Memorial Hermann Health System has named Bryan Sisk as its new senior vice president and chief nursing executive, officials announced in a May 23 news release.

Sisk, who has more than 20 years of experience in nursing and health care leadership, will work with staff throughout Memorial Hermann’s network of health care facilities to improve patient and organizational outcomes as well as to develop career pathways to prepare, support and empower nursing leadership.

“Bryan brings an ideal set of skills to this role,” said Dr. David L. Callender, president and CEO of Memorial Hermann Health System, in a statement. “[He] has a strong understanding of what nurses are experiencing on the frontlines, and he creates environments where nurses and health care teams thrive.”

Sisk, a 20-year veteran of the Army, previously served in several leadership roles, including stints as chief nurse executive at Central Texas Veterans Health Care System in Temple and HCA Healthcare’s TriStar Division network in Tennessee.

“I’m incredibly honored to take on the role of Memorial Hermann’s chief nurse executive,” Sisk said in a statement. “With this role, I believe Memorial Hermann is demonstrating its commitment to nurses. I am here so we can continue the work of investing in our people, developing strong nurse leaders and creating systems that streamline care delivery.”


Memorial Hermann Health System is the largest nonprofit health system in southeast Texas, consisting of 17 hospitals, eight cancer centers, three heart and vascular Institutes, and 27 sports medicine and rehabilitation centers, officials said.

As previously reported by Community Impact Newspaper, the health care network opened a $250 million expansion of its campus in The Woodlands and also broke ground on a new sports medicine complex in Pearland in May.
