Ohio prosecutor Bill Mason will join Columbus-based Bricker & Eckler as a partner in its public finance group on October 1.

Mason, who has served Cuyahoga County prosecutor since 1999, will focus on public sector clients, including municipalities, school districts and counties. Cleveland is located in Cuyahoga County, the most heavily populated in Ohio.

“This is a natural transition for me,” Mason said in a press release. “Joining the public finance group at Bricker & Eckler allows me to continue serving the public in a different way.”

Mason, 53, prosecuted former stockbroker Frank Gruttadauria, who in 2004 was convicted of corruption and money laundering. His former employers, including Lehman Brothers and SG Cowen Securities Corp., paid the county about $10 million in prosecution costs.

Bricker & Eckler partner Glenn Krassen said that Mason’s “hands-on experience” as chief of the prosecutor’s office would help the law firm’s public sector clients meet their financial challenges.

Bricker & Eckler, with 140 attorneys, was founded in 1945 by John Bricker, a former Ohio governor and U.S. senator.
