Stony Brook Eastern Long Island Hospital Appoints Annalisa Monahan CNO and SVP

Stony Brook Eastern Long Island Hospital announced on February 20, 2026 that Annalisa Monahan, DNP, MHA, MSN, RN-BC, NE-BC, has been appointed Chief Nursing Officer (CNO) and Senior Vice President of Patient Care Services, with the appointment taking effect February 9, 2026. The hospital identified Monahan by the credential string recorded in the announcement.

A separate Stony Brook Medicine leadership roster lists Monahan with a slightly different credential order - "DNP, MSN, MHA, NE-BA" - creating a noted variation in the certification abbreviation. The original announcement explicitly included RN-BC and NE-BC in Monahan’s credentials; the roster entry preserved the NE-BA spelling as an alternate form in system directories.

Monahan’s appointment places her within a leadership team that includes Alison Madden, MD, listed as Senior Vice President Medical Affairs and Chief Medical Officer for SBELIH, and Paul J. Connor, III, identified on the roster as Chief Administrative Officer. Other executive names on the SBELIH leadership list include William J. Messner as Senior Vice President Finance, Susan Apicello as Vice President Administration and Director of Laboratory Services, and Carrie Grattan, BSN, RN, as Senior Director of Nursing Operations, Patient Care Services. The published "Medical Staff Officers 2026" roster names Lawrence R. Schiff, MD, as Chair of the SBELIH Leadership Coordinating Council and Abida Butler, MD, as Vice Chair.

The materials provided also link SBELIH to the Stony Brook Medicine network and include directory-style data showing a Stony Brook Medicine headquarters address at 201 Manor Pl, Greenport, New York 11944 and a contact phone number of (585) 335-5200. Corporate metadata in the directory lists Stony Brook Medicine revenue at $2.8 billion, 13,500 employees, and a founding year of 2010; image captions in the directory include "Image 92: Deborah Overton Annalisa Monahan Chief Nursing Officer."

The announcement and roster fragments did not include a professional biography or prior positions for Monahan, nor did they include any direct quotes from Monahan or other SBELIH executives. The hospital’s publicized materials supplied the effective date of February 9, 2026 and the announcement date of February 20, 2026, but did not describe operational duties, reporting changes, bed counts, patient volumes, or strategic priorities tied to the CNO and Senior Vice President Patient Care Services roles.

Monahan’s appointment becomes part of SBELIH’s 2026 leadership slate as the hospital integrates nursing and patient care oversight under the title Senior Vice President Patient Care Services, joining Alison Madden, Paul J. Connor, III, and the other named directors and vice service chiefs listed in the SBELIH leadership roster.
