Simplify the triangles to just one on each edge. And swap out the turquoise shape for a cloud.

This may butcher some underlying meaning in the Native American community. Not sure if this symbol represents something. Also I’m not sure if these shapes/colors are specific to Navajo’s.

Also, another to consider, what about a dream catcher in the shape of a cloud. Chase your dreams, or something like that. That’s universal with an underlying supporting theme. And yes, I recognize it doesn’t represent “dreams”, but it would to the rest of America whom you’ll be seeking investment. Consider it like protecting the futures of your students.
