Esther Stief Profile

Esther Mellinger Stief

Executive Director

A steadfast advocate of learning and the pursuit of higher education, Esther Mellinger Stief has served as the Executive Director of Crossroads Foundation since 2017. Prior to accepting the position of Executive Director, she worked as the Director for Research and Program Development of Crossroads for five years.

Esther first began her career in education as a high school English teacher, working with students in the classroom for 10 years.

When she has a moment of free time, you'll find Esther outdoors — hiking, kayaking, skiing, or biking with her family and friends. She's also an avid reader and is usually in the middle of two or three books.

"Working at a small nonprofit like Crossroads provides opportunities for getting involved in almost every part of the organization's functioning — there is always a new challenge, creative idea, or beneficial program to become engaged in. I like being able to immediately problem-solve, measure impact, and effect change; I'm never bored. But most of all, working at a small nonprofit allows me to work tangibly toward our mission every day as I interact with our scholars and see firsthand the results of the work our team does."

Crossroads is where I spent my time in high school as a scholar. And when Sister Sandy gave me her key to the building as an employee, I said... "It's about time!"
