Damon Vocke, a former president and general counsel at Berkshire Hathaway Inc. reinsurance subsidiary General Re Corp., announced Wednesday that he would form his own boutique. Four other lawyers are joining Vocke as partners at his new firm, which will have offices in three cities.

The Vocke Law Group will be led by its namesake and his longtime colleagues Cynthia Bordelon, Ronald Lepinskas, Scott Ostericher and Tomas Thompson. The new firm will directly target reinsurance and insurance companies and have offices in Chicago, New York and Stamford, Connecticut.
