Meet Patrick. He's 15. He was born deaf. He's from a relatively remote part of Uganda. Because he hadn't had access to any schools for the deaf, he hadn't been able to move beyond simple communication with his father.

Raymond recently returned from an intensive sign language class where he learned to teach others. He just started a 10-week course for the deaf of Patrick's community.

Even as early as the first day of class, you can see a difference.

Now see what a difference 10 weeks of classes made for Patrick and his peers.

It's an understatement to say these classes were life-changing. There are tens of millions of people like Patrick all over the world. If this is what 10 weeks can do, we can do a whole lot more to make a difference.
