Susan Oh will join Janus Capital Group as senior vice president of its U.S. institutional group, effective Oct. 3.
She will oversee Janus' centralized institutional sales and marketing teams, according to a Janus spokeswoman.
Ms. Oh replaces Daniel P. Charles, who left in early 2010 to become global head of distribution for William Blair Investment Management.
Ms. Oh will come to Janus from J.P. Morgan Asset Management, where she served as the firm's global consultant strategy sales leader and group head for the Americas consultant sales team.
J.P. Morgan spokeswoman Kristen Chambers said the position will be filled; no other details could be learned by press time.
