MANCHESTER — Elliot Health System’s new chief operating officer is no stranger.

Joseph Tate Curti, most recently COO of Southern New Hampshire Health, has been leading efforts of bringing the two health care systems into a new regional health care organization, SolutioNHealth. Both hospitals, however, are retaining their separating identities.

“As chief operating officer, Tate will be responsible for Elliot Hospital operations, as well as oversight of the Elliot Medical Group,” both primary care and specialists, and the Visiting Nurses Association of Manchester & Southern New Hampshire,” Elliot said in its announcement Thursday.

At Southern New Hampshire Health, Curti had oversight of hospital operations at Southern New Hampshire Medical Center, including direct involvement in strategic planning, clinical excellence initiatives, and patient experience and advocacy efforts.

Curti previously was part of Elliot Health System’s senior team, serving as vice president of professional and support services.

Curti, a fellow of the American College of Healthcare Executives, will start his new role Feb. 11.
