Thomas J. Serena will retire as chief executive officer of AGA effective Dec. 31, 2026, ending a career of more than 30 years with the society.
AGA said it has retained the executive search firm Spencer Stuart to lead the search for his successor.
Mr. Serena's tenure spanned AGA's evolution from a professional society focused primarily on scientific exchange into an organization with a broader footprint in advocacy, governance, and product innovation. AGA credited him with strengthening its financial position while investing in new programs and growth opportunities, modernizing its practice strategy, and positioning the society as a home for innovation in gastroenterology.
“Tom's impact on AGA is difficult to overstate. His strategic vision, thoughtful leadership, and unwavering commitment to our mission have shaped the organization for generations of members,” said AGA President Byron Cryer, MD, AGAF. “Under his leadership, AGA expanded our influence, strengthened our foundation, and embraced innovation in ways that will benefit the field for years to come.”
Lawrence Kim, MD, AGAF, a past president of AGA, pointed to Mr. Serena's working relationship with the society's physician leaders across multiple administrations.
“He possesses a rare ability to balance long-term strategy with day-to-day execution while always keeping AGA's mission at the center of every decision,” Dr. Kim said. “His leadership has helped position AGA as one of the most respected medical societies in health care.”
In a statement, Mr. Serena said the role had been “the honor of a lifetime.”
“I have had the privilege of working alongside extraordinary volunteer leaders, dedicated staff, and countless members who are advancing the field and improving patient care every day,” he said. “Together, we have built an organization that is financially strong, innovative, and well-positioned for the future.”
