The Jimmerson Law Firm has deep roots in Las Vegas that date back to 1976 when Jim Jimmerson was admitted to the Nevada State Bar.

‍

As the nation's 250th birthday approaches, Jimmerson is celebrating his 50th anniversary practicing law.

‍

Founded by Jim Jimmerson in 1983, his firm specializes in high-stakes civil litigation, complex commercial and business disputes, high net-worth divorces and hotly contested child custody disputes. His oldest son, James, is a partner in the firm and is an accomplished AV-rated attorney in his own right.

‍

A Las Vegas native, Jimmerson's parents were wheat farmers in Southern Kansas, who relocated to Nevada in the mid-1940s. His mom, Lorene Mae Jimmerson, was a cocktail waitress at the Flamingo, which was operated by mobster Ben "Bugsy" Siegel, and his dad, J. L. Jimmerson, was a shill in the gaming industry where he would "warm up" the tables for gaming customers. His dad later became a dealer, floorman and shift boss in the industry. Both eventually became real estate brokers, owning their own business Sunrise Realty, until they retired.

‍

"I was very proud of my parents (who were civil rights advocates)," Jimmerson said. "My father helped start the Evening Optimist Men's Club, which then, in turn, formed and sponsored a racially diverse, all-boys choir. In 1959, the choir, including Jimmerson, as an 8-year-old, performed on the Ed Sullivan Show, nationally televised from the Desert Inn Hotel pool.

‍

Jimmerson said he was imbued with a sense of justice growing up in the 1950s and 1960s in Las Vegas. He attended George Washington University for his first, third and fourth years and spent his sophomore year studying abroad in Paris at the College Américain du Paris. He then completed his formal education by attending Columbia Law School in New York City.

‍

"I always wanted to be a lawyer since my junior year at the original Las Vegas High School", Jimmerson said, "I made that decision when I realized that I couldn't be James Bond or be a spy with the CIA."

‍

Following law school, Jimmerson said he had to choose between criminal and civil law. In 1976, he interviewed with criminal attorney (and later Las Vegas mayor) Oscar Goodman, but he ended up choosing civil law working with Morton Galane, a civil law trial lawyer.

‍

Jimmerson started his own firm in 1983. He said he is probably best known, today, for his trial skills, both jury and non-jury, and his emphasis on both family and business law, which makes up about 75 percent of his business, while the remaining 25 percent is composed of civil practice in several areas including probate litigation, corporate transactions and litigation, real estate, professional liability and personal injury. He has a wide practice that handles other matters, as well.

‍

As the years passed, Jimmerson became a "lawyer for the stars." While he declines to identify or confirm his vast business and individual client base, public records reveal his representation of Steve Wynn, Fred Glusman, Fletcher Jones II, Terry Fator, Mike Tyson, Floyd Mayweather, Wayne Newton, Sheldon Adelson, Carmen Electra and Pamela Anderson, to name just a few.

‍

Jimmerson said the firm, at its largest, had five partners in the 1980s and 1990s and was based in downtown Las Vegas before relocating to Summerlin in 2025. Jimmerson adds: "I am blessed that some of Nevada's greatest lawyers and judges worked with me over the years, too many to name here. Our firm's alumni, and our current legal team, were, and are, exceptional, skillful, ethical and hard-working. They were/are absolutely lethal."

‍

Jimmerson said he first gained notoriety handling a divorce case in California involving car dealer Fletcher Jones Sr. Jimmerson was successful in negotiating setting aside a pre-martial agreement that Jones' wife, Beverly, had signed, which resulted in her receiving a huge settlement.

‍

"She became the toast of the town, and lucky for me, she liked to talk, and that was a major turn of events" (getting me recognized and building my reputation at an early point in my career)," Jimmerson said. "Ms. Jones was a wonderful person. To this day I have been privileged to represent good people, salt of the earth, people who helped build Southern Nevada and who had the vision to see its potential," Jimmerson said.

‍

Jimmerson also represented boxer Mike Tyson in getting his license back after he was stripped of it after biting off the ear of Evander Holyfield in 1997. The Nevada Athletic Commission initially denied Tyson's application for reinstatement until he hired Jimmerson in 1998.

‍

"That went viral at a time when "viral" wasn't even a word used to describe world-wide media coverage," Jimmerson said. "I was giving remarks to ESPN, The New York Times, Sports Illustrated and many other news outlets. I was everywhere." Mike Tyson had been on the sidelines for a year, and his application for reinstatement had initially been handled by a law firm from Southern California. The application was rejected by the NAC.

‍

"It was a disaster," Jimmerson observed. "That led to the termination of the California law firm, and the hiring of our law firm."

‍

MGM and Showtime were urged to hire Jimmerson to represent Tyson. They did so. Jimmerson's strategy was to humanize his client, to show Mike Tyson was a good and decent man. With MGM's, Showtime's and HBO's help, Jimmerson formed a juggernaut.

‍

"I asked to bring to the administrative hearing Evander (Holyfield), Earvin, (former NBA superstar Earvin "Magic" Johnson) and the single biggest name in professional boxing, Muhammad Ali, to testify on Tyson's behalf," Jimmerson said. The Commission voted 4-1 to reinstate Tyson's license.

‍

Jimmerson said he's proud of the 50-year longevity of his law firm when others have come and gone over the years. "Before I graduated law school, I began my legal work as a law clerk for Lionel, Sawyer and Collins, the state's largest law firm at the time," Jimmerson said. "Today they are dust."

‍

Jimmerson is married to his wife, Carol, for 34 years, and they have four children: James, Chad, Jacob (deceased) and daughter, Bentley. His son, James, has been practicing law for 15 years, and is a partner with The Jimmerson Law Firm. Bentley, a graduate of Trinity College, Ireland's most prestigious university, is completing her law exams in Dublin, Ireland and will be practicing law there at the Clark Hill law firm. Chad is an HVAC technician and owns a small biometrics business, Executive Biometrics.

‍

"While I have worked hard all of my life and have devoted my life to the law, I am most proud of my family." "I am married to a beautiful woman, inside and out," Jimmerson said. "Our family is my legacy. Our children and grandchildren bring me such joy. Family is No. 1."
