Sherman doctor pleads guilty to federal drug charges

Howard Gregg Diamond

SHERMAN, Tex. (KXII) - Federal prosecutors announced Friday a Sherman doctor has pleaded guilty to federal drug distribution and fraud violations.

Howard Gregg Diamond, 57, agreed to a sentence of 20 years in federal prison, waived his right to appeal and forfeited his DEA registration number at a plea hearing this week.

Diamond operated pain management centers in Sherman and Paris.

According to information presented in court, beginning in 2010, Diamond wrote prescriptions for substances such as hydrocodone, oxymorphine, methadone, fentanyl, morphine, oxycodone, alprazolam, and zolpidem, without a legitimate medical purpose.

Specifically, in July 2014, Diamond distributed or dispensed morphine, oxycodone, alprazolam and zolpidem to an individual that resulted in that individual’s death later that month. Additionally, Diamond had a claim for reimbursement for services submitted to Medicare claiming he treated a Medicare patient in, 2015, although he was in another state at that time. Diamond was indicted by a federal grand jury last summer.

"Physicians like Dr. Diamond have been fueling the opioid crisis in this country," said U.S. Attorney Joseph D. Brown. "The number of pills that he was putting out on the street was shocking. And in this case, death was linked to those pills. Undoubtedly, others' addictions were worsened, and families suffered as a result. To reduce the impact of opioids, doctors have to take their obligations seriously, and if they don't, there will be more prosecutions like this."

A sentencing hearing will be scheduled after the completion of a pre-sentence investigation by the U.S. Probation Office, Brown said.
