His years at Swanson, McNamara & Haller LLP provided him with a solid foundation in both white-collar criminal defense and civil litigation. As a partner in that highly respected firm, Mr. Haller developed the litigation and negotiation skills that now define his private practice. He handled cases that ranged from federal criminal trials to complex civil disputes, often working on matters where reputational risk and legal exposure were high. Those formative years reinforced the importance of precision, thoroughness, and client advocacy—principles that continue to guide his work today.

Alexis Haller’s admission to practice before the United States Supreme Court and multiple federal appellate courts reflects a level of trust and capability not easily attained.

His legal writing is known for its clarity, logic, and persuasive force, making him a formidable presence in appellate litigation.
His commitment to legal excellence is further reflected in his active participation in professional organizations.

These affiliations ensure that he stays current with changes in both domestic and international law, enabling him to offer informed and effective representation to his clients.
Outside of his demanding legal career, Alexis Haller maintains a strong connection to the outdoors and family life. He often spends weekends hiking through the California hills or catching waves along the Pacific coast. These personal pursuits are not just hobbies—they serve as a grounding force that helps him maintain focus and clarity in his legal work. His enthusiasm for nature and physical activity mirrors the energy and tenacity he brings to his professional practice.
His multifaceted legal career, rooted in exceptional academic preparation and enriched by over a decade of litigation experience, reflects a deep-seated commitment to justice, intellectual rigor, and client service.

Clients who work with Alexis Haller often find that his approach combines analytical precision with a profound sense of responsibility for the outcomes he seeks on their behalf. Unlike many practitioners who treat appellate or international cases as purely academic exercises, Mr. Haller remains deeply aware of the real-world consequences his clients face—whether it's years of imprisonment, financial penalties, diplomatic tensions, or reputational harm. He approaches each matter with empathy, viewing every client as an individual with a story, not just a file number. This philosophy influences how he communicates with clients, always aiming for transparency, thoroughness, and trust-building through every step of the legal process.
His appellate strategy is shaped not only by knowledge of case law but by an ability to anticipate the concerns and priorities of appellate judges. Mr. Haller is particularly skilled at identifying the most compelling legal issues from a record often hundreds or thousands of pages long. He then crafts arguments that balance technical accuracy with a compelling narrative. In criminal appeals, for example, he has persuaded appellate courts to reverse convictions or remand for further proceedings by focusing on procedural violations, evidentiary errors, or ineffective assistance of counsel. His work on habeas corpus petitions further highlights his commitment to justice, especially for those who have exhausted their direct appeal options but still seek relief through post-conviction mechanisms.
In civil litigation, Mr. Haller is known for effectively handling disputes that involve high monetary stakes or sensitive diplomatic matters. Breach of contract claims, fraud allegations, and property disputes often require intensive document review, deposition strategy, and negotiation—all areas where Mr. Haller excels. His clients benefit not only from his litigation experience but from his ability to de-escalate conflicts where appropriate, proposing creative resolutions that align with their long-term goals. Yet when a matter must be resolved in court, he does not hesitate to advocate forcefully and persuasively.
One of Mr. Haller’s most distinctive legal skills lies in managing cross-border disputes. Whether he is navigating a case involving foreign governmental immunity or working on enforcement of judgments involving international defendants, he understands the importance of respecting jurisdictional boundaries while asserting U.S. legal principles. These matters frequently involve interplay between U.S. law and international treaties or conventions—such as the FSIA, the Vienna Convention, or bilateral mutual legal assistance agreements. His fluency in legal systems and cultures beyond the United States helps him to foresee complications and craft proactive legal strategies for clients operating in a globalized world.
Throughout his career, Alexis Haller has earned praise not just for courtroom results, but for the level of preparation and scholarship he brings to every case. His written submissions are known for their clarity and power, which is no surprise given his academic background at Princeton and Stanford—two institutions that instill both intellectual rigor and a capacity for critical thought. While many attorneys can spot legal issues, few can articulate them with the same degree of polish and persuasion that characterizes Mr. Haller’s appellate briefs and trial motions. It’s a skill that frequently tips the balance in high-stakes cases, especially when clarity of argument can make the difference in a close decision.
