Our Teachers

By being an online school, BlockSchool can hire world-class teachers available at the times you need them. All of our teachers are native-English speakers, have experience teaching kids, and know how to code. Every teacher must pass our rigorous interview process too.
Due to our high bar, we only hire ~5% of the teachers who apply.

Featured Teachers

Walker Steere

College: University of Washington
Hometown: Menlo Park, CA
Jobs: Data Analyst at Facebook


I grew up in Menlo Park California and currently go to the University of Washington to study Applied Mathematics. I have been coding for about five years and work primarily in Matlab and SQL now. Growing up, I loved expressing creativity through LEGOs. I really enjoyed the structure and symmetry that they offered and I see a lot of creative parallels that can be accessed through coding. I think coding doesn’t always have to be a rigorous activity (though it certainly can be). In my free time I like to hike, play sports, read and enjoy music.

Justin Zeng

Jobs: Software Engineer at Microsoft (Beijing, China)


My name is Justin, and I’m a Computer Science student at the University of Illinois. My experiences with one-on-one English tutoring and entertaining kids at orphanage visits have taught me patience, humor, and compassion. I started learning coding in middle school through projects like Scratch. I have experience with several languages, including Java, Python, and JavaScript. I enjoy coding, and I hope to spread my passion to others. I look forward to teaching your kids!
