In addition, Erik has… • Scored in the 99th % on his SAT/ACT math and science portions • Strong experience teaching students with learning difficulties (including dyslexia, dysgraphia, ADD and anxiety) • Complete mastery of high school math and physics at any level – including the first couple of years of college courses • A desire to teach students of all skill levels Erik’s passion around academics is pervasive. In addition to all of the above, he’s discovered, or helped discover, more than two dozen extrasolar planets. Since we’re not astrophysicists in our spare time, you’ll have to ask Erik what ‘extrasolar’ means.

She notes, “My first student was my little brother, and I'll always value the time we spent working together! My favorite session was one we spent on A Tale of Two Cities, when it finally clicked with him that reading books from 150 years ago could help him think about his own life.” A fellow bibliophile, Shelbi tries to read at least one book a week, which she has to balance with watering her 24 houseplants regularly.
