K. L. Sadler is a retired U.S. diplomat, former Supervisory Special Agent with the U.S. Department of State’s Diplomatic Security Service, and author of From the Badge to the Vine: A Journey Through Duty, Trauma, and Healing. Over a 26-year career in law enforcement and international security, she served in high-threat assignments across Iraq, Afghanistan, Uganda, Mexico, and El Salvador.
Her memoir explores moral injury, grief, identity, psychedelics, spirituality, and the long process of healing after a life shaped by duty and control. Her work has been featured in the MAPS Bulletin.
In 2026, Sadler walked 780 kilometers across Spain on the Camino de Santiago with her dog, Nona.
Today, her work centers on a simple message: healing is possible, there are many paths to healing, and the first step is often recognizing the need to heal—then finding the path that is right for you.
