Acacia Insurance has appointed insurance lawyer Mark Williams as an executive director.

Mr Williams founded the insurance law arm of Landers & Rogers in Sydney in 2002, specialising in professional indemnity, directors’ and officers’ insurance and general liability.

He was involved in Australian Securities and Investments Commission investigations following the collapses of Great Southern, Allco and Hastie.

He will provide key insights and advice to clients around risk and exposure, Acacia says.
