Fabian Dori, who is head of offering, portfolio management and advisory at Notenstein La Roche, will be leaving the bank in the third quarter of 2017.
According to a spokesperson at the firm, the bank is streamlining its organisation, revising product offerings and introducing a new core banking system in 2017, which results in personnel changes.
Dori has been working at the bank since October 2016, when he joined as head of the investment house.
Prior to that he was head of portfolio management at 1741 Asset Management.
The departure of Dori comes five months after Silvan Schriber, head of Zurich operations, left the bank.
Schriber joined the management team at Additiv, a provider of digitalisation for banks and asset managers.
Both were managed by Citywire A-rated CIO Matthias Geissbühler, who is still in charge of the Notenstein La Roche CH Mid-Small-Index Active Plus and the Notenstein La Roche Asia Opportunity funds.
