"I promised the families that if I ever got an opportunity to try to intervene in a way that could prevent this, I would." —Dr. Mike Kretz, River Falls

Dr. Kretz was a family physician who treated quite a lot of people who suffered from the effects of secondhand smoke.

All too frequently, he saw children who needed to have tubes surgically put in their ears due to recurrent ear infections. Eventually, he decided he could provide more help for more people if he left his private practice. So he became an advocate for public health.

Among other things, he now educates the greater public about the physical dangers of secondhand smoke.

"...what families need to understand within their own homes is that this stuff [secondhand smoke] is really toxic," he explains.
