Sonnenschein Dallas open for business

Chicago-headquartered Sonnenschein Nath & Rosenthal has launched a new office in Dallas, Texas.

The office will be led by Matthew Orwig, US attorney for the Eastern District of Texas, who will join the firm on 1 June 2007 to serve as Dallas managing partner and national chair of Sonnenschein’s government litigation and investigations group, as first revealed on www.the (10 April).

Joining him as partners are Matthew Yarbrough, who is leaving his role as head of the cyberlaw practice at Boston-based IP specialist Fish & Richardson, and employment lawyer David Cowart, who joins from Texas firm Jenkens & Gilchrist, which collapsed last month.

The Dallas office will focus on IP litigation, government litigation and investigations, healthcare compliance and the Employee Retirement Income Security Act, a US law on pension rights.

Orwig said: “We anticipate adding other extremely talented attorneys soon and aggressively expanding our capabilities.”

Orwig joined the Department of Justice as an assistant US attorney in 1989 and was appointed US attorney for the Eastern District of Texas in 2001.

During his tenure he served on subcommittees of the attorney-general’s advisory committee, including the white-collar fraud subcommittee and the healthcare fraud working group.

The Texas opening comes just a week after the official opening of Sonnenschein’s new office in Silicon Valley, which the firm has been setting up since late January (The Lawyer, 26 January).

But as revealed on www. (4 April), the California base was hit by a raid from Boston-headquartered Mintz Levin Cohn Ferris Glovsky and Popeo just a day after opening.

Corporate partners Matt Kirmayer and Jason Altieri have jumped ship to Mintz Levin’s Palo Alto office after spending three months setting up Sonnenschein’s Silicon Valley offering.
