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 Francisco - West Portal, 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. That's why our after-school coding classes for kids revolve around this relationship, providing a long-term mentor in a Code Coach to teach kids to code, from someone who's an expert coder themselves. Located near top schools like Lowell High and Clarendon Elementary, theCoderSchool San Francisco in West Portal sits on the southwest side of San Francisco in the heart of West Portal. Looking for a location north of Golden Gate Park? Be sure to check out our other San Francisco location in the Richmond District.

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.

theCoderSchool System

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

  • "The coaches at The Coder School have captured the attention and focus of each of my 3 kids, even though none of my kids are naturally drawn to coding. Doesn't matter what day, or what coach, or what kid - The Coder School hires great coaches and does an excellent job matching students to teachers, so that every child loves their time there. The flexible curriculum has really allowed our kids to explore what interests them, and cover more languages than they would be exposed to if bound my a more prescribed curriculum. The manager, Allen, is always super responsive and easy to communicate with for any scheduling needs. Top notch customer service."
    Laura S, San Francisco
  • "Kids (and adults!) play way too many video games nowadays. We were happy when we saw that The Coder School had opened up in West Portal. We were thinking about attending another program on the other side of the City. We wanted our kid to spend some time on the other side building these things, and he was definitely interested in trying. We've been happy with the place. Allen is always welcoming, and makes you and your kid feel at home. My kid has been working with Carolyn, who knows her stuff and gets along well with my kid. As a self-confessed (sometimes!) helicopter parent, I am usually there when my kid has class trying to get some work done. I can hear other lessons going on, and can tell that the coaches are knowledgeable, and able to work well with the kids. We have never taken group lessons, so my experience is with the private / semi-private lessons. We recommend them."
    Jamie F, San Francisco
  • "My son has been taking lessons at the coder school for several years. He's become proficient in a variety of coding languages and concepts, and is now creating full image games in Unity and system tools in Python. The coaches he has had over several years have all been incredibly supportive, but also challenging in a good way. And of course its all about that he has fun and is getting challenged appropriately. But there's also the parent side of things too. Allen and his team are incredibly patient with adjusting to the ever changing after school schedule and ensuring that my son has the right coach for the right time in his learning. When he was younger, getting coaches who were energetic and supportive in lighter languages was the most important thing. As a high schooler now, its more important that the coaches become more heavyweight both in terms of the concepts being taught, but also in expectations. The team at coder school have been excellent in putting in the right resources at the right time, and working right with our schedule. Couldn't recommend the coder school more!"
    Jay M, San Francisco
  • "My 5th and 7th graders having been coming to the Coder School for over a year. Both of them like their teachers, Jacky and Caroline, so much that I'm making the trip here twice a week so that they can each stay with their respective teacher. The low student teacher ratio allows the teacher to really understand their level and teach at their pace. They've learned Python, HTML, amongst other languages, to create games and websites that they're proud to show me after class. Bonus, the manager, Allen, is awesome and super easy to communicate with. Highly recommend!"
    Jen J, San Francisco
  • "Since my son plays so many games and uses so many apps, I figured it makes sense for him to learn the building blocks of how those digital products are made. While, at times, he has felt overwhelmed, I think he has finally found his comfort zone. In a nutshell, The Coder School ensures that your child will learn as much as they want, but more importantly provides a sense of community for kids of all ages, interest levels and skillsets."
    Art D, San Francisco
  • "You've taught me logic as way of thinking and being patient. You're complicated and intricate especially Python 3. However I love making you work and I love all the challenges that you throw at me. If you think about where everything is going, coding is the future in terms of AI and everyday technology."
    Bradley C, San Francisco
  • "My 8-year-old son just finished a week of camp there, and I think he'd move in if he could! He had a great experience there, and seems to have a learned a lot. The staff was excellent - they really seemed to connect with kids, and were enthusiastic about introducing coding concepts to them. They were always available to answer questions and talk a bit about what my son had worked on during the day. We'll definitely be back next summer, or may check out their after school programs this fall."
    Michelle S, San Francisco
  • "Owners, manager Allen, and instructors (Max) in SF West Portal are involved and very encouraging to our two boys. Both loved summer camps and weekly group instruction tailored to their interests and abilities."
    Jeff L, San Francisco
  • "The Coder school is a great place to learn to code. Kids learn at their own pace but are always encouraged to push their boundaries and learn more. The 2 kids to 1 instructor sessions means that kids really get time to explore with a lot of hands on guidance. Coding is my son's favorite after school activity!"
    Helene K, San Francisco
  • "Our 10-year-old son Kyle has been attending coaching sessions at The Coder School for over two years. He has really loved working with Allen and the team in West Portal, and he has learned so much. We also appreciate how accommodating and flexible Allen and the rest of the crew is. Thanks so much for supporting and coaching Kyle. This kiddo loves coding!"
    Amy S, San Francisco
  • "My son loves the coder school - their camps and their after school classes - the teachers and the owners are awesome. We will be long time clients."
    Kate L, San Francisco

Our Upcoming Events

Code Class Series

Scratch Game Design Code Class Series

This beginner group class teaches coding through game design and fun-filled projects on MIT's popular "Scratch" platform. Scratch uses drag 'n drop blocks that allow students to assemble code quickly and create as far as their imagination takes them. In addition to learning computer science fundamentals like loops, coordinates, and variables, students apply and develop core math skills including coordinate geometry, negative numbers, angles, and boolean logics.

