Jack Byrne to succeed Clements as Integro board chairman

John (Jack) Byrne has been elected chairman of the board of Integro, succeeding Integro’s co-founder and chairman, the late Robert Clements.Early in his career, Byrne joined Travelers Insurance Company, and subsequently burnished his reputation with the turnaround of a struggling GEICO, which he joined as CEO in 1976. A rags to riches story, GEICO was subsequently sold to Warren Buffett. Byrne and Buffett then worked together at the Fireman’s Fund, which was the largest IPO of its time. Byrne continued to lead White Mountains Insurance Group, a financial services holding company, after the sale of its Fireman’s Fund division to Allianz of Germany in 1990.
