Biography
Nathan Campbell is a trial lawyer handling a variety of business litigation ranging from patent disputes to employment and real estate matters. In his first two years of practice, he played a significant role in two trials that led to impressive jury verdict wins for his clients.
In a case involving business disparagement that made national news, Mr. Campbell examined witnesses, argued motions, and drafted briefs. His client prevailed with a verdict that totaled $7.8 million, including interest. In the second trial, which involved a $120 million claim against the firm's client for harassment and discrimination, he argued the charge conference, drafted motions, and assisted with witness preparation. A federal jury unanimously held the client not liable.
Since then, Mr. Campbell has served as lead counsel on an attorneys’ fees bench trial and has delivered opening statements and examined witnesses in arbitration. Outside of trial, Mr. Campbell’s practice has encompassed a variety of civil litigation.
Representative examples of his experience include drafting briefs and motions in commercial litigation, deposing witnesses in patent and construction disputes, and successfully handling employment and real estate matters. In 2017, he successfully excluded an opposing party’s expert after deposing the expert, drafting the motion to exclude, and arguing the motion in court. In 2018, Mr. Campbell successfully defended a motion for summary judgment on an eight-figure claim, in which he primarily drafted the briefing and argued the defense at the summary judgment hearing.
A Harvard Law grad, Mr. Campbell was an article editor of the Harvard Journal of Law & Technology and volunteered as a student attorney at the Harvard Prison Legal Assistance Project. Before law school, he was a paralegal in the Boston office of the U.S. Attorney’s Office for the District of Massachusetts, where he assisted in False Claims Act investigations and litigation.
Mr. Campbell is also a graduate of the College of Holy Cross and completed intensive post-graduate Mandarin language training at National Taiwan University in Taipei, Taiwan.

Additional Information
- Representative Cases
- In 2024, Mr. Campbell worked in concert with the federal government to help secure the largest settlement ever for Medicare fraud over concurrent surgery claims. AZA saw their whistleblower client receive $3 million of the recovery.
- In a 2024 business divorce trial where the plaintiff presented damages of up to $82 million, a Harris County jury unanimously found he should take nothing and returned a verdict in favor of AZA’s clients. Mr. Campbell delivered the opening statement for his clients and examined multiple witnesses, including a damages expert.
- In 2023, a Harris County jury awarded AZA’s energy client $2.4 million in attorney’s fees in a breach of contract case arising from a $90 million asset purchase. The seller sought approximately $30 million from Mr. Campbell’s client but took nothing. Mr. Campbell presented at opening, and took such key witnesses as the client’s Chief Financial Officer, and the opposing party’s damages expert.
- In 2023, after a complex six-week case involving the construction of Houston Midtown apartments, a Harris County jury awarded Mr. Campbell’s clients $32.5 million. Mr. Campbell presented at opening, argued during closing, and presented or cross-examined five witnesses.
- In 2022, Mr. Campbell helped try and win a multimillion dollar three-week jury trial involving breach of contract and breach of fiduciary duty on behalf of a national energy company.
- In 2021, the Supreme Court of Texas affirmed the Second Court of Appeals’ judgment enforcing an arbitration provision, which paved the way for the firm’s client to proceed against its counterparty to recover in excess of $15 million under an indemnity provision. Mr. Campbell helped draft the appellate briefing.
- In 2021, Mr. Campbell successfully settled a case for a commercial property owner and management company on a seven-figure premises liability lawsuit.
- In 2020 and 2018, Mr. Campbell successfully defended motions for summary judgment on two separate eight-figure claims, in which he primarily drafted the briefing and argued the defense at the summary judgment hearings. One case involved executives seeking compensation and benefits from their current employer. The second involved a mixed-use property developer seeking damages against a contractor and a surety on an over $60 million project.
- In 2020, Mr. Campbell cross-examined two key witnesses, directly examined a third, and delivered closing arguments in an international commercial arbitration over a commodity trading dispute. In addition to awarding his client damages, the arbitration award quoted Mr. Campbell’s cross-examination of the opposing party’s principal when disposing of an entire counterclaim in favor of Mr. Campbell’s client.
- In 2019, Mr. Campbell was lead counsel in a successful bench trial on attorney’s fees and declaratory judgment in a tech start-up investor dispute. The Court found that the firm’s client was entitled to preferred stock rather than common stock, as the defendant was arguing.
- In 2019, he successfully argued and defended summary judgment for briefing on land-use restrictions where he was the primary author. Following the summary judgment hearing, the judge unexpectedly indicated that he wanted to conduct a bench trial on the case in five days. Mr. Campbell led the trial preparation efforts and showed up ready to try the case on the fifth day. The opposing party caved in a settlement favorable to Mr. Campbell’s client before opening statements. The result was the preservation of a century-old deed restriction that has helped maintain the aesthetic and charm of a Montrose neighborhood from a developer threatening to sue neighbors and the civic association who were attempting to enforce the restrictions. This matter was handled on a pro bono basis.
- In 2018, the firm’s client was awarded damages in an arbitration after the respondent ordered specialty-manufactured goods used in oil field services and did not pay for them.
- In 2017, Mr. Campbell successfully excluded an opposing party’s expert after deposing the expert, drafting the motion to exclude, and arguing the motion in court. The case was a construction dispute between a property owner whose building flooded following rain and the engineer who designed the building.
- In 2016, Mr. Campbell was on the trial team for a janitorial contractor who hired AZA to end a nearly 10-year-old case against a union that lied about the cleaning company and caused the company to lose business. AZA stopped the stalling, got the case to trial, and obtained a jury verdict that, with interest added, totaled $7.8 million for the firm’s client. The case made national news.
- In 2015, National Oilwell Varco was sued for $120 million by eight former employees claiming they were treated differently because of their race. Mr. Campbell joined the trial team after the client offered a substantial settlement that was refused. The client won a take-nothing verdict in a hard-fought case where plaintiffs were represented by a high-profile civil rights lawyer.