Ages: 8-10 years old.
Class Structure: One hour per week TBD 
Location: San Francisco West Portal, 231 West Portal Ave

Junior Code Class Series

We designed a junior code class for our youngest technologists. This code class will mainly focus on keyboarding skills and basic computer science fundamentals using drag 'n drop logical concepts. Your younger technologist will stay engaged with interactive online tools and entertained through games and stories. Space in the Junior Code Classes are limited, so reserve your spot today! 

Ages: 5-7 years old.

Meet Coach Ivy!

At the Coder School San Francisco, we love teaching coding. We also love celebrating our students, coaches, and staff who are such an important part of our community.

Coach Ivy is both a student and Code Coach. Ivy joined us for our first summer camp in 2017 after finishing 6th grade at Denman. She took all of Allen’s whiteboards to organize and plan her text based adventure game. (Allen laughs when remembering how he looked everywhere for the missing whiteboards.)

“That game was one of the first projects that really stuck with me – didn’t feel like an assignment, more like a piece of art.”  -- Coach Ivy

After summer camp, Ivy joined our Code Coaching program as a student. Her first teacher was Coach Natalie, who taught her the importance of collaboration. While Ivy was at first a bit nervous about our pairs approach, where we have two students with one Code Coach, she became good friends with her pairs partner Ethan. Ivy and Ethan are still friends, which is part of what makes us happy about our community – having more students get to know others with similar interests and stay in touch. She also credits Natalie and Ethan for teaching her about the joys of teamwork, mentorship, and of course, readable code. 

Ivy joined us as a summer camp counselor for 2017 and part of 2018. With all her experience as a student and enthusiasm and leadership as a counselor, we were thrilled that Ivy joined us as a teacher last fall after shadowing Coach Jason over the summer.

Coach Ivy enjoys teaching Scratch in particular and has observed that among the benefits of learning coding as a kid, beyond active coding itself, is that you learn to do math and you learn to spell. Fundamentals in a fun way.

Coach Ivy is now a junior in high school who leads her robotics club. She still enjoys learning advanced coding while teaching the next generation how to code text adventures.

Meet Coach Ivy! (continue)

What’s next for Coach Ivy?
“I still have a hard time wrapping my mind around the idea that making video games is a viable career. In my heart, it seems like too much of a pipe dream.

I definitely think I’m going to keep coding forever. It’s one of the best outlets for me to be creative. Even if I’m not in a field using it professionally, I will still make stuff for me for fun regardless of whether there are financial benefits.”

Our hunch is that Coach Ivy will realize her dream and do many great things in addition to her teaching and creating. We’ll be behind her all the way!

“I think people should see code as more of an art than they do.” -- Coach Ivy

Congrats to our amazing coaches

for winning several awards in the inaugural Game Jam Game Design Contest.

Community Services

We were pleased to kick off 2019 by co-hosting a conversation with parents and kids on electronic gaming at SFPD's Taraval Station community room. We talked about balancing gaming time with other activities and setting clear rules and expectations for kids. We also discussed how coding and game design can be potential careers for kids who love games and want to engage that passion. This is a hot topic that we enjoyed talking about! If you are interested in having us host a similar discussion with your school or parent community, please email

Our Schools

Meet Our Owner and GM

Allen Kwan

Hi there! My name is Allen and I’m the Owner and General Manager of the Coder School San Francisco. I am excited to bring the Coder School to the San Francisco bay area when I was born and raised. My Bachelor’s degree is in Finance and I am a proud alum of San Francisco State University. I remember my first experience with a computer: arguing with my older brother over who could play the original Starcraft game first. It took a week to finally get a chance to play, but I was instantly obsessed with gaming, computers, and technology. Making technology more accessible to children is the biggest reason why we’re opening the Coder School San Francisco. I can’t wait to meet all of you and to help shape the future of your little technologist.

And the Other Owner!

Lee Hsu

Hi all! My name is Lee Hsu. I’m a co-owner at the Coder School San Francisco. As an EdTech consultant and teacher, I’ve designed technology curricula and taught computer skills, digital citizenship, and coding to over 1,000 students in San Francisco schools. I've seen firsthand through my work and teaching that high-quality coding instruction is critical for jobs of the future. And, I know from my time studying at the University of Texas and at Stanford University that education must keep pace with modern trends to prepare kids to be future technologists, creative professionals, and leaders in every industry. We have a wonderful team here at the Coder School San Francisco. I look forward to being part of your child's learning and coding journey.
