Wirth Law Office Among Top Rising US Firms in 2026
No. 2628
A sustained commitment to growth that has built greater capacity, broader reach and stronger systems for serving clients has also earned Wirth Law Office a place on the 2026 Inc. 5000 listing. The preeminent entrepreneurial publication listed Wirth Law Office as No. 2628 among America’s fastest-growing private companies.
The recognition reflects growth from 2022 through 2025. More importantly for the people who come to us for help, that growth has allowed Wirth Law Office to keep investing in the attorneys, staff, technology and operating systems behind every client relationship.
“Growth is meaningful because it gives us more ways to help people facing consequential problems,” said founder James M. Wirth. “The recognition is gratifying, but our focus is the same as it was when we opened our doors: build a stronger firm, serve more Oklahomans and ‘Make Law Easy.’”
Growth With a Purpose
Wirth Law Office began in Tulsa in 2010 and now serves clients through most of the state from offices in Tulsa, Oklahoma City, Okmulgee, Muskogee, Wagoner, Tahlequah and Bartlesville.
Our attorneys represent people in municipal, district, tribal and federal courts, with much of the firm’s work involving family law, criminal defense and probate.
Those matters are often deeply personal. A divorce, custody dispute, criminal charge, probate matter or other legal crisis can arrive at a moment when someone already has more than enough to think about. Our goal is to make the legal process simple so clients can focus on navigating consequential personal matters.
Growth gives us more resources to bring to those moments.
As Wirth Law Office has expanded, the firm has developed centralized operations, technology and client-service systems that allow local attorneys to draw on a larger organization while continuing to provide individualized representation.
That can mean better access to information, more consistent communication, stronger administrative support and more of the firm’s resources working behind the attorney handling a client’s case.
The aim is not simply to become larger. It is to become more capable.
Personalized Service, Powerhouse Backing
Legal problems do not arrive as abstract units on a production line. They arrive in individual lives, with individual facts, families, histories and consequences.
For that reason, Wirth Law Office has worked to pair the efficiencies of a larger professional-services organization with the personal representation people expect from their lawyer.
A client should not have to understand the machinery behind a law firm to benefit from it. Better systems should make communication easier. Better technology should make information more accessible. Stronger operations should give attorneys more support. A broader organization should give clients more resources without making their experience feel less personal.
That is the idea behind the firm’s longstanding promise: “Make law easy!”™
The law itself is not always simple, and the circumstances that bring people to a lawyer rarely are. But the process of getting answers, understanding options and knowing what happens next can be made clearer.
A Year of Growth and Recognition
The Inc. 5000 ranking comes during a broader period of recognition for Wirth Law Office and James Wirth.
Wirth was selected for inclusion in Super Lawyers in both 2025 and 2026, and Oklahoma Magazine named him among its 2026 Best of the Best attorneys.
Wirth Law Office and James Wirth have also been named 2026 Tulsa World Best in the World finalists for Best Law Firm and Best Attorney, with winners to be announced Sept. 17.
Those honors measure different things and come from different organizations. Together, however, they mark a period in which the firm has continued to grow while earning broader recognition from the legal profession, the business community and the communities Wirth Law Office serves.
What the Inc. 5000 Measures
The Inc. 5000 ranks privately held U.S. companies according to percentage revenue growth over a three-year period. For the 2026 list, Inc. measured growth from 2022 through 2025.
To qualify, companies must meet Inc.’s revenue requirements and be U.S.-based, privately held, for-profit and independent.
The 2026 honorees span industries ranging from technology and advanced manufacturing to healthcare, consumer products and professional services. According to Inc., companies on this year’s list achieved median three-year growth of **130 percent** and collectively added more than **627,000 jobs** during that period.
Inc. editor-in-chief Mike Hofman said the companies on the list reflect perseverance, creativity, resilience and the customer focus required to build organizations with lasting impact.

Building What Comes Next
For Wirth Law Office, the Inc. 5000 ranking is not an endpoint. It is evidence that the firm has been able to keep building. That work continues.
The firm will continue investing in people, technology, systems and local offices that help attorneys serve clients effectively while keeping the focus where it belongs: on the person who came through the door with a problem that matters to them.
Growth is useful when it creates more capacity to listen, more resources to act and a stronger organization behind the individual attorney-client relationship.
That is what Wirth Law Office intends to keep building. And that remains the purpose behind our promise to “Make law easy!”™
