Daniel Brown pleaded guilty last year to a single conspiracy charge and agreed to cooperate with the investigation.
He was sentenced by Judge Benita Pearson in federal court in Youngstown earlier this month.
Brown on Friday appealed the sentence to the 6th U.S. Circuit Court of Appeals in Cincinnati.
Brown’s attorney, Russell Bensing, said federal guidelines called for a sentence in the range of 2 ½ to 3 ½ years.
