English+ was created by Bert Leatherman, a graduate of Williams College and a former management consultant at McKinsey & Company. At Williams, in addition to his degree in economics and psychology, Bert was among the first students to complete the certificate in leadership studies, was awarded a Watson Fellowship for a year of post-graduate cultural exploration overseas, and received the Turner Citizenship Prize, the college’s highest honor, given to a graduate committed to the wellbeing of others. Before launching English+, Bert helped found a financial-services startup in São Paulo, earned a master’s degree in international relations at Universidade de São Paulo, and worked as a math teacher at Graded (the American school of São Paulo) and as a private math and science tutor and college-prep coach for students at top São Paulo international schools. Brazilian students he tutored or coached have been admitted to over 100 universities in the United States including Stanford, Yale, Columbia, University of Chicago, Duke, Pomona, Brown, Northwestern, Cornell, and Georgetown. His love of languages led him to earn a master’s degree in French from Middlebury College, where he also served as a bilingual assistant in the Portuguese School. In addition, he holds a law degree from New York University and has worked as a math teacher in a range of schools in the United States, from a top-tier private school in a major city to a disadvantaged public school in a rural area. Bert is a citizen of both Brazil and the United States.
