Financial aid

We believe that diversity breeds strength in our community and we want a Sunstone education to be within reach for as many families as possible. To encourage a diverse socio-economic community, we offer need-based assistance. This year we have awarded $194,000 in tuition assistance to 20% of our student body.

Ask us about the financial aid we offer and how to apply—we’ll help you understand what may be available.
