Allen joined Breakthrough coming from a  strong interdisciplinary academic background and a passion for education. A National Merit Finalist thanks to an aptitude for the PSAT,  he was then offered a full academic scholarship to Michigan State University where he spent 4 years at the Honors College studying humanities (English, Psychology, and Philosophy) and volunteering as a tutor for gifted high school students throughout. After graduation, he worked independently as an English-language tutor in Spain for several years, and spent a decade working as a lecturer and supervisor while pursuing his masters and PhD in Social Psychology at the VU University in Amsterdam. After completing his dissertation he returned home to the States and met Harriet - through luck or fate - an both recognized an opportunity to make the best use of their skills. After shadowing her lessons, understanding her approach and methodology  he began working as a tutor, and in 2021 officially took over as owner and verbal instructor. We believe that with Harriet continuing to contribute her expertise and mentorship, Breakthrough is in an excellent position to continue providing expert tutoring to students in the DC Area for many more years to come.
