Ludwig Suarez

Ludwig Suarez is an educator whose experiences are the basis for his true dedication to education. Graduating from Columbia University and attaining a B.A. in economics, his successes are illuminated through the contrast with the challenges that he had to overcome. Ludwig had to find within himself the determination, discipline, and resiliency that it would take to help him reach Columbia’s campus. There, his exposure to the Columbia Core, which challenged him to develop in so many facets of his life, affirmed the reformative potential of education. Motivated by this appreciation, Ludwig has taken every opportunity available since to further refine his understanding of the educational process, working as an educator with the Thurgood Marshall Academy for Learning and Social Change, as well as collaborating with educators from Chicago’s Hope Academy and the Double Discovery Center at Columbia University. He hopes to one day work towards affording others greater accessibility to the amazing education and consequent opportunities to flourish as a person that were afforded to him.

Currently, when he’s not helping students with Competitive Advantage, or tutoring in economics courses with Columbia’s athletics department, Ludwig is working towards a lifelong aspiration to be a professional athlete. Driven by the opportunity to be a testament to the efficacy of the principles that have guided him thus far in the realization of any goal, he relentlessly pursues his dream hoping to ultimately inspire others to be unwavering in the pursuit of theirs.
