It's been 25 years since tragedy blindsided Americans on September 11, 2001. On that fateful day, Ron Gaudette, a founding member of the International Medical Surgical Response Team, was deployed to the World Trade Center, making it his first mission. His team arrived just hours after the second tower fell and spent several days on-site, providing medical care and support in the aftermath of the attacks. Ron shared his memories of 9/11, along with stories from other disaster zones where his specialized volunteer team has responded.
