Houston Methodist receives $25M gift, renames department of medicine

med funding

Houston-based nonprofit The Duncan Fund has awarded a $25 million gift to Houston Methodist's department of medicine to establish new endowed fellowships, streamline complex care and bring artificial intelligence into the fold to develop more personalized treatment plans.

In turn, the health care system announced that it will rename the department the Charles W. Duncan Jr. Department of Medicine at Houston Methodist.

“We are deeply appreciative of the Duncan family’s support, which allows us to further programs at the intersection of personalized medicine and preventive health care to benefit our patients,” Dr. Eleftherios Mylonakis, chair of the department and the Charles and Anne Duncan Presidential Distinguished Chair, said in a news release.

The department of medicine is Houston Methodist's largest, and comprises 13 clinical programs, ranging from general medicine to highly specialized care, as well as research and education.

According to Houston Methodist, the latest grant from the Duncan family will:
  • Coordinate complex, multidisciplinary care by hospitalists
  • Implement programs that leverage data and AI to tailor treatments and preventive strategies
  • Establish five endowed fellowships, including a new fellowship for students known as MedTech Innovator

“Our vision is to redefine how care is delivered in our country by creating a national model for true continuity — one that follows the patient across every transition, from home to hospital and back again,” Mylonakis added in the release. “We are also advancing a deeper understanding of health span, shifting from reactive treatment to a proactive, lifelong strategy that maximizes not just how long we live but how well we live.”

The Duncan family has been a longtime supporter of Houston Methodist—and Houston organizations at large. The late Charles Duncan Jr. sat on the system's board for decades, and his son, Charles “Carlos” Duncan III, serves on the Houston Methodist Hospital Foundation Board. Additionally, the family established the Charles and Anne Duncan Scholars Program and endowed chairs in nephrology and endocrinology.

Charles Duncan Jr. is also the namesake behind Rice University's Duncan Residential College and was one of the founders of the Greater Houston Partnership. He served as Secretary of Energy during the Carter Administration.

New York Stock Exchange Texas announces location for Dallas headquarters

NYSE Texas

A location has been chosen for The New York Stock Exchange Texas, the new Dallas-based offshoot of the The New York Stock Exchange in New York.

According to a release, the NYSE Texas has leased 28,000 square-feet of space at Old Parkland, the hospital-turned office space at 3819 Maple Ave. in Oak Lawn, where it will operate as a fully electronic equities exchange headquartered in Dallas. The property is owned by Dallas billionaire Harlan Crowe, who acquired it in 2006.

The NYSE is part of the Intercontinental Exchange, Inc., a global provider of technology and data. It was previously the NYSE Chicago, which will close once the bureau in Texas debuts.

They’ve also named a president to the Texas branch: Bryan Daniel, former chairman of the Texas Workforce Commission. In his new role over the NYSE Texas, Daniel will report to President of NYSE Group Lynn Martin.

Relocating from Chicago to Texas was a response to Texas' pro-business profile, Martin says in a statement.

“As the state with the largest number of NYSE listings, representing over $3.7 trillion in market value for our community, Texas is a market leader in fostering a pro-business atmosphere,” Martin says. “We are delighted to expand our presence in the Lone Star State, which plays a key role in driving our U.S. economy forward.”'

The move comes five months after the Texas Stock Exchange — AKA TXSE — announced plans to launch in Dallas and begin trading in 2026, pending approval from the U.S. Securities and Exchange Commission. The Texas Stock Exchange is backed by financial giants such as BlackRock, Citadel Securities, and Charles Schwab.

The NYSE expects the Texas location to open in 2026, where it will operate electronically, with stocks trading across multiple venues regardless of where they are first listed, according to the release.
