Sally Manion will step down as the head of financial planning at ipac after nine years with the financial services company.
As yet there is no replacement for Manion, but ipac chief executive Neil Swindells said he was interviewing a number of people for the role.
Manion will be on board until February, at which point she will be taking a break.
According to Swindells, Manion made the decision to leave ipac following the merging of ipac financial planning and ipac business partnering.
This announcement comes on the back of the December 2009 departure of ipac head of business partnering John Saint, who left to take up the position of chief executive of Axa-owned dealer group Genesys.
Ipac chief operating officer Eric Gibson is acting head of business partnering until a permanent replacement is found.
Swindells said Manion's departure was on good terms.
"She has a lot to keep her busy until February and will leave the business in good shape," he said.
