A transition team will be formed, and Texas Health will begin the search for a new president.

“Mark has been a key contributor to the Texas Health system for more than 14 years,” said Steve Hanson, senior executive vice president for system alignment and performance at Texas Health. “Mark has accomplished great things at Texas Health — he’s been the executive champion for rolling out the electronic health record across the system, and he has led the expansion of our Dallas hospital that will culminate in the opening of the new Hamon Tower in just a few months. It’s a testament not only to Mark’s abilities but also to the high-caliber of leadership within the Texas Health system that others across the country look within our ranks for their future leaders.”

Gary Hutchison, M.D., chairman of the board of Texas Health Presbyterian Hospital Dallas, said, "Presbyterian Hospital staff and patients are indebted to Mark Merrill for his years of service. We are sorry he is leaving. We wish the best for him and his family and for his professional life."

“This next step in my career affords me two opportunities I couldn’t refuse,” said Merrill, “the chance to serve as chief executive officer of a highly-respected multi-hospital system and the honor of returning to live closer to my wife Teri’s family and my family. The past 14 years with Texas Health Dallas and Texas Health Resources have been rich with experiences and growth. Rising to the top of my blessings are the relationships I’ve built within our hospitals and the community. It’s hard to imagine a finer group of employees, physicians, volunteers and trustees than those I’ve encountered at Texas Health Dallas and THR.”

Merrill joined Presbyterian Healthcare System in January 1995 as president of the Dallas hospital. Named an executive vice president of Texas Health in 2005, he has served in many system leadership roles, including co-chairman of the system’s Electronic Health Record Implementation Committee. During his tenure, he led the team at Texas Health Dallas in accomplishing significant advances in several clinical programs and helped position the hospital as a health care destination, attracting patients from across the nation.
