National law firm Wilson, Elser, Moskowitz, Edelman & Dicker has opened an office in Hartford, its second location in the state. Officials said a state government lobbying practice will be one of the focal points of the new office.

The firm moved into the Connecticut market by opening a Stamford office in 2004 with just a handful of attorneys. That number has grown to 20, officials said last summer, with insurance defense and lobbying being particularly strong practice areas. At the time, the firm said it would consider further growth in the state.

The new office officially opened Jan. 2.

“A growing Connecticut-based Government Affairs practice led by partner David Rose and a response to client demand were the impetus for opening the Hartford office,” Brian Del Gatto, managing partner of the Connecticut region, said in a prepared statement. “Though we’ve always serviced the entire state from our Stamford and Boston offices, an office in Hartford puts us in the epicenter of the insurance industry and in proximity to our clients throughout New England.”

Wilson Elser was No. 105, with gross revenues of $293 million in 2012, according to the latest Am Law 200 survey of law firms by the American Lawyer, an affiliate of the Connecituct Law Tribune. The firm says it now has nearly 800 lawyers in 25 offices in the U.S. and one in London.

Rose joined the firm in February 2011, at a time when Wilson Elser expanded its Government Affairs practice beyond New York. Rose has previously served as senior counsel for two Connecticut speakers of the house and assistant counsel for three New York governors.

“David has been extremely effective at monitoring legislative and regulatory developments for our clients, as well as protecting or advancing their interests throughout Connecticut government,” Del Gatto said.

The Government Affairs practice serves a diverse array of clients, advising them on public policy, legislation, regulation, procurement and appropriations before the Connecticut General Assembly and executive branch. In addition to Government Affairs, attorneys in the Hartford office will offer a full complement of other legal services.

Del Gatto specifically cited partner Stephen Brown, who heads up the firm’s Connecticut-based litigation practice and Eric Niederer, whose practice focuses on health care issues.
