Warner Thomas, President and Chief Operating Officer of Ochsner Health System, became the system’s President and Chief Executive Officer on September 1. Thomas succeeds Dr. Patrick Quinlan, who has led Ochsner Health System since 2001.

Since the Quinlan-to-Thomas transition was announced in May, Thomas has been on an Ochsner “listening tour” of 40 small meetings with a broad spectrum of people from across the organization. More than 200 leaders, employees, and physicians have participated in the 90- to 120-minute meetings focused on what is working well in the organization, what can be improved, employee/ physician engagement and transparency.

“The listening tour provided valuable insights into the state of Ochsner Health System which, along with my 14 years of experience with this organization, further formed our plans for the future,” Thomas said. “The healthcare industry is facing challenging times, but Ochsner is well prepared to not only survive but to take the responsibility of local and regional leadership seriously. Together, we will continue on the path to being counted among the nation’s very best caregivers.”

Today, Thomas announced leadership appointments designed to support his vision for the future:

  • Patrick Quinlan, MD, who has served as Ochsner’s CEO for 11 years, will become CEO,

Ochsner Clinic Foundation and Ochsner International Services and Executive Director, Center for Community Wellness and Health Policy. The International Services department will focus on international business partnerships.

  • William Pinsky, MD, who is currently Executive Vice President and Chief Academic Officer, Ochsner Health System, will continue in that position and also serve as Executive Vice President, Clinical Affairs for International Business.
  • Richard Milani, MD, FACC, FAHA, who is currently Vice Chairman, Department of Cardiology, will serve as Chief Clinical Transformation Officer, Ochsner Health System.
  • Michael Hulefeld, who is currently CEO, Ochsner Medical Center and New Orleans Region, will now serve as Executive Vice President and Chief Operating Officer, Ochsner Health System.

  • Diedra Dias, who was Manager of Strategic Operations, will manage key strategic initiatives as

Director, Office of Strategy Management.

A national search for an Ochsner Chief Development Officer is underway.

“During Hurricane Isaac, I was continually reminded what an amazing team of physicians, nurses and professionals we have at Ochsner,” said Thomas. “I am honored to work with them as we continue to define the future of excellent medical care in the Gulf South.”

As president and chief operating officer, Thomas led Ochsner’s effort to build its own hospital system through the acquisition of six hospitals, which led to the Ochsner Health System as it stands today serving people across Louisiana and the Greater Gulf South.
