Cincinnati-based Dinsmore & Shohl has announced a merger with the litigation boutique of Dick Cheney’s former lawyer in San Diego, California. The San Diego office is the firm’s first on the west coast.

Founded in 2012 by  Joe Leventhal , Leventhal Law has four attorneys altogether and brings Dinsmore’s total to 625 in 21 cities. Leventhal’s practice is focused on complex commercial litigation. Previously, he served in the White House as Deputy Assistant to Vice President Cheney.

Leventhal, who worked with Cheney’s senior staff until 2004, when he joined Cooley LLP before starting his own firm, said that Dinsmore was an attractive destination because it allowed his team to bill “reasonable rates.”

Dinsmore Managing Partner and Chairman George Vincent said his firm has several clients in California, and firm leaders have been wanting for some time to add lawyers in the area.

According to Vincent, Matthew Wiles, an attorney in Dinsmore’s Columbus office who had previously practiced in California, first brought Leventhal to the firm’s attention. Vincent said Leventhal met with Dinsmore’s board about two months ago and “it moved pretty quickly after that.”

The merger is Dinsmore’s  third this year : the firm picked up West Virginia-based Huddelston Bolen LLP in February, and in September merged with Detroit-based intellectual property boutique Gifford, Krass, Sprinkle, Anderson & Citkowski.

In addition to California, Dinsmore has offices in Colorado, Connecticut, Illinois, Kentucky, Michigan, Ohio, Pennsylvania, Washington, D.C., and West Virginia. In 2014, the firm grossed more than $195 million in revenue, 148th on the 2015 Am Law 200 rankings.
