Worthington dentist Mark Jerman pleaded guilty to five counts of illegally processing drug documents on Feb. 16 in Franklin County Common Pleas Court.

Judge Guy Reece placed Jerman on probation for two years and imposed a $500 fine. He is to undergo a 30-day inpatient treatment program as a term of his probation.

Jerman practices at 510 High St. in Worthington with his father, Steve Jerman. Mark Jerman, 45, lives in Upper Arlington.

From 2006 to 2010, he wrote prescriptions for painkillers that were filled by friends and co-workers. They delivered the pills to Jerman, who last week said he was addicted.

The prescriptions were for hydrocodone, also known as Vicodin.

Jerman continues to have a dental license, but that could be in jeopardy. The Ohio State Dental Board will consider his case at its April 11 meeting.

According to The Columbus Dispatch, Lili Reitz, the board’s executive director, said he could reach a settlement with the board that would include a license suspension while he undergoes treatment.