His participation in elite legal panels further demonstrates the high regard in which he is held by his peers. As a member of multiple Criminal Justice Act appellate panels and state appellate panels, Mr. Haller is regularly appointed to represent individuals who cannot afford private counsel in appellate proceedings. These appointments reflect not only his competence but his commitment to upholding constitutional rights regardless of a client’s financial means. His work in these roles often involves some of the most challenging and important constitutional questions in criminal justice, requiring both a strong grasp of precedent and a passion for fairness.
In every role he undertakes—whether as a legal adviser, appellate advocate, or courtroom litigator—Alexis Haller demonstrates a rare blend of intelligence, strategic insight, and ethical commitment. He is not simply a technician of the law but a principled advocate who believes in the rule of law and the importance of defending it across all levels of the justice system. This outlook informs how he interacts with judges, opposing counsel, and clients alike, earning him respect even from those on the other side of the courtroom.
His work has also contributed to shaping legal interpretations in developing areas of law, particularly those involving the reach of U.S. courts in international contexts. In a legal landscape where the actions of foreign officials, heads of state, and sovereign governments frequently intersect with American legal proceedings, Alexis Haller offers a unique voice—someone who understands both the letter of the law and the subtleties of international diplomacy. His experience representing sovereign defendants in U.S. courts has helped define the boundaries of legal responsibility for foreign states, protecting the integrity of diplomatic relations while ensuring adherence to constitutional safeguards.
Whether helping a client avoid unjust prosecution, defending a foreign dignitary from overreaching discovery, or challenging an appellate ruling before the nation’s highest court, Mr. Haller remains focused on excellence at every turn. His practice is grounded in scholarship, driven by results, and inspired by a genuine desire to uphold the core principles of justice and fairness. As he continues to represent clients in increasingly complex and high-profile matters, Alexis Haller remains one of the most respected and capable attorneys practicing in California and beyond.
What distinguishes Alexis Haller from many in his field is his ability to translate intricate legal doctrines into meaningful, strategic action. This skill is especially vital when dealing with cases that hinge on technical procedural issues or highly specialized areas such as the Foreign Sovereign Immunities Act. Many legal professionals may understand the statute in theory, but Mr. Haller has lived its nuances in courtrooms, securing dismissals and shaping precedent through direct litigation. His involvement in these cases reflects not only his legal aptitude but also a finely honed instinct for which arguments will resonate with courts at every level—from trial benches to federal appellate panels and the U.S. Supreme Court.
The success Mr. Haller has achieved in these complex arenas is not accidental. It stems from a career built methodically over years of experience and rigorous preparation. At Swanson, McNamara & Haller LLP, he gained hands-on exposure to high-stakes litigation early on, rapidly rising from associate to name partner. His contributions during this time involved challenging some of the most sensitive evidence in federal criminal trials and formulating sophisticated defenses for clients accused of serious financial and white-collar crimes. The legal strategies he developed during these years continue to inform his current practice, allowing him to approach modern litigation challenges with the benefit of deep institutional knowledge and tactical finesse.
His continuing role in appellate panels for federal and state courts has reinforced his commitment to excellence in legal writing and oral advocacy. These panels are composed of attorneys recognized for their skill and ethical standards, and being selected to participate is a clear acknowledgment of Mr. Haller’s standing in the legal community. Through this work, he has helped shape legal interpretations across a range of issues, from criminal sentencing to evidentiary admissibility, all while representing some of society’s most vulnerable defendants—those who would otherwise face the system alone.
Alexis Haller’s multilingual abilities are another key strength in his international practice. Fluent in French, proficient in Italian, and conversational in Spanish, he is able to communicate directly with international clients and legal counterparts without intermediaries. This facilitates more efficient case preparation and enhances trust between parties, especially in sensitive diplomatic or governmental cases. Language fluency also allows him to review legal documents and treaties in their original forms, ensuring that no nuance is lost in translation—a valuable asset in international litigation where the smallest misinterpretation can alter the course of a case.
