"As the first medical director and attending psychiatrist at the World Trade Center Mental Health Program, Dr. Sue Varma worked directly with civilian and first-responder survivors in the aftermath of 9/11. There, she met people at every point of the stress and trauma continuum. She saw devastation and stagnancy as much as she saw amazing resilience and growth. She asked herself: how do some people survive, even thrive, despite profound challenges? And how can we optimize the things we have control over, while buffering ourselves from stress?
