here, and also just the beginning. Alongside a committed and talented faculty, our students grow as people, always refining and developing their own beliefs and values. We encourage exploration. We teach students how to apply a critical lens to the world around them. We affirm that Lakeside is a place where every student can bring their full self. And we know the strength in this community is found in the friendships that extend far beyond this campus. 

We invite you to learn more. 

Lakeside students have a demonstrated joy for learning and a record of academic success within the context of their own experience; a willingness to be open-minded and positively engaged in a diverse community; and the skills, potential, and desire to progress within our program.
