So first of all, Dori, what is the CTIA Wireless Foundation?

Every day, we're seeing how wireless technology is transforming lives, the ways students learn, the way we access healthcare.

At CTA Wireless Foundation, the mission of our Catalyst program is really straightforward.

We support bold social entrepreneurs who are using wireless technology to tackle really big challenges in communities.

And so far, we've invested over $2 million in these social entrepreneurs, and the results are just incredible.

They have touched over 35 million Americans all across this country.

It's powerful to see how Catalyst winners are really harnessing the power of wireless technology for public good.

So how are this year's finalists using wireless technology in new and unexpected ways to tackle real world challenges today?
