Matthew A. Jacober

Matthew is a leading litigator and partner in Lathrop GPM’s Litigation & Dispute Resolution Practice Group, who works hand-in-hand with clients to help them realize their dreams and protect their assets. The son of a restaurant franchisee who grew up working in the family business, Matthew brings his first-hand knowledge of the risks and rewards of business to his representation of public and privately held corporations, individuals and organizations in a broad range of industries.

Matthew represents clients in class action defenses, fiduciary litigation, shareholder disputes for closely held corporations, government investigations (including federal, state and municipal criminal and civil investigations), qui tam defense, general business disputes and representation of property owners in condemnation proceedings. Matthew is also a Missouri state court-approved mediator.

Earlier in his career, Matthew served as a Special Assistant Attorney General for the State of Illinois, where he was assigned to the Illinois Department of Transportation and prosecuted condemnation matters on behalf of the State of Illinois. He also worked for the Illinois Criminal Justice Panel.

Matthew uses his powers for good by working pro bono to help wrongfully convicted men and women. He led the Lathrop GPM team that achieved the release of Laquanda Faye Jacobs after 26 years in prison for a murder she did not commit and, thanks in part to Lathrop GPM’s partnership with the Midwest Innocence Project, continues to work on behalf of other wrongfully convicted individuals. 

When Matthew steps away from work, he most enjoys time with his family, bird hunting with friends, and smoking ribs in his Big Green Egg.
