Worthington – Quintain’s finance director until her promotion in May – will leave the company on 31 October. Some of her duties will go to Richard Stearn, who was hired from the Berkeley Group in January.
Anthony Gill will take over Worthington’s responsibilities for the Greenwich Peninsula project after recently being appointed development director.
“The time is now right to realise my long-held ambition of running my own business,” Worthington said without disclosing details of her new venture.
Quintain has seen a complete shake-up of its management team over the past year. Chief executive Adrian Wyatt left in May, 20 years after founding the firm.
The regeneration specialist is developing 85 acres of land around Wembley Stadium and also recently secured the backing of Hong Kong-based investment group Knight Dragon for its 150-acre Greenwich Peninsula scheme.
