Simmons helped found “The Children Matter,” which is an organization that fights to get kids around the world access to health care.

“You have a cavity, you go to the dentist. Most of the children out there can’t do that. Bad eyesight, bad hearing, and it gets much, much worse,” Simmons said. “So I, along with [the Twin Cities charity] Matter, are going to change all that. And we don’t want to get too heavy-handed and try and make you cry about it. Let’s celebrate life but also do some good.”
