Former Delaware Attorney General Matt Denn has joined DLA Piper as a partner in the firm’s Wilmington office, where he plans to represent clients in litigation involving state attorneys general, insurance regulators and other state agencies.

Denn’s return to private practice follows his 14 years in public service, which included stints as insurance commissioner, lieutenant governor and one term as the state’s top law-enforcement official. Denn, who championed criminal justice reform and took on the opioid crisis as attorney general, did not pursue a second term as the head of the head of the Delaware Department of Justice and officially left office earlier this month.
