Chief Executive Officer

Mark A. Wallace was appointed President and Chief Executive Officer of Texas Children’s Hospital in 1989 at the age of 36. Under his leadership, Texas Children’s has grown into one of the nation’s largest and most comprehensive pediatric and women’s health care organizations, recording nearly 4.6 million patient encounters annually and achieving international recognition as a referral center. U.S. News & World Report consistently ranks Texas Children’s Hospital in the top five among all children’s hospitals in the nation.

During Mr. Wallace’s 30-year tenure, he has led Texas Children’s successful completion of numerous capital and expansion projects that have resulted in the addition of over 5 million square feet of space to its Texas Medical Center campus, along with two community hospitals—Texas Children’s Hospital West Campus and Texas Children’s Hospital The Woodlands—representing a significant investment in the future of pediatric health care.

Most recently, Texas Children’s completed Promise: The Campaign for Texas Children’s Hospital, to ensure that the hospital continues to evolve to meet the needs of a growing patient population who have a wider spectrum of complex needs and who come from all over the world in search of specialized treatment and compassionate care. The campaign included construction of Texas Children’s Hospital The Woodlands, which provides the highest quality pediatric care close to home for families in the growing communities north of Houston, as well as construction of the Lester and Sue Smith Legacy Tower at the hospital’s Texas Medical Center Campus. This new building houses additional surgical and critical care services and is home to Texas Children’s Heart Center.

Prior to joining Texas Children’s Hospital, Mr. Wallace was a senior vice president at The Methodist Hospital in Houston. Mr. Wallace also holds the distinction of being one of the few executives in the country who advanced to fellowship status in the American College of Healthcare Executives (ACHE) at the age of 35. He has served twice as president of the ACHE Houston chapter.

Mr. Wallace holds degrees from Oklahoma Baptist University and Washington University in St. Louis. He is married to Shannon Baronette Wallace and they have two children, five grandsons and one granddaughter.
