Who is theCoderSchool

Code Coaching®

Code Coaching® is our core philosophy, and what our school is all about!  We believe that every student is different, and that kids should learn in the way that works best for each child. How? Our Code Coaches® - they're the magic sauce!  Unlike some coding schools, we don't just leave the kids in front of a computer, expecting the software to teach them how to code. Nor do we force all kids to go through the same curriculum or projects, regardless of their skills and interests. Instead, our Code Coaches® customize their lessons for each child, and focus on a 2 on 1 mentee-mentor relationship with our kids so our students can get the focused attention they need.

Code Coaching® works for kids of all ages and skill levels, from novice to advanced. From game development to web apps, Python to Java, or even niche technologies like AI and beyond, our Coaches can help your kids achieve their goals.

Sessions run one or two hours a week (your choice), at the same time every week on a schedule that works for both you and our assigned Coach. Check out our video for more info!

Coding Lessons for Kids in San Mateo, CA

Coding takes practice, and we believe getting kids to code consistently throughout the year is the only way they'll really learn to code. theCoderSchool has a staff of hundreds of Code Coaches all around the country, so we know a thing or two about mentoring students in computer science.

Programs at theCoderSchool

Our coding school's flagship after-school program, Code Coaching®, combines a super-small 2:1 teaching ratio with individualized curriculum so kids are able to move at their own pace, doing things that interest them most. While Code Coaching is our premium program, we also offer a more traditional Code Class for those looking for either software-driven or static-curriculum teaching in a larger ratio. And during summer and holiday breaks, we offer Coding Camps. When available, programs are offered in both in-person and virtual formats. Contact us to find out more and get a free trial today.

We're part of a nationwide system of passionate owners in over 55 locations around the country, teaching over 6,000 students every week with the brainpower of 800+ expert Code Coaches®. We're proud of the impact theCoderSchool has had on communities everywhere since our brand was founded 7 and a half years ago, way back in August of 2014. In short, we know a thing or two about teaching kids to code - so let's get to it!

What Kids Learn

We believe that every student learns in his or her own way, not only in what they want to work on, but how fast and how much. Our Coder Tree® is a visualization of our students' learning options as they grow and a sampling of some of the topics we teach. Find more details about what kids are learning by checking out our Coder Tree®.

Our Testimonials

  • "Extremely helpful staff. We love the intimate coaching. My son is learning a lot (scratch, python) and looks forward to each week we are there. Well run and I'd highly recommend."
    Kristina K., San Mateo
  • "Olga is a great manager, very nice, friendly, and accommodating. My son works with Deanna who is a perfect fit for him. His interest lies in hardware and electronics and it just took off with Deanna more so than any of the other coders he worked with. She could help merge his hardware interests with coding and now he really looks forward to his sessions. He also loves participating in the coder fairs where he can display his creative projects."
    Steve T., San Mateo
  • "My son has been taking coding lessons here since first grade and we love it. At first he was in a class, but he likes to work on his own projects, so we switched him to one-on-one lessons. He has learned an amazing amount of coding very quickly. I like the instructors he has had and I've found them to be responsive and easy to work with when I need to make schedule changes. Learning coding has helped him build confidence and independence, and I'd recommend it for any age."
    Lucy Y., San Mateo
  • "My son has been going to the Coder School San Mateo for three years and has been enjoying it. The project-based approach seems to work for him and keeps him interested in coding...We appreciate the fact that each time right after the session, we will receive a message from the coach with details about the lesson and areas of improvement my son should focus on. Messages like that are very helpful for us. We feel lucky that my son has a coach who is not only knowledgeable in coding but genuinely cares about the well-being of his students."
    Kokil C., San Mateo
  • "Both of my daughters have been taking classes at The Coder School for the past two years. They truly enjoy creating their own games and learning from Olga and Deanna. They have been particularly patient and helpful as we have been sheltered in place!"
    Carla H., San Mateo
  • "My son has been learning at San Mateo Coder school for a few years. They did in person group classes for 2 years and then took 1 year off. He is now doing remote codine 2:1 with his best friend once a week. He really likes the remote class and the semi- private custom class. We have been with Coder school since it opened in San Mateo and we love the services. Olga is excellent and fast with communication. The school hires really good teachers. And it has grown and adapted to the COVID changes well. I highly recommend it."
    Emily F., San Mateo
  • "My son is really enjoying his class. He’s get personalize attention and sees the benefit of the program through completion of projects. In a short time, he’s already completed several games."
    Maricar P., San Mateo
  • "The Coder school has been such a great experience for my 9 yr old son- he started from Scratch and now doing Python and enjoys both. The staff at the San Mateo location has been super helpful in terms of flexibility and accommodating personal needs. I've noticed teachers on Zoom giving him personal attention to make sure he understands and finishes his project. Recommend without any reservation."
    Flavia D., San Mateo

Our Schools

Meet Our General Manager


Hi there! My name is Harry Clemente, and I am the general manager of theCoderSchool San Mateo. I am passionate about fostering growth and empowering others! I have a B.S. in Business Management from San Francisco State University. I have worked as an instructor in the autonomous car industry, and as a martial arts coach at my academy. During the pandemic, I took a leap of faith, and completed a Software Engineering Immersive at Hack Reactor. In just 4 months I went from understanding basic data structures and algorithms to building full stack mobile and web applications. My mission here is to provide a healthy environment for kids to build engineering skills and develop applications that are interest-focused. Coding can be fun, and when we have fun doing it, we can’t help but get good at it! I’d love to answer any questions at

Meet Our Senior Coordinator


Hey everyone! My name is Cinthia and I’m the Senior Coordinator at theCoderSchool San Mateo. A little about me- I speak English and Spanish fluently and attended CSM as well as a program here in San Mateo towards an AS degree to become an MRI tech. I grew up in Silicon Valley in the 2000’s so obviously technology had a huge impact on everyone’s lives- I was lucky enough to know how to edit my Myspace profile at the age of 7 with some basic copying & pasting which I later found out was a form of coding. I look forward to working with your children and hope to contribute to their success especially now that the pandemic has shown us how important technology and coding is and how it will impact your children’s futures. Feel free to contact me with any questions at
