When investors think of Berkshire Hathaway (BRKA, Fortune 500), they of course think of Warren Buffett and his record as a hands-off, if highly attentive, CEO. He gives free rein to the heads of his large collection of companies, ranging from Geico to Dairy Queen to Benjamin Moore to the Buffalo News to NetJets. Yet even in Buffett's empire, sometimes a CEO blows it, and his business needs to be fixed or a deal needs to get done -- fast. When that happens, Buffett's go-to guy is David Sokol.
Of all Berkshire's lieutenants, Sokol, 53, is mentioned most often as Buffett's heir, although Sokol shrugs off such speculation. Buffett likes Sokol just where he is, getting deals done, boosting profits, and turning around ailing businesses. In the foreword to Sokol's book, Pleased but Not Satisfied, Buffett writes, "He brings the business equivalent of Ted Williams' .406 batting average to the field of business management."
