High-profile UK-based wealth management head hunter Harry Pilkington has resigned from Armstrong International. Mr Pilkington is believed to be joining international head hunter Heidrick & Struggles to strengthen its wealth management offering in its London office. Mr Pilkington, who is believed to have had a significant equity stake in Armstrong, joins several ex-Armstrong colleagues who have joined Heidrick’s financial services practice recently. WealthBriefing was not able to determine when Mr Pilkington will join his new firm but a commentator said that a period of six months gardening leave and another three months “hands off” would be appropriate.
