ABOUT J.R. MARTINEZ
J.R. Martinez is an Iraq war veteran, motivational speaker and actor on ABC's ALL MY CHILDREN.
In April 2003, at 19, he was serving as a humvee driver for the United States Army in Iraq when his left front tire hit a landmine. He suffered smoke inhalation and severe burns to more than 40 percent of his body. J.R. was immediately evacuated and sent to Brooke Army Medical Center in San Antonio, Texas, where he spent 34 months in recovery. Since his injury, he has undergone 33 different surgeries, including skin grafts and cosmetic surgery. While in recovery, he started speaking to other burn patients within the hospital, sharing his experiences and listening to theirs. News of his story and efforts to help others quickly spread, first on a local level and then to national circuits, leading to appearances on OPRAH, 60 MINUTES and CNN. J.R. has traveled the country since 2004, spreading his message of resilience and optimism. He joined the cast of ALL MY CHILDREN as combat veteran Brot Monroe in 2008. Martinez now calls Dalton, Ga., home.
