Joe Lewis’ $8 Billion Empire Loses Top Executive in Power Shift

The top executive at Joe Lewis’ investment firm has left after working for the UK billionaire for more than two decades, leaving a younger crop of leaders atop the currency trader’s global empire.

Shehan Dissanayake departed Tavistock Group for personal reasons after most recently serving as the firm’s chairman, according to a person with knowledge of the matter. The 58-year-old Sri Lankan native, who still appeared on Tavistock’s website in late 2024, is also no longer based in the US, said the person, who asked not to be identified as the details are private.
