A New Orleans Plaintiff-Side Practice

Cassie Preston Gailmor is a New Orleans trial attorney and the managing partner of Gailmor Law Group, LLC, a plaintiff-side firm focused on personal injury, work-related injuries, premises-liability claims, construction incidents, and serious civil disputes. Her practice sits in the high-pressure space where injured clients, insurers, employers, property owners, and corporate defendants often collide.

Gailmor’s work is built around preparation. Personal injury litigation is rarely won by volume or slogans. It turns on records, timing, preservation of evidence, medical proof, witness development, insurance pressure, and a lawyer’s ability to keep a case from being reduced to a claims file. Gailmor’s practice is shaped around that discipline: building the record early, forcing attention to the facts, and pressing for recovery when a client’s health, income, and future have all been disrupted.

Gailmor founded Gailmor Law Group in 2024 after more than a decade in civil litigation. The firm’s practice reflects the realities of Louisiana injury work: car accidents, job-related injuries, construction matters, slip-and-fall claims, premises-liability disputes, and cases where the legal issues often overlap with insurance, medical causation, and contested responsibility.

Her firm’s model is deliberately personal. Injury clients often arrive at a lawyer’s office at the worst point in their lives, carrying medical bills, missed work, property damage, and the uncertainty of whether anyone with power over the claim will take them seriously. Gailmor’s role is to bring structure to that moment. The work starts with facts and documentation, then moves into strategy: who is responsible, what proof exists, what coverage applies, and how to keep the case moving when delay benefits the other side.

That focus gives her practice a clear lane. Gailmor is not operating as a remote case manager. Her public profile and professional record point to a lawyer working directly in the machinery of plaintiff litigation, where leverage has to be earned through preparation.

Education, Admission, and Professional Formation

Gailmor earned her Bachelor of Science in Political Science from Louisiana State University and her Juris Doctor from Loyola University New Orleans College of Law. She was admitted to practice law in Louisiana in 2010.

That Louisiana foundation shapes the work. Personal injury and premises-liability cases in the state require close attention to fault, notice, causation, damages, insurance conduct, and the local procedures that can determine whether a case gains momentum or stalls. Gailmor’s career has developed inside that environment, in a New Orleans legal community known for demanding civil litigation and active trial-law institutions.

Bar Leadership and Recognition

Gailmor has also built a visible role within Louisiana’s plaintiff and young-lawyer communities. She serves on the Board of Governors for the Louisiana Association for Justice, chairs the New Orleans Bar Association’s Personal Injury Section, and is a barrister in the St. Thomas More American Inn of Court. She previously chaired the New Orleans Bar Association Young Lawyers Section in 2023.

Her recognitions include selection to Louisiana Super Lawyers “Rising Stars” from 2016 through 2025, recognition among Top 40 Under 40 Louisiana Lawyers, and inclusion in Top Lawyers in America “Ones to Watch” in 2020 and 2021. Those honors fit the broader arc of her career: a lawyer who moved from civil-litigation practice into firm ownership, bar leadership, and a focused plaintiff-side platform.

The Litigation Lane

The through-line in Gailmor’s profile is not simply personal injury. It is the practical work of representing people whose claims can be minimized, delayed, or boxed into categories that do not capture the full damage. Car accidents, work injuries, construction incidents, and premises-liability cases all require the same core litigation habits: listen carefully, document aggressively, identify leverage, and prepare as though the case may need to be tried.

For clients, that approach can change the entire posture of a case. A claim that begins as an insurer’s file becomes a factual record. A disputed injury becomes medical proof. A vague denial becomes a set of positions that can be challenged. Gailmor’s practice is built for that transformation.
