March 13 (Reuters) - Cigna ( CI ) has made a series of

upper management changes, which include making CFO Brian Evanko

as the healthcare conglomerate's chief operating officer, and

promoting his deputy Ann Dennison to the top finance role.

Evanko, who has been CFO since 2021, will take over as

Cigna's ( CI ) president and chief operating officer from the end of

March, the company said on Thursday.

His successor, Dennison, joined Cigna ( CI ) last year, before

which she was CFO at Nasdaq.

Another executive, Eric Palmer, who was CEO of the company's

Evenorth Health Services business, will depart from the company

at the end of April after a 25-year tenure, Cigna ( CI ) said.
