Hey folks, thank you for visiting.

RefactorU was founded in late 2012 in Boulder, Colorado, and was one of the first accelerated web application development "bootcamps" in North America. Launching its first cohort in 2013, it was the first full-stack Javascript bootcamp in Colorado, the first to be approved by Colorado's Division of Private Occupational Schools, and the second bootcamp in the United States to be approved to accept the Post-9/11 GI Bill and related U.S. armed services educational benefits. Between 2013 and 2017, RefactorU helped over 300 people accelerate and/or completely reboot their careers in a 10-week, full-time, onsite learning experience, and thousands more learners through hybrid and self-paced courses.

In 2017, RefactorU's owners needed to step away from the business for personal reasons, and ceased operations in 2017. As a result, all of RefactorU's courses on Udemy are free of charge, and any courses that could not be made free (due to Udemy's pricing policies), were removed from the catalog. That also means that the content has not been updated since 2017, any messages you send way won't be answered.

Still, we hope you find value in what is here, and we wish you well in all your endeavors. LLAP.
