When Nathan Kastner and Owen Hill met as colleagues at an award-winning tutoring company in Washington, D.C., they became unlikely partners. Though they came from entirely different worlds — Owen, freshly graduated with a master’s degree in Mathematics, Nathan, a New York University-trained songwriter — they immediately saw eye-to-eye on the teaching principles that have come to form the bedrock of Kastner Hill. At the time, Nathan and Owen couldn’t have predicted the legacy they would build. They simply understood that a few important ideas can have a powerful impact: learning should be fun; great teachers should also be mentors; a student is more than a score.

Years later, Kastner Hill Learning has grown into an institution deeply rooted in those principles of compassionate teaching and holistic learning. Nathan and Owen have expanded the KHL team, seeking out talented, like-minded tutors who all believe in that same core mission. But as the team has grown, our record of success is as strong as ever. The numbers speak for themselves: at KHL, students have seen a combined average increase of roughly 200 points per student on the SAT and 4.5 points on the ACT. More importantly, though, Kastner Hill Learning has become a community that fosters positive growth in our students far beyond the confines of standardized testing. Students often return for help with their academic coursework; some even return to work with us, helping to give back to the community they’ve taken so much from. We pride ourselves on being a place where students want to be — where tutors work with students to not only improve their scores but grow into the best versions of themselves.

Even as we’ve grown, Kastner Hill Learning’s foundational principles remain the same as those that drove Nathan and Owen to found this company years ago: success extends beyond a test, and a student is more than a score. We’re confident in an approach that prioritizes the individual needs of our students, and every member of our team strives to meet every single one of those needs. Students deserve to learn from teachers who care, and we stake our success on that care every day.
