I am dedicated to building quality-crafted websites driven by JavaScript that are as beautiful and interactive as they are functional.


Since 2015, I’ve taught over a thousand students the basics of web development at General Assembly. I believe wholeheartedly that learning can and should be fun.

Instructional Designer / Subject Matter Expert

Since 2016, I’ve been writing curriculum and building courses for General Assembly. I love breaking down complex concepts for beginners.

Sarah Holden is an amazing instructor. She always went above and beyond to help me out when I was stuck. Her keen sense of design made her presentations and labs more engaging. She exemplifies who I want to become (a superhuman designer/developer hybrid).

Sarah has been a joy to work with at General Assembly. Her knowledge of the content is amazing and she is always willing to go above and beyond what she has to do as an instructor to make sure her students are successful. She also has the ability to work with diverse populations and adapt to needs of beginning learners. I would highly recommend Sarah for Programming and education jobs in the future.

— Gabe Nelson

Sarah was a fantastic front-end web development instructor at General Assembly. Sarah’s knowledge and patience made the learning process that much easier, especially for the daunting world of JavaScript! I strongly recommend Sarah as an web development instructor or mentor and hope our paths somehow cross in the future!

— Rory Baumstein

If you have the opportunity to work with Sarah, seize it. Sarah is, without a doubt, one of the most reliable, kind-hearted, and talented people I’ve ever worked with. I worked with Sarah since General Assembly Chicago opened its doors, and she was an absolutely crucial part of GA Chicago’s success and set an amazingly high standard for quality and professionalism.

She’s someone I (and others on my team) could always trust 100%, and I have thoroughly enjoyed working with her. I would recommend her highly to any team!

When I’m not creating things for the web, you can find me riding my motorcycle down the rugged California coastline, hustling at the local billiards hall, or rollerskating backwards at the Moonlight Rollerway.
