Great-West Financial on Wednesday named Edmund Murphy III as president of its retirement services organization, which includes its recently acquired operation in Overland Park.

Murphy, 52, will be based at Great-West’s Denver-area headquarters. He has worked in the retirement and asset management industries for more than 30 years, most recently as head of defined contributions at Putnam Investments.

Great-West last month completed the purchase of J.P. Morgan Retirement Plan Services, based on the Sprint campus. Great-West also recently added the retirement business of Putnam Investments.

The former JPMorgan operation earlier this year had about 1,000 employees, mostly based here.

The acquisition makes Great-West the second-largest recordkeeper of 401(k)-type retirement plans, with about 7 million participants and more than $400 billion in assets.
