A Georgetown-based interior decorator is scheduled to plead guilty Monday to committing fraud to obtain a $1.3 million federal contract to decorate the new Immigration and Customs Enforcement headquarters in Southwest Washington. Darlene Mathis-Gardner is accused of faking invoices to show that her firm had performed similar renovation projects, and claiming that employees had security clearances and professional certifications when they did not. Mathis-Gardner, president and founder of Systems Design Inc., faces up to five years in prison and a $250,000 fine.

Mathis-Gardner’s company has secured $9.6 million in government contracts since 2001, with two-thirds of that amount being awarded no-bid, according to Opensecrets.org. That doesn’t include a $5.4 million contract that was awarded last year to design custom crystal stemware for the State Department even though her company didn’t have any glassmaking experience.
