Each was convicted of one count of conspiracy and six counts of taking bribes. The pair was accused of taking kickbacks in exchange for patient referrals between the facility and Borrasi's Romeoville office, federal officials said.
Sentencing is set for Oct. 6.
Mamoon, Borassi and Mahmood Baig, Rock Creek's former director of operations, were indicted in January of 2007. Baig, 58, of Bolingbrook, pleaded guilty to participating in the conspiracy and testified at the trial of his co-defendants, the U.S. Attorney's Office said. Federal officials say the scheme netted $565,000 in kickbacks over approximately three years.
Mamoon and Borrasi each face a maximum penalty of five years in prison and a $250,000 fine for each of the seven counts of which they were convicted.