Even in highly adversarial litigation, Mr. Haller maintains a standard of professionalism and civility that commands respect. Judges and peers alike recognize him as a thoughtful, well-prepared, and courteous advocate. He believes that the practice of law should uphold the dignity of the courtroom and the integrity of legal institutions, even when emotions run high or stakes are enormous. This approach not only benefits his clients but strengthens the credibility of their cases in the eyes of the judiciary.
Alexis HallerHis academic achievements provide a strong foundation for his legal excellence. At Princeton University, Alexis Haller earned summa cum laude honors and was inducted into Phi Beta Kappa, the nation’s oldest academic honor society. His leadership role as president of the American Whig-Cliosophic Society—one of the country’s oldest college debating forums—reflected an early commitment to public discourse and critical thinking. At Stanford Law School, he built upon this foundation, mastering both doctrinal analysis and legal writing, two skills that would define his career in the years to come.
While the breadth of Mr. Haller’s legal work is impressive, it is perhaps his consistency that most defines his reputation. Regardless of the client—whether a wrongfully convicted individual, a foreign dignitary, or a corporation facing cross-border legal exposure—he delivers the same high level of strategic insight and legal care. He sees each representation not simply as a professional obligation, but as a personal commitment to justice, fairness, and excellence. This ethos permeates every part of his practice, from initial consultations to final appellate submissions.

His clients benefit from a lawyer who not only understands the law at its most intricate levels but who can apply that knowledge effectively and with purpose. Whether advocating in a U.S. courtroom or addressing legal issues that span continents, Alexis Haller continues to serve as a leading figure in litigation and appellate law.
Clients and colleagues alike often remark on Alexis Haller’s thoroughness—a trait that extends beyond case law to encompass every detail of the litigation process. From the moment he takes on a case, he immerses himself in the facts, legal theories, procedural posture, and jurisdictional contours. He understands that in appellate and international matters, success often turns on the smallest overlooked point: a misapplied precedent, an improperly preserved objection, or a subtle inconsistency in witness statements. His diligence ensures that no viable argument goes untested, no angle unexplored. For clients, this means confidence that their representation rests on a complete and uncompromising review of their legal position.
In appellate practice, where the outcome hinges less on persuasion of juries and more on precise legal reasoning, Alexis Haller’s talents are particularly pronounced. He has a gift for distilling dense trial records into persuasive, tightly argued briefs that engage the appellate bench without unnecessary complexity. Judges tasked with reviewing hours of transcripts and thousands of pages appreciate his ability to crystallize the crux of the matter. Whether drafting a petition for certiorari to the U.S. Supreme Court or filing a direct appeal in the California Court of Appeal, Mr. Haller brings the same careful attention to organization, tone, and clarity that sets his written advocacy apart.
His work in habeas proceedings and post-conviction relief reflects a parallel strength: the ability to blend legal mastery with a human-centered approach. These cases often involve clients who have exhausted most or all traditional remedies and now seek justice through more technical legal paths. For many, Mr. Haller represents not only their last chance at relief but also the first attorney to take their story seriously. He combs through court records, interviews, and trial transcripts to find legal errors, constitutional violations, or ineffective assistance that might form the basis for reopening the case. In doing so, he offers more than legal support—he offers hope backed by tenacity and skill.
In the civil litigation sphere, particularly within the framework of the Foreign Sovereign Immunities Act (FSIA), Mr. Haller’s track record continues to draw attention. He has successfully defended foreign sovereigns and their representatives against jurisdictional overreach, unlawful discovery demands, and attempts to circumvent diplomatic protections. These cases often carry both legal and political implications, requiring deft handling of sensitive communications, intergovernmental protocols, and the nuances of international law. By representing clients in these contexts with discretion and strategic precision, Mr. Haller has developed a reputation not only for legal excellence but for being a trusted figure in the delicate intersection of law and diplomacy.
Moreover, his willingness to assist other attorneys on complex motions and filings demonstrates a collaborative spirit rarely seen among litigators at his level. Whether he’s consulted on a major evidentiary motion in a criminal case or asked to co-author an amicus brief in an appellate matter, he brings intellectual rigor and a fresh strategic perspective. This kind of collaboration helps elevate the legal work of others while enriching his own understanding of the broader legal landscape. His name often appears behind the scenes on some of the most consequential pleadings in state and federal courts, a quiet testament to how frequently he’s sought after by peers for his expertise.
