FOX 4’s Shaun Rabb got personal with DFR Medical Director Dr. Marshall Isaacs about his tattoos. They mark his journey of overcoming and finding hope. He now hopes his tattoos will lead others to make a decision that could save their lives. The role of the medical director for Dallas Fire-Rescue is to support paramedics, firefighters and officers in providing the highest quality emergency medical services to the people of Dallas when they call 911. The Highland Hills Apartments explosion was a mayday moment for Dr. Isaacs and DFR. Civilians and four firefighters were hurt. "I was most concerned with how badly injured our firefighters were," he said.
