Dr. Kenneth Liao is the only cardiatric surgeon in Houston — and one of only around 50 in the world — who uses a specific robot to conduct heart surgeries. The robot, known as the da Vinci, was first designed to assist in battlefield procedures.

Now on its fourth generation, the robot allows surgeons like Liao to treat heart diseases and conditions that typically would require open heart surgery through a one-to-two inch incision near the ribs. In many surgeries, it also allows surgeons to keep a patient's heart beating, lowering the risk of stroke.

"It's a totally game changing component to conventional surgery," Liao says. Read more.

matters of the heart

Dr. Kenneth Liao is pioneering a less invasive form of heart surgery at a time when distanced medicine has become more important than ever with the help of six team members and one robot.

As the chief of cardiothoracic transplantation and mechanical circulatory support at Baylor St. Luke's Medical Center, Liao has performed 116 robotic cardiac surgeries since coming on board in 2019 (as of press time). With Liao at the helm, Baylor St. Luke's has become a top cardiac robotics program in the country and is the only hospital in Houston to practice this highly-specialized form of surgery.

Liao's four-armed robot friend is known as the da Vinci robotic system and was first designed to assist in battlefield procedures. Now on its fourth generation, the robot allows surgeons like Liao to treat heart diseases and conditions that typically would require open heart surgery through a one-to-two inch incision near the ribs. In many surgeries, it also allows surgeons to keep a patient's heart beating, lowering the risk of stroke.

"It's a totally game changing component to conventional surgery," Liao says, who's one of about 50 surgeons in the country with his level of command over the tool.

Once inside, the da Vinci robot uses tiny instruments to perform surgical practices from suturing to cutting to tying a knot all within the rigid chest cage, which in a typical open heart surgery would have to be broken to perform such tasks.

The surgeon, who's seated about 10 feet away from the patient, controls the tools through a joystick connected to a computer console that shows an enhanced 3D view of the patient's chest. Liao says the screen provides a better visual of the heart than if he was seeing it with his own eyes, as it magnifies the field of surgery tenfold. This method also gives surgeons a better view of areas of the heart that they cannot easily see from above during traditional procedures.

The da Vinci can be used for bypass, grafting, pacemaker, and valve repair surgeries, and it has been proven to result in less blood loss and a faster, less painful recovery. Similar technology has also been adopted for prostate and gynecological surgeries. "It gives you the advantage of minimizing the trauma," Liao says.

And though the da Vinci was developed years before the pandemic, it puts patients at a lower risk of exposure to any outside contaminants, Liao adds, as the robot alone is interfacing with the patient through a small port, compared to doctors, nurses, and assistants hovering over an open chest cavity.

"Technology will theoretically reduce a patient's exposure to COVID in the operation room," he says. "I think that's common sense."

Liao was an early adopter of robotics, when the technology was much less user friendly. He performed the first robotic heart surgery in the state of Minnesota in 2003 and has worked with the developers of the da Vinci ever since to help improve the product after many other surgeons dismissed it.

He says today there is a renewed interest in the highly technical process and he believes it will become an emphasis for younger surgeons.

"This generation of surgeons are young and they are very indebted to computer technology and games. For them looking at screens and controlling the hand joystick control is much more familiar than for the older generation that was trained 20 years ago." he says.

The incredible technology helps, too. "A lot of times, as surgeons, we train in the old way. It's very difficult to change the systems," he says. "You need a major technology revolution to change the teaching and training."

Houston leads U.S. with the biggest surge in millionaire renters

Rent Report

The number of millionaire renters and homeowners in the U.S. has surged over the last five years, and Houston has soared ahead of the rest with the largest growth rate among these affluent renter households.

Houston leads the nation with the No. 1 increase in millionaire renters from 2020 to 2024, a new RentCafe study found. The number of these wealthy households increased from 18 to 232 over the last five years, representing a 1,189 percent growth rate.

"The pandemic accelerated the shift as remote work pushed the wealthy to relocate to lower-tax metros like Houston, where millionaire renters grew 13-fold, versus 3.9-fold for owners," the report said. "Granted, 232 households is still a tiny fraction of the Houston metro’s roughly 2.7 million households, but the growth rate far outpaces any other major metro."

Nationwide, the number of millionaire renter households grew 229 percent from 2020 to 2024, outpacing the 193 percent growth rate among millionaire homeowners.

Dallas was the only other Texas metro to crack the top 10. The number of millionaire renter households in North Texas has more than quintupled, from just 30 in 2020 to 165 in 2024. That represents a growth rate of 450 percent, which — surprisingly — is only the eighth highest nationwide.

