A graduate of the United States Military Academy at West Point, he began his career as an Army infantry officer before earning his medical degree and returning to service as an emergency physician. He later served as a flight surgeon with the Army's 160th Special Operations Aviation Regiment, the Night Stalkers, planning and flying some of the War on Terror's most covert operations across Afghanistan and Iraq.
On 13 December 2003 he participated in Operation Red Dawn, the mission that captured Saddam Hussein, and interrogated Saddam for six hours that night. He published the account as A Night with Saddam. For his service he was awarded the Bronze Star, the Air Medal with Valor Device and the Combat Medical Badge.
After two decades of military service he founded and built an emergency medicine management company that grew to more than $200 million in annual revenue, serving 52 hospitals across 11 states, before selling the business into a physician-services platform backed by Goldman Sachs. He also founded clinics providing free medical care to underserved communities.
He entered public service in 2012, serving in the Tennessee Senate before representing Tennessee's Seventh Congressional District in the United States House of Representatives from 2019 to 2025. As Chairman of the House Committee on Homeland Security he worked at the centre of national debates over cybersecurity, critical infrastructure, supply chains, border security and strategic competition with China.
At Bifrost he connects decisions made in Washington with their consequences across compute, power, infrastructure, critical materials and capital markets: understanding the entire system, identifying where its constraints are moving, and investing where national priority becomes economic reality.
