Hart, who also is assuming the title executive vice president, is taking the legal reins after serving as deputy chief legal counsel since 2020. He joined Liberty Mutual in 2014 after serving as a partner at three national law firms—Littler Mendelson, Ogletree Deakins and Holland and Knight—where he focused on litigation and employment matters.
