PITTSBURGH — A cardiologist who pleaded guilty to illegally dispensing drugs while serving as the medical director of a methadone clinic raided by federal agents is due to be sentenced by a federal judge in Pittsburgh.

Sixty-nine-year-old Dr. Dominic DiLeo, of Uniontown, pleaded guilty last year to conspiring to illegally distribute Suboxone at the clinic run by Rosalind Sugarmann. The Allison Park woman was sentenced to a year in prison last week for her role in the scheme at her Addiction Specialists clinic in Fayette County. DiLeo also pleaded guilty to illegally prescribing the anti-anxiety drug Xanax.

DiLeo was sentenced to 10 years in prison for Medicare fraud in the 1990s. He also lost his medical license, but it was reinstated in 2005. In that case, he wrote illegal painkiller prescriptions and took kickbacks that he spent on extramarital affairs.
