San Fernando Valley Clinic Operator Sentenced to 18 Years in Federal Prison for Role in Ring that Sold Illegal Opioid Prescriptions for Cash

SANTA ANA, California - A San Fernando Valley man who operated corrupt medical clinics was sentenced today to 216 months in federal prison for participating in a drug trafficking ring that sold thousands of illegal opioid prescriptions for cash.

Justin Douglas Cozart, 48, of Woodland Hills, who operated and supervised the ChiroMed medical clinics, was sentenced by United States District Judge David O. Carter.

In February 2025, at the conclusion of a five-day trial, a federal jury found Cozart guilty of one count of conspiracy to distribute and to possess with intent to distribute oxycodone, one count of conspiracy to launder monetary instruments, and one count of concealment money laundering.

From 2017 to January 2020, Cozart and others knowingly and intentionally participated in a conspiracy to distribute the opioid painkiller oxycodone outside the usual course of professional practice and without a legitimate medical purpose.

Cozart operated several medical clinics in Southern California. Other members of the conspiracy recruited sham patients to go to Cozart's clinics - including ones in Inglewood, Santa Ana, and Anaheim - to obtain oxycodone prescriptions. Cozart employed doctors at the clinic, including John Korzelius, 74, a.k.a. "Dr. K," of Long Beach, who wrote oxycodone prescriptions for the fake patients. The recruiters then paid Cozart for the fraudulent oxycodone prescriptions.

Upon obtaining the prescriptions from the clinic, the recruiters took the sham patients to a pharmacy to fill the prescriptions. After collecting and consolidating the pills, co-conspirators shipped them to a drug customer in the Boston area, for distribution on the black market. On two occasions in October and December 2018, parcels containing their consolidated pills were seized by law enforcement.

In November and December of 2019, at a clinic in Inglewood, Korzelius issued prescriptions for 60 30 milligram oxycodone pills - the highest dose of short-acting oxycodone available and the dose most popular among drug abusers - to a patient who actually was an undercover law enforcement officer.

Korzelius did not conduct a physical examination of this "patient" and instructed the undercover officer to not fill the prescription at a large pharmacy such as Walmart or CVS.

"[Cozart] was a primary, illegal source of supply of oxycodone, a dangerous and frequently abused drug, for an organization that was shipping thousands of pills across the country for sale," prosecutors argued in a sentencing memorandum. "He converted otherwise lawful chiropractic clinics into drug trafficking businesses, and pulled their existing employees…into his scheme."

In total, prosecutors in this case have secured nine convictions.

Korzelius pleaded guilty in February 2025 to one count of conspiracy to distribute oxycodone. His California medical license expired in December 2020. His sentencing hearing is scheduled for June 8.

The Drug Enforcement Administration and IRS Criminal Investigation investigated this matter. The Department of Health and Human Services Office of Inspector General and the Torrance Police Department provided substantial assistance.

Assistant United States Attorneys Rosalind Wang and Brian Yang of the Orange County Office are prosecuting this case.