But when it comes to the largest populations of millionaire renters, New York City and San Francisco still lead the way. New York claimed the No. 1 spot with nearly 7,300 millionaire renters living in the city in 2024. Houston ranked 12th on that list.

Elsewhere in Texas, Austin and Dallas ranked as the 16th and 17th, respectively, for the largest population of millionaire renters. There were 206 millionaire renters living in Austin in 2024, and 165 in Dallas.

This is who the typical millionaire renter is
The report also revealed a surprising statistic about the typical millionaire renter in the U.S. — a lot of them are millennials working in "white-collar, high-earning fields."

"Nearly half (49 percent) of millionaire renters are Millennials, and the number of affluent Millennial renter households surged 392 percent during the five-year period," the report said. "Gen X follows with 33 percent of millionaire Gen X households renting after increasing by 147 percent."

The report continued, "Although Gen Z still represents a small share of millionaire renters (just 2 percent of the total), no generation has expanded faster: Gen Z millionaire renter households leaped from fewer than a dozen to more than 400 — a tiny cohort today, but one that was virtually nonexistent five years ago."

The top three most common professions for millionaire renters are chief executives, software developers, and managers, the report additionally found. In Houston, the surge of wealthy newcomers are mostly executives, professional athletes, and entertainers.

"These roles tend to generate steady, substantial income without necessarily tying workers to one location, making renting a practical fit, rather than a financial necessity," the report said.

Hotspots for millionaire homeowners
In RentCafe's separate list comparing the top 10 most popular U.S. metros for millionaire homeowners, Houston ranked 12th nationally with 4,374 millioniare homeowners living in the metro as of 2024. These wealthy Houstonians are most likely working as chief executives, physicians, managers, and lawyers and judges.

Houston has already proven to be a hotspot for millennial homebuyers, and the latest RentCafe data says millennials make up 19 percent of all millionaire homeowners in the U.S. Gen Xers and Baby Boomers still maintain the largest shares of millionaire homeowners nationwide, at 45 and 33 percent, respectively.

Dallas (No. 10) and Austin (No. 20) also appeared among the hottest metros for millionaire homeowners.

Only one Texas city appeared among RentCafe's list of the 20 fastest-growing metros for millionaire homeowners: College Station ranked 13th nationwide with a growth rate of 1,329 percent. From 2020-2024, the number of millionaire homeowners residing in College Station grew from 14 to 200.

Houston ranks high on best cities for small-business expansion report

business growth

For small businesses looking to expand, Houston might be the right place.

Among 56 major U.S. metros, Houston grabbed the No. 6 spot on a new list of the metros boasting the strongest environments for small-business expansion.

A 2025 report from the state comptroller’s office showed roughly 970,000 small businesses operate in the 13-county Gulf Coast region. The region includes the majority of the Houston metro area.

“Whether it’s a family-owned shop on Main Street or a fast-growing startup, small businesses power our state’s economic engine, create opportunity, and strengthen the character of every Texas community,” Kelly Hancock, who was interim state comptroller when the report was released, said in a press release.

Business lending platform Clarify Capital analyzed five factors to develop the list: job growth, business entry and exit, net job creation, and unemployment.

Overall, the Nashville area claimed the No. 1 spot on the list. Other major Texas metros also cracked the top 10, including Austin at No. 3 and Dallas-Fort Worth at No. 7.

“The highest-ranking metros combine labor-market momentum with steady business formation and relatively favorable local employment conditions,” Clarity Capital says.

The Houston metro ranked sixth for job growth, 11th for business entry rate, 38th for business exit rate, second for net job creation rate, and 50th for unemployment rate.

“For business owners, the ranking is a starting point rather than a guarantee,” Clarify Capital says. “Local demand, competition, operating costs, and access to capital still shape whether an expansion works.”

“Building enough cash-flow room for hiring, equipment, and unexpected expenses can help small and midsize business owners take advantage of a strong market without stretching the business too thin,” the company adds.

Of course, money fuels small-business expansion in the Houston area or anywhere else.

According to an analysis of SBA loan data by feasibility consulting firm MMCG, the Houston metro area saw 1,685 approvals for 7(a) loans and 101 approvals of 504 loans in the federal government’s 2025 budget year. The approval numbers for both loan categories increased from the previous year.

Altogether, the 7(a) and 505 loans exceeded $1 billion.

The data from the U.S. Small Business Administration suggests small-business expansion may be on the rise in the Houston area.

Further potential evidence of small-business expansion in the Houston area: The region experienced a 92 percent rise in account applications from 2024 to 2025 submitted to Bluevine, a small-business banking platform. The Houston metro ranked fifth for the number of Bluevine small-business applications in 2025.
