Dr. Mark Ibsen, born in 1955, is a veteran ER physician with over 30 years of experience and six years in urgent care. After a 19-year legal battle with the Montana Board of Medicine-- winning 10 cases but losing his business and spending $750,000, he stopped prescribing opioids in 2017 due to a hostile regulatory climate. He resumed treating “pain refugees” at the request of former patients of Dr. David Bockoff, and now faces a nationwide boycott by Walgreens and Walmart, two more cases with the Montana BOME, and a federal subpoena set for July 23, 2025.
