A note from Sergio

As the Founder & CEO of Next Shift Learning, I was inspired to launch our team based on my personal and professional lived experiences navigating where I wanted to add value and impact lives.

My career building and launching workforce programs and initiatives confirmed my belief that intentionally designed experiences — that welcome, celebrate and value diverse backgrounds and perspectives — drive the most innovation, and lead to impactful, lasting results.
