What Happened
Dr. Jonathan S. Clark, D.O., of Poteau, Oklahoma, agreed in December 2025 to pay $105,000 to settle allegations that he violated the Controlled Substances Act. The United States alleged that he ordered controlled substances outside the course of professional practice, stored and dispensed controlled substances at an unregistered location, and failed to maintain records showing the dates substances were received and dispensed. The settlement resulted from a DEA Diversion investigation that determined misuse and improper storage of controlled substances and incomplete records. The claims resolved by the settlement are allegations only, with no determination of liability.
“stored and dispensed controlled substances at an unregistered location, and failed to maintain records containing the dates that substances were received and dispensed”
