Three Houston-area CEOs are doing a exemplary job of leading, says a new report.

Dr. Peter Pisters (MD Anderson Cancer Center), Dr. Marc Boom (Houston Methodist), and Worthing Jackman (Waste Connections) appear on Glassdoor's new list of the top 100 CEOs for 2021.

Pisters scored particularly well; he ranked third overall on the prestigious list and earned a 99-percent approval rating from MD Anderson employees who shared anonymous feedback on the Glassdoor platform, which publishes reviews and salary information for employers.

Meanwhile, Boom ranked 60 overall with a 93 percent approval, while Jackman came in at 76 overall with a 92 percent approval.

Other Texas executives appearing on the new Glassdoor list are:

  • Seventh-ranked Charles Butt, CEO of San Antonio-based H-E-B (96 percent).
  • Fourth-ranked Gary Kelly, who just announced he's stepping down as CEO of Dallas-based Southwest Airlines (98 percent approval).
  • 55th-ranked Sean Yalamanchi, chairman and president of Richardson-based Infovision (93 percent approval).

"Over the past year, company leaders around the world faced unprecedented challenges to support employees during the COVID-19 crisis. Now, the employees have spoken and it's clear that these CEOs excelled and found new ways to support their people when the world of work flipped upside down," Christian Sutherland-Wong, Glassdoor's CEO, says in a news release.

Houston-based MD Anderson regularly garners praise for its breakthrough cancer treatments. Now, its leader is garnering attention as one of the country's top CEOs.

Dr. Peter Pisters, who's been president of MD Anderson Cancer Center in Houston since 2017, is among the honorees in Glassdoor's annual Employees' Choice Awards, recognizing the top 100 CEOs of 2019. Pisters ranks 47th on the list, with an impressive 94 percent approval rating from his employees. He appears in the category for large employers.

In a letter sent to faculty and staff after he was named to the position, Pisters wrote that he looked forward to collaborating with his new MD Anderson colleagues on the hospital's "profound purpose" of wiping out cancer.

"My promise to you is we will do so with a strong moral compass and principles of values-based servant leadership," Pisters wrote. "The honor of serving as your president is one that I both respect and am humbled by, and I will spare no effort in working with you to build upon and extend MD Anderson's unparalleled history of success."

Sitting atop the Glassdoor list of CEOs at large employers is Pat Gelsinger, CEO of VMWare. Charles Butt, chairman and CEO of San Antonio-based H-E-B, is in second place, followed by In-N-Out Burger's Lynsi Snyder, T-Mobile's John Legere, and Adobe's Shantanu Narayen.

"Under [Butt's] leadership, the desire to constantly innovate has led to new store concepts, the creation of one of the most successful private label programs in the country, and the commitment to build out state-of-the-art digital products and services to complement H-E-B's world-class stores," the company says in a release about the Glassdoor recognition.

The remaining Texans on the Glassdoor list are all from the Dallas area: Gary Kelly, chairman and CEO of Dallas-based Southwest Airlines; Peter Strebel, president of Dallas-based Omni Hotels & Resorts; and Steve Barick, chief operating officer of Irving-based Highgate Hotels, all in the category for large employers.

Kelly, who has worked at Southwest for more than 30 years, is the highest ranked CEO in Dallas, landing at No. 35 with an approval rating of 95 percent.

At No. 58 is Strebel, who garnered an approval rating of 94 percent. He's a longtime employee of Omni; in 2018, he was promoted to president.

Barick, the longtime chief operating officer of Irving-based Highgate Hotels, claims the 97th spot with an approval rating of 90 percent.

Zach Ellis Jr., founder and general partner of South Loop Ventures, says the firm wants to address the "billion-dollar blind spot" of inequitable distribution of venture capital to underrepresented founders of color. The Houston-based firm recently closed its debut fund for more than $21 million. Learn more.

Ty Audronis and his company, Tempest Droneworx, made a splash at SXSW Interactive 2025, winning the Best Speed Pitch award at the annual festival. The company is known for it flagship product, Harbinger, a software solution that agnostically gathers data at virtually any scale and presents that data in easy-to-understand visualizations using a video game engine. Audronis says his company won based on its merits and the impact it’s making and will make on the world, beginning with agriculture. Learn more.

Houston-based Persona AI and CEO Nicolaus Radford continue to make steps toward deploying a rugged humanoid robot, and with that comes the expansion of its operations at Houston's Ion. Radford and company will establish a state-of-the-art development center in the prominent corner suite on the first floor of the building, with the expansion slated to begin in June. “We chose the Ion because it’s more than just a building — it’s a thriving innovation ecosystem,” Radford says.

Houston university to launch artificial intelligence major, one of first in nation

BS in AI

Rice University announced this month that it plans to introduce a Bachelor of Science in AI in the fall 2025 semester.

The new degree program will be part of the university's department of computer science in the George R. Brown School of Engineering and Computing and is one of only a few like it in the country. It aims to focus on "responsible and interdisciplinary approaches to AI," according to a news release from the university.

“We are in a moment of rapid transformation driven by AI, and Rice is committed to preparing students not just to participate in that future but to shape it responsibly,” Amy Dittmar, the Howard R. Hughes Provost and executive vice president for academic affairs, said in the release. “This new major builds on our strengths in computing and education and is a vital part of our broader vision to lead in ethical AI and deliver real-world solutions across health, sustainability and resilient communities.”

John Greiner, an assistant teaching professor of computer science in Rice's online Master of Computer Science program, will serve as the new program's director. Vicente Ordóñez-Román, an associate professor of computer science, was also instrumental in developing and approving the new major.

Until now, Rice students could study AI through elective courses and an advanced degree. The new bachelor's degree program opens up deeper learning opportunities to undergrads by blending traditional engineering and math requirements with other courses on ethics and philosophy as they relate to AI.

“With the major, we’re really setting out a curriculum that makes sense as a whole,” Greiner said in the release. “We are not simply taking a collection of courses that have been created already and putting a new wrapper around them. We’re actually creating a brand new curriculum. Most of the required courses are brand new courses designed for this major.”

Students in the program will also benefit from resources through Rice’s growing AI ecosystem, like the Ken Kennedy Institute, which focuses on AI solutions and ethical AI. The university also opened its new AI-focused "innovation factory," Rice Nexus, earlier this year.

“We have been building expertise in artificial intelligence,” Ordóñez-Román added in the release. “There are people working here on natural language processing, information retrieval systems for machine learning, more theoretical machine learning, quantum machine learning. We have a lot of expertise in these areas, and I think we’re trying to leverage that strength we’re building.”
