Early life and educationEdit

Chiarelli was born in Seattle, Washington, on March 23, 1950, and graduated from Queen Anne High School in 1968.[1] He is a Distinguished Military Graduate of Seattle University Army Reserve Officers' Training Corps. Chiarelli was commissioned a second lieutenant in September 1972. Throughout his career, he has served in army units in the United States, Germany, and Belgium. He has commanded at every level from platoon to corps.

Military careerEdit

Chiarelli's first assignments were with the 9th Infantry Division at Fort Lewis, including: support platoon leader for 3rd Squadron (Air), 5th Cavalry Regiment; squadron assistant intelligence staff officer (S-2); squadron intelligence staff officer (S-2); troop executive officer; and troop commander.[3]

Chiarelli's principal staff assignments were Operations Officer (G-3), 1st Cavalry Division, at Fort Hood, Texas; Executive Assistant and, later, Executive Officer to the Supreme Allied Commander, Commander United States European Command at SHAPE Headquarters, Mons, Belgium; and the Director of Operations, Readiness, and Mobilization (G-3/5/7) at Headquarters, Department of the Army.

Chiarelli commanded a motorized infantry battalion, 2nd Battalion, 1st Infantry Regiment, and the 199th Infantry Brigade, a separate motorized brigade at Fort Lewis, Washington; served as the assistant division commander for support in the 1st Cavalry Division at Fort Hood, Texas; served as commanding general, 1st Cavalry Division, and led it both in the Iraq War and during Operation Iraqi Freedom II; and served as commanding general of Multi-National Corps – Iraq from January 2006.[4]

Chiarelli holds a Bachelor of Science degree in political science from Seattle University, a Master of Public Administration degree from the Daniel J. Evans School of Public Affairs at the University of Washington, and a Master of Arts degree in national security strategy from Salve Regina University. He is also a graduate of the U.S. Naval Command and Staff College and the National War College.

Chiarelli worked to reduce suicide rates in the army. Out of concerns for stigma, he began using the term "posttraumatic stress", dropping the word "disorder" from the medical name posttraumatic stress disorder. His term had subsequently become standard use in the armed forces, but was not taken up by the medical community. The name "posttraumatic stress injury" has been proposed by some psychiatrists in 2012, and is endorsed by Chiarelli.[5]

Chiarelli is currently CEO of One Mind, which is dedicated to benefiting all affected by brain illness and injury through fostering fundamental changes – using open science principles and creating global public-private partnerships among governmental, corporate, scientific and philanthropic communities – that will radically accelerate the development and implementation of improved diagnostics, treatments and cures – while eliminating the stigma that comes with mental illness.[6]
