Sukin was brought on as president over Texas Children’s Hospital in September 2023 and began working under Wallace to prepare as his successor in the role.
“I’ve spent a lot of time reflecting on when my last day would be since announcing the search for a new president last year,” Wallace said. “I knew back then that my final chapter was beginning, and I’m so happy with how everything has fallen into place."
Wallace announced his retirement would be effective Oct. 4 following 35 years as CEO; Sukin will officially assume the position on Oct. 5. Before joining Texas Children's, Sukin served as executive vice president over the Houston Methodist system and as CEO for Houston Methodist The Woodlands Hospital. Sukin also previously served as senior vice president of St. Luke’s Health System in the Texas Medical Center.
In their words
- “It has been an honor to work with Mark Wallace over this past year, and I want to thank him for his visionary leadership which has grown the world’s largest women’s and children’s hospital,” Sukin said. “I look forward to building upon Texas Children’s 70-year history of providing clinical excellence, teaching and research to those we serve across the globe and leading us into the future.”
- “As I embark on this new season—one filled with more time with my wife and my family, friends and perhaps even a few new adventures—I leave with a full heart and deep appreciation for my incredible team,” Wallace said.
- “Mark has been the heart and soul of Texas Children’s for decades and his departure, although very well-deserved, is truly bittersweet,” said Tym Tombar, vice chair of the Texas Children’s board of trustees. “I speak for the entire board when I express our sincerest gratitude to Mark for his 35 years of inspiring leadership and our utmost confidence in Debbie Sukin for her vision, business acumen and commitment to our mission.
Sukin will remain as acting president over Texas Children's Hospital, and will assume the full duties of CEO on Oct. 5.
