Stories of Impact

Discover what our volunteers have to say about their experiences with Operation Smile.

With the treatment provided by Operation Smile, in places where life itself is so challenging, these children are given a chance. An opportunity to eat and drink normally, the ability to speak naturally, and to simply look – and smile – like everyone else. I became a plastic surgeon because I saw how surgery could transform a child’s face. When I began volunteering I saw how the transformation is more than just physical; Operation Smile transforms lives.

Dr. Vivek Panchapakesan, Volunteer Cleft Surgeon

I believe that the work Operation Smile does, changes the world we live in. There is a big lack of safe surgical services across the world and most of the burden is in developing nations.  By joining Operation Smile, I have had the opportunity to use my skills and knowledge to be part of an amazing group made up of  thousands of volunteers who share the common desire to change the lives of those most in need and bring back the smiles of children, families and entire communities. My hope is to continue to be able to bridge the gap of inequality in the world and be able to continue to change the world one smile at a time!
