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.

Leading Houston healthcare executive named one of America's top CEOs

Best boss

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.

Where founders go to grow: the rise of peer-driven scale support

Inside EO

Entrepreneurship can be exhilarating — but it can also be isolating. Founders often carry the weight of leadership, strategy, hiring decisions, and financial risk without many people who truly understand the pressure. Increasingly, business owners are turning to peer-driven communities for support, insight, and accountability.

One of the most prominent of these communities is the Entrepreneurs’ Organization (EO), a global network of more than 19,000 influential business owners across 86 countries. Built on the belief that entrepreneurs grow best when they learn from one another, EO creates a space where founders can openly share challenges, test ideas, and gain perspective from peers who have faced similar decisions.

A 360-Degree Approach to Growth
Unlike traditional business groups that focus solely on revenue and scale, EO emphasizes holistic development. The organization encourages members to pursue what it calls “360-degree growth” — improving not only their businesses but also their personal lives, leadership skills, and overall well-being.

Through mentorship, peer forums, and curated learning experiences, members gain tools to better balance the demands of entrepreneurship with life outside the office. The goal is not just stronger companies, but stronger leaders.

A Global Network of Entrepreneurs
Connection sits at the center of the EO experience. Members become part of a trusted community of entrepreneurs who exchange ideas, challenge assumptions, and celebrate wins together. These peer relationships often provide clarity that founders can’t easily find inside their own organizations.

EO also opens doors to world-class education opportunities. Members can access proprietary programs and leadership experiences developed in collaboration with leading institutions such as London Business School, Harvard Business School, and The Wharton School. These programs combine academic insight with practical founder experience.

But for many entrepreneurs, the most valuable lessons come directly from fellow members. See how founders feel about the forum experience and the insights they've gained from other participants:

Q: What’s the biggest business change you made because of EO peer advice, and what single metric moved?

A: “My EO Forum encouraged me to slow down long enough to see my blind spots. I stopped running the company purely on instinct and intensity, and I started building real structure, accountability, and leadership around me.” -Jeremy Jenson, Encore Search Partners

A: “Joined and utilized EOS and have quadrupled our business.” —Mark Thiessen, Thiessen Law Firm

Q: What tough moment did EO help you navigate, and what was the outcome?

A: “Changing my business model to focus on one service and one service only — lawn sprinkler system repairs. We have seen greatly improved labor efficiency rates and profit margins.” —Jason Troth, Sprinkler Repair Professionals

A: “My forum helped me navigate and get past a health issue that had derived into a depression.” —Alejandro Cortez, SAI Environmental Services

Q: What’s the best “playbook” you borrowed from another member?

A: “Show up on time. Do what you say. Finish what you start. Say please and thank you.” —Robert Wagnon, W5Ranches

A: “You have to confidently ask for the business. Don’t chase clients at pricing that does not work.” —Pete Patterson, Patterson PC

The Power of Peer Insight
For many founders, the biggest breakthroughs don’t come from books or consultants—they come from conversations with other entrepreneurs who have walked the same path.

Peer-driven organizations like EO are redefining how leaders grow. By combining trusted relationships, shared experience, and access to world-class education, they create an environment where founders can think bigger, lead better, and build businesses that last.

And perhaps most importantly, they remind entrepreneurs that while building a company can feel lonely, they don’t have to do it alone.

Austin company to bring AI-powered school to The Woodlands

AI education

Austin-based Alpha School, which operates AI-powered private schools, is opening its first Houston-area location in The Woodlands.

The 8,000-square-foot school, scheduled to be ready for the 2026-27 academic year, initially will serve students in kindergarten through eighth grade. Alpha says the school will offer “open workshop spaces and innovative classrooms that support personalized instruction, core academics, leadership development, and real-world life skills.”

Alpha sets aside two hours each school day for the AI-driven, self-paced study of core subjects like math, reading and science. The rest of each school day consists of life-skills workshops focusing on topics such as leadership and financial literacy.

Alpha’s school in The Woodlands has begun accepting applications for the 2026-27 school year. Annual tuition costs $40,000.

“The Woodlands is one of the most dynamic, forward-thinking communities in Texas, and Alpha is proud to bring

an innovative educational model that complements its strong academic foundation,” says Rachel Goodlad, head

of expansion for Alpha.

Founded in 2014, Alpha School combines adaptive technology-driven instruction with immersive life-skills workshops. Its model emphasizes mastery-based learning in core subjects alongside development of communication, critical thinking, financial literacy and leadership skills. It operates more than 15 schools across the country.

Elsewhere in Texas, Alpha operates schools in Austin, Brownsville, Fort Worth and Plano. Alpha also operates 12 Texas Sports Academy campuses in Texas, including locations in Houston, Pearland and Richmond, along with a NextGen Academy esports school in Austin, a school for gifted students in Georgetown, and lower-cost Nova Academy campuses in Austin and Bastrop.

Alpha has fans and critics. While supporters tout students’ high achievement rates, detractors complain about the high tuition and the AI-influenced depersonalization of education.

“Students and our country need to be in relationship with other human beings,” Randi Weingarten, president of the American Federation of Teachers, a teachers union, tells The New York Times. “When you have a school that is strictly AI, it is violating that core precept of the human endeavor and of education.”

Alpha co-founder MacKenzie Price, a podcaster and social media influencer, doesn’t share Weingarten’s views.

“Parents and teachers: We need to embrace this change,” Price wrote after President Trump signed an executive order promoting AI in schools.

The Times notes that Alpha doesn’t employ AI as a tutor or a supplement. Rather, the newspaper says, AI is “the school’s primary educational driver to move students through academic content.”
