Judge Daryl Moore told Kelsi Stayart White that he could stand to work another four months without her while she was on maternity leave, but only if he knew she was coming back. Or else he’d quit.

He was joking, kind of.

Kelsi has become so valuable, Judge Moore said, she is (as another associate described her) like the “plug and play” devices that are intended to work perfectly when first used. “She’s been through trial work, she’s now great at appellate work, she is so versatile she can take on any role,” Judge Moore said. He said she is a rock star lawyer, legally mature beyond her years and despite being in her early 30s, she has an old soul that can read people, read a room and navigate any situation.

Raised in Arlington, Texas, Kelsi developed an insatiable reading habit accompanied by an unquenchable thirst for writing at an early age. She would fill composition books with her own creations, including poems from fourth grade, Star Wars fan fiction from middle school and angst-filled drama from high school. Learning was a treat for her, especially in law school, where she felt she was being educated in the secret code to the world.

An associate at AZA, Kelsi graduated from the University of Texas at Austin with highest honors in English and the University of Texas School of Law with highest honors, serving as an associate editor on the Texas Law Review.

Kelsi met her husband Will through a mutual friend in law school. At first, bizarrely, he thought she might be a dumb blonde who just wanted to socialize and have fun. Kelsi participated in a sports league and mentor program and was quite social in law school. She, in turn, thought he was a weird recluse. Now they have three adorable children, who run them both ragged.

Out of law school, she clerked at the U.S. Court of Appeals for the Fifth Circuit for Judge Leslie Southwick, where she learned a lot about how to map out a strategy for an appeal well before she knew that’s what she wanted to do with her career.

AZA managing partner John Zavitsanos said when Kelsi came to AZA after clerking in Big Law and knowing she wanted something different, her talent was obvious.

“Her judgment approached the tip of Mount Everest from day one,” he said. “She’s arguably the smartest person at the firm, but her intelligence sneaks up on you because there is no arrogance or one-upmanship that comes with it. Instead, she makes people around her feel smarter, in part because she’s a consensus builder. In any dialogue, she challenges an idea without challenging the person.”

Examples of her legal prowess came quickly. She began with trial work. Two years out of law school, she and another AZA associate won a federal jury trial for two insurance clients.  Four years later, she’d made the switch to appellate work and made new law by winning a Fifth Circuit decision in Melinda Abbt v. City of Houston. The court reversed a hostile work environment summary judgment order in a Houston firefighter’s case, setting two new precedents in hostile work environment cases.

She once thought appellate work was for nerds. But she learned she is a bit of a nerd herself and adores finding the unexpected morsel of law that can turn a case. And she learned she was even more at home with the back and forth of an oral argument with appellate judges than making a speech to a jury.

When Texas Lawbook featured a story about Kelsi headlined, “AZA Associate Sets Precedent in Fifth Circuit for Sexual Harassment Victims,” she told them her appellate clerkship taught her “how to look fairly at two sides of the issue and not get caught up in your own argument.”

“You start your legal career just listening to both sides of an argument … instead of starting out your career making an argument,” Kelsi told the legal paper. “I always think about, ‘What should the rule be?’ I wanted my client to win, but I made sure that we were articulating a test and a rule that made sense and had boundaries that made sense, and I think that really helped.”

She’s on the AZA appellate team but still goes to trial, handling the jury charge and appellate issues at trial. That has included working on AZA’s $22 million federal jury win on behalf of the Port of Houston Authority in 2022 and its $32.5 million jury verdict in a complex, multi-party construction dispute a year later.

Other noteworthy appellate wins include defending the denial of an anti-SLAPP motion and frivolousness finding all the way to the Texas Supreme Court, resulting in a six-figure fee award on remand, and securing reversal of a federal agency’s FOIA decision concerning a client’s confidential information.

AZA senior paralegal Lynette Peter said she worked with Kelsi on her first trial and was stunned by her outstanding memory and organizational skills. “She was like my guardian angel. When John Zavitsanos was questioning a witness and made a vague reference to an exhibit he wanted, Kelsi’s photographic memory and an amazing list she’d made of exhibits by topic allowed her to say casually and quickly, ‘Oh, that’s exhibit 43.’ I was amazed.”

AZA partner Shahmeer Halepota said, aside from being universally loved at the firm, intelligent, kind, and empathetic, she is a kind of easy-going bulldog.

“She’s eight months pregnant and led a 12-hour jury charge discussion in a case for a big construction client with eight attorneys on the other side. And she swept the floor with them.” Mr. Halepota said. “One of the senior lawyers on the other side claimed a case she cited was outdated. Kelsi knew the law so well she was able to immediately come back with the full legislative and judicial history to show why he was wrong.”

Despite now having three kids at home, she is still the one he and many colleagues call even on a Sunday when they need a quality analysis of where a case might go. He said she was indispensable when he had weekend questions about a case for Ben & Jerry’s over the unusual agreement the ice cream makers had with Unilever.

AZA partner Kevin Leyendecker worked with Kelsi and remembers being flabbergasted when they were reading a deposition together and Kelsi was at least three pages ahead of him. “She said it is because she loves reading. As a kid she would sneak under the covers and read voraciously. She has this unassuming brilliance.”

Mr. Leyendecker said that when the trial team gets all boys locker-room and rude revving up for trial, she can step in. He said she can, without offense, explain how that might not help them when there are women on the team. “I’m a 55-year-old recovering misogynist whose eyes she helped open,” he said.

Mr. Zavitsanos, a trial lawyer in temperament, heart and mind, said he was thrilled when Kelsi was so immediately terrific in trial and heartbroken when she decided appellate work was for her instead. But she is so good at it, he has made peace with her decision.

“What is the best use of Kelsi White’s talents? Whatever she wants to do,” Mr. Leyendecker, another trial lawyer at heart, said.

In January Kelsi will officially become a partner at AZA.
