Sam Aleinikoff

Sam Aleinikoff

Founder & Executive Director

Sam began his career in education, teaching math at Towers High School in 2011. Although his students quickly experienced academic success, Sam also watched his students graduate from high school with little guidance and no plans for post-secondary education.

Today, Sam serves as the Executive Director of College AIM. In this capacity, Sam works with school, district, corporate and non-profit partners to expand College AIM's reach to additional school communities and to direct the vision of the organization. Simultaneously, Sam still works as a college advisor for the organization, thoughtfully guiding and fiercely supporting students to and through college.

Sam came to Towers as a Teach for America Corps Member after graduating from Cornell University with a Bachelors of Science in Human Development. Sam was also a 2019 Civic Innovation Resident and 2018 Civic Innovation Fellow at the Center for Civic Innovation, was named to the Young Nonprofit Professionals Network of Atlanta's 30 under 30 in 2018, served as a member of the Class of 2016 with New Leaders Council in Atlanta and was named Towers High School Teacher of the  Year in 2016.