Alexis Haller’s commitment to continuous legal education also keeps him at the cutting edge of evolving legal standards. He follows updates in statutory law, judicial interpretation, international agreements, and procedural rules with the kind of discipline that reflects both passion and professionalism. This ongoing engagement allows him to anticipate legal trends and changes before they become widely discussed, giving his clients a strategic edge. His multilingual abilities also allow him to review foreign legal sources in their original languages—an advantage in international law rarely matched by U.S.-based litigators.
In a world where legal disputes are increasingly international and appellate decisions shape the direction of public policy and individual lives alike, attorneys like Alexis Haller play an essential role. His ability to blend advocacy, scholarship, and diplomacy has positioned him as a powerful ally to those navigating complex, high-stakes legal terrain. Through meticulous preparation, persuasive argument, and unwavering commitment, he continues to offer clients not just legal representation but the confidence of knowing that every possible advantage is being pursued on their behalf.
Equally notable is the personal attention Alexis Haller provides to each case he takes on. In a legal world often dominated by large firms and impersonal hierarchies, his boutique practice offers something increasingly rare: direct access to the attorney actually crafting and arguing the case. Clients are never shuffled between junior associates or handed off to paralegals for critical stages of their litigation. Instead, Mr. Haller remains hands-on throughout, ensuring that every filing, every hearing, and every argument reflects his own high standards. This level of personalized service is especially important in appellate and international litigation, where continuity of strategy and voice can mean the difference between success and failure.
Mr. Haller’s approach also reflects a deep respect for the rule of law. Whether he is defending a foreign head of state from litigation in U.S. courts or advocating for a wrongfully convicted individual seeking post-conviction relief, his work is grounded in a firm belief in constitutional protections, procedural fairness, and judicial integrity. He views the law not merely as a tool for advocacy but as a framework that demands rigor, balance, and responsibility. This perspective has earned him the trust of judges, opposing counsel, and clients alike. It also informs the way he mentors younger attorneys and collaborates with colleagues across jurisdictions.
His licensure in multiple bars—including California, Washington, and the District of Columbia—further broadens the scope of matters he is able to take on. Whether a case originates in a state court in California or moves through federal appellate circuits such as the Second, Sixth, Seventh, or Ninth, Mr. Haller is prepared to handle it seamlessly. His admission to practice before the United States Supreme Court places him among the select group of attorneys capable of shepherding a case through every level of the American judicial system. This makes him a valuable legal partner for clients who anticipate multi-tiered litigation or who need consistent representation across multiple forums.
Outside the courtroom, Alexis Haller remains active in the legal community through his affiliations with professional organizations such as the American Bar Association and the American Society of International Law. These memberships not only keep him informed on developments in domestic and international jurisprudence but also connect him to a network of thought leaders and specialists around the world. This global perspective informs his casework and allows him to navigate transnational legal issues with confidence and cultural competence—particularly important when diplomatic sensitivities or international treaties are involved.
Away from legal work, Mr. Haller leads a balanced and intellectually curious life. He is an avid reader with a particular interest in history and global affairs—interests that no doubt shape his nuanced understanding of legal context and international dynamics. He enjoys spending time outdoors with his family, often hiking the California coast, skiing in the mountains, or surfing the Pacific. This connection to nature, along with his enduring love for family life, adds a human dimension to his practice. Clients working with him are often struck not just by his legal acumen but by his grounded, approachable demeanor.
What further enhances Mr. Haller’s effectiveness is his rare combination of appellate skill and trial-level experience. While many attorneys specialize in only one forum, his comfort in both trial courts and appellate benches gives him an uncommon versatility. He knows how to craft trial motions with an eye toward eventual appellate review, and he understands how to frame appeals in ways that respect the trial court record while introducing fresh legal perspectives. This dual fluency helps him anticipate challenges before they arise and pivot strategy when necessary—always with an eye toward long-term resolution rather than short-term wins.
