The Oldest Continuously Operating Law Firm in Texas

Galveston in the mid-1840s was Texas's gateway to the world — its largest city, a bustling port fueled by cotton trade, immigration, and the optimism of a young republic-turned-state. Into this dynamic environment arrived William Pitt Ballinger (1825–1888), a Kentucky-born veteran of the Mexican War who moved to Galveston around 1843–1845 to study law under his uncle, James Love.

On November 13, 1846, Ballinger received the very first law license issued by the State of Texas through the First Judicial District Court — a foundational moment that marked the formal beginning of organized legal practice in the state. That same day is recognized as the firm's founding date.

Ballinger's initial partners were John M. Jones and Jonas Butler, forming the firm Jones, Butler & Ballinger. Early partnerships reflected the era's fluid professional networks: by 1854, Ballinger had partnered with Thomas McKinney Jack (his brother-in-law) and M. L. Mott. He also served as United States District Attorney for Texas (1850–1854).

Ballinger quickly established the firm's reputation for precedent-setting work, notably representing Galveston wharf owners in a landmark dispute against the City of Galveston that reached the Texas Supreme Court in 1859. His civic and political involvement — including service as a Confederate receiver during the Civil War, declining appointments to the Texas Supreme Court in 1871 and 1874, and participation in the 1875 Constitutional Convention on the Judicial Committee — underscored the firm's role not just as advocates but as shapers of Texas law and governance.

These early decades highlight a key nuance of the firm's history: law practice in antebellum and Reconstruction Texas was intensely personal and community-oriented. Partnerships formed and reformed amid economic volatility, yellow fever epidemics, and political upheaval. Yet the practice remained anchored in Galveston, serving merchants, shipowners, and the growing port economy.

The Great Storm of 1900 — the deadliest natural disaster in U.S. history, which killed thousands and nearly erased the city — tested the firm's resilience. The firm not only survived but contributed to rebuilding efforts, much as it would later aid recovery from the 1947 Texas City disaster (a massive chemical explosion that devastated the nearby mainland) and Hurricane Ike in 2008.

These events underscore a recurring theme: the firm's deep integration into Galveston's fabric. Its attorneys advocated for infrastructure, commerce, and municipal growth, helping the island recover economically and legally amid shifting trade patterns, the rise of Houston as a rival port, and industrial expansion along the Gulf Coast.

As Galveston evolved from a cotton port to a diversified economy involving shipping, tourism, insurance, and public entities, the firm expanded its expertise accordingly. Maritime and admiralty law, insurance defense, construction disputes, and real estate matters became cornerstones — practice areas perfectly suited to a barrier-island community vulnerable to hurricanes yet vital to Gulf commerce.

Today, Mills Shirley LLP operates with a modern edge while honoring its heritage. With a team of experienced, board-certified attorneys led by Managing Partner Robert E. Booth, the firm handles complex commercial litigation, business transactions, employment and labor defense, probate and estate planning, municipal law, appellate practice, and coastal and industrial disputes.

It represents businesses, governmental entities, insurers, and individuals across Galveston County and beyond, with offices strategically located in Galveston's historic district. Specialties now explicitly include fiduciary litigation, personal injury defense, and public entity representation — evolutions driven by 21st-century demands such as regulatory compliance, disaster recovery claims, and economic redevelopment.

Unlike many historic firms that dissolved or relocated, Mills Shirley remained physically and philosophically rooted in Galveston. Family involvement gave way to merit-based partnerships that preserved institutional knowledge. Community leadership — from setting early legal precedents to advocating for growth — has been a constant thread, distinguishing it from purely transactional practices.
