Dan Hertz has been a full-time tutor with Marks Education since 2012. Prior to joining Marks, he was a researcher in particle physics at Cornell University, where he obtained a PhD in 2008. He then conducted research in auditory neuroscience and served as a lecturer for physics courses at the University of Maryland, College Park. 

Dan prepares students for the SAT and ACT and provides academic support for students in a number of different areas. He works with students taking high school and AP level math and natural science (physics, chemistry, and biology) classes. In addition, he tutors students for college-level physics and math courses, including multivariable calculus and linear algebra.

By working one-on-one with students, Dan is able to provide them with an approach tailored to suit their individual needs. He has particular expertise in helping students overcome anxiety and attention-related learning differences. He works to ensure that students are able to relax and open up to him without fear of being judged. As a result, Dan is often able to help them overcome challenges they had previously considered insurmountable. He finds that empowering students to realize their true abilities and potential is the most rewarding part of working as a tutor.

Although his family is American, Dan grew up in Denmark and attended Danish schools before studying physics as an undergraduate at Merton College, Oxford. While there, he rowed in the First VIII for his college and competed at the Henley Royal Regatta in 1999. During his time as a graduate student at Cornell University, Dan served as a counselor, mentor, and trainer for EARS, the university’s peer counseling service and telephone crisis line.

Dan is often able to connect with students because he has the simultaneous fortune and misfortune to find almost everything interesting, from cellular biology and ancient warfare to pencil sharpening and music theory.

Dan is available to tutor students virtually and in person in the Bethesda office.
