Mayor John Cooper announced Friday that Metro Law Director Bob Cooper will soon step down from his post and be succeeded by Nashville attorney Wally Dietz.

Dietz practices at Nashville law firm Bass Berry & Sims — to which Bob Cooper will return for private practice upon departure from office in early June. Dietz chairs Bass' compliance and government investigations practice group and focuses on international anti-corruption and corporate governance litigation. He brings nearly four decades of experience in law to the job.
