Our Instructors

Steve Sandweiss – Seattle, Bellevue, Tacoma

Steve Sandweiss has been helping students prepare for entrance exams for college, grad school, law school, and business school since 1991. For seven years he worked for Kaplan, the nation’s largest test prep organization. In 1998, he decided that he could offer better quality courses at more affordable prices to Seattle-area students, and formed Sandweiss Test Prep. He felt it was important to provide smaller class sizes and opportunities for individual attention for students to fully realize their test-taking potential.

Steve teaches and tutors the SAT, ACT, GMAT, GRE, ISEE/SSAT, and LSAT, as well as specializing in certain SAT Subject tests, general school subjects, and college application essay assistance.

Darin Arbogast – Seattle, Bellevue

Darin has been conducting STEM classes and tutoring for the Seattle home-school community for the past 5 years. He enjoys the mental challenge of a good problem, and you’ll often see him indulging in logic games and puzzles. While teaching allows him to share this enjoyment, he finds collaborating with his students in refining the problem-solving process even more rewarding.

Until very recently, Darin was an aerospace engineer with numerous patents and technical publications on his resume. Prior to his time in industry, Darin served as an instructor and lecturer of Modern Physics and Electrical Engineering at Montana State University. He holds a MS in Physics from Montana State University and a BS in Physics from Southern Oregon University.

Aside from teaching, Darin played lead-guitar in a local band for several years in his 20’s. You can still find him on stage (and backstage) in several musical theater productions each year. He also has expertise in pre-industrial woodworking techniques, embedded systems, and robotics.

Darin teaches SAT/ACT, SSAT/ISEE, SAT Subject Tests in Math (1 & 2), Physics and Chemistry, and he also tutors all levels of high school math, including AP/IB courses in algebra, geometry, pre-calculus, Calculus AB and Calculus BC.
