Why Mosaic

Sure, it takes grades to get into your dream school. Grades tell an admissions officer that you can do the work. But it doesn’t stop there. Grades are only the first criteria in a process that gets more competitive every year.

Today’s top colleges are searching for students with unique talents and aspirations. They will scour your application for opinions, statements, passions, hopes, dreams and fears. They want to know what you’ll do to make their school a little different. They’re not necessarily looking for the class valedictorian. They’re looking for someone like you.

Unfortunately, many people get lost in the admissions process. It’s intimidating. The essays can be overwhelming. And you can wind up looking at a blank screen, attempting to outguess the admissions officer, trying to be someone you aren’t.

Our Team

Mosaic’s team is comprised of talented, diverse professionals with extensive experience in college admissions, writing, marketing, the arts, and business development. We are storytellers at heart and will help you convey who you really are.
