Irvine-based St. Joseph Health said today that Kevin Manemann is the new chief executive of its St. Joseph Heritage Healthcare physician practice management organization.

Manemann succeeds C.R. Burke, who retired at the end of December.

He most recently served as chief operating officer for Heritage’s Southern California region.

Manemann also is in charge of the population health division of Irvine-based St. Joseph Hoag Health, the integrated regional delivery network created by St. Joseph Health and Hoag Memorial Hospital Presbyterian.

Heritage is made up of eight medical groups and five affiliated physician networks with more than 2,200 doctors.
