Yinna Martinez (second from right in pictures) is an Occupational Therapist working at Simón Bolivar Hospital in Bogotá, Colombia.

Her patients include burn victims whose wounds require specialized (and often painful) treatments that help reduce scarring and keep mobility.

Physicians for Peace trained Ms. Martinez and many of her colleagues at a regional burn care conference in Costa Rica in late 2014. One of the techniques taught was creating mouth splints, which help burn victims retain the ability to smile and laugh.

"With regard to the mouth splints," Ms. Martinez says, "I had made similar splints in the past but now I make them using a technique I learned at the PFP training and I have had much better results with my patients because they tolerate them better and for a longer time. In light of all those skills learned, I personally feel that the training was excellent."
