UK - London-based asset manager, Gartmore has hired Marek Siwicki from Aon Consulting.

Siwicki, a highly regarded senior consultant, will join Gartmore to work in consultant relations.

Gartmore underwent a lengthy period of rumour and process of sale which ended last year with its acquistion from Nationwide Mutual by Hellman & Friedman.

Shamus Young, global head of consultant relations, ended up leaving for a similar role at ABN Amro Asset Management while his deputy, Paul Hamilton, moved to BlackRock.

Siwicki worked at Aon since 1999.
