Joshua A. Block is an American civil-rights attorney and Senior Counsel with the American Civil Liberties Union’s LGBTQ & HIV Projects, known for litigating major cases involving LGBTQ rights, transgender rights, marriage equality, free expression, employment discrimination, healthcare access, and military service. His legal career has placed him at the center of several significant federal cases, including United States v. Windsor, Obergefell v. Hodges, and Grimm v. Gloucester County School Board. Block has also appeared in litigation concerning transgender military service and healthcare and has contributed to legal education through his work as a visiting lecturer at Yale Law School. Although much of his professional life is documented through court records and institutional biographies, he keeps many aspects of his personal life private.
Who Is Joshua A. Block?
Joshua A. Block is a civil-rights lawyer whose career has been closely associated with constitutional and statutory litigation concerning LGBTQ people. He is Senior Counsel with the American Civil Liberties Union’s LGBTQ & HIV Projects, where his work has included cases involving transgender students, same-sex marriage, military service, healthcare, employment discrimination, religious objections to LGBTQ rights, and freedom of speech. The ACLU identifies Block as a member of the legal teams that litigated United States v. Windsor and Obergefell v. Hodges before the U.S. Supreme Court. His work has also included Grimm v. Gloucester County School Board, a case involving a transgender student’s access to school restrooms. Court records identify Joshua A. Block as counsel for Gavin Grimm, while the ACLU describes the litigation as producing an important federal appellate ruling concerning Title IX and transgender students. Unlike public figures whose biographies focus heavily on entertainment or personal milestones, Block’s public profile is predominantly defined by legal advocacy, court appearances, written briefs, and institutional work.
Background in Civil-Rights Law
Joshua A. Block’s legal background combines private-practice litigation, federal appellate work, judicial clerkship, and nonprofit civil-rights advocacy. He graduated from Amherst College in 2001 and Yale Law School in 2005. After law school, he clerked for Judge Robert D. Sack of the U.S. Court of Appeals for the Second Circuit. He subsequently worked as a litigation associate at Jenner & Block LLP in New York from 2006 to 2010, handling complex commercial litigation, internal investigations, white-collar defense, and appellate matters, including work before federal appellate courts and the Supreme Court. In 2010, he joined the ACLU’s LGBTQ & HIV Project. This progression gave Block experience across several forms of litigation before he moved into a specialized civil-rights practice. His professional biography also records an academic connection with Yale Law School, where he served as a Visiting Lecturer in Law and taught an LGBT Rights Litigation Seminar.
Marriage or Relationship with His Husband
Publicly available information about Joshua A. Block’s marriage is limited compared with the extensive documentation of his legal career. A Charles E. Smith Jewish Day School alumni profile published in 2021 identified Block as living with his husband and their two children at that time. The profile is useful for confirming the existence of his family relationship, but it does not establish his husband’s identity through the kind of authoritative biographical source normally used for detailed celebrity profiles. Accordingly, his husband’s name should not be added to a biography as fact without stronger public documentation. Block has generally maintained a professional public profile, with institutional biographies concentrating on his education, litigation, teaching, and civil-rights work rather than providing extensive information about his marriage. This distinction is important for an accurate biography because publicly available family information should not be expanded through assumptions or material from unreliable sources.
Parenthood and Family Life
Joshua A. Block is publicly reported to be a parent of two children. The 2021 alumni profile from Charles E. Smith Jewish Day School stated that he lived with his husband and two children, then described as ages seven and two. Those ages were accurate only at the time of publication and should not be treated as their current ages. There is limited reliable public information about Block’s children, including their names, education, current locations, or later life. That lack of information appears consistent with a deliberate separation between his professional public role and his family’s private life. For a biography focused on E-E-A-T and factual reliability, it is therefore more appropriate to acknowledge the publicly documented family structure without attempting to identify or profile family members who do not have a substantial public presence of their own.
Advocacy Through Major LGBTQ Rights Challenges
A defining part of Joshua A. Block’s career has been his involvement in litigation addressing the legal rights of LGBTQ people. His work on United States v. Windsor and Obergefell v. Hodges placed him on legal teams involved in two major Supreme Court cases concerning same-sex marriage. The ACLU also identifies him as lead counsel in Grimm v. Gloucester County School Board, which concerned a transgender student’s ability to use a school restroom consistent with his gender identity. The Grimm litigation eventually produced a 2018 federal district court ruling allowing the case to proceed, and Block continued to appear as counsel in subsequent proceedings. Block’s work has not been limited to education or marriage. He has also litigated matters involving transgender military service, access to healthcare, employment discrimination, censorship, free speech, and religious objections to LGBTQ protections. The range of these cases demonstrates the breadth of his civil-rights practice rather than a career confined to one legal issue.
Life Beyond Landmark Litigation
Block’s public legal work has continued beyond the cases that established his earlier reputation. In 2017, he was involved in Stone v. Trump, litigation challenging restrictions on transgender people serving in the U.S. military. The federal district court granted a preliminary injunction that halted implementation of major aspects of the policy while the litigation proceeded. The case was later listed by the ACLU as closed, reflecting the conclusion of that particular litigation rather than an end to Block’s broader legal practice. His later work has included litigation concerning healthcare for transgender people. In February 2025, the ACLU, Lambda Legal, ACLU of Maryland, and other organizations filed a federal challenge concerning a Trump administration executive order affecting gender-affirming healthcare for people under 19, with Block listed among the attorneys. A federal judge subsequently issued a temporary restraining order blocking enforcement of the challenged policy. In 2024 and 2025, Yale Law School also featured Block in discussions concerning the legal landscape surrounding gender-affirming healthcare and the Supreme Court’s United States v. Skrmetti decision.
Career Highlights and Public Recognition
Joshua A. Block has received professional recognition for his work in LGBTQ law. In 2012, the LGBT Bar Association named him among its “Best LGBT Lawyers Under 40,” an honor reported by contemporary coverage of the organization’s awards. His legal career has also received broader public exposure through The Fight, a documentary about ACLU lawyers litigating several major cases during the Trump administration. The documentary followed Block and fellow ACLU attorney Chase Strangio in their work challenging the transgender military policy. His court record provides another measure of his professional role. In the Gavin Grimm litigation, a federal court filing concerning attorney fees stated that Block had served as lead counsel through every stage of the proceedings, drafted major memoranda and briefs, and presented oral argument before both the district court and the Fourth Circuit. In more recent years, the ACLU has continued to identify him as Senior Counsel, and in 2025 he was publicly involved in Supreme Court litigation concerning challenges to restrictions on transgender students’ participation in school sports.
Why People Search for Joshua A. Block
People search for Joshua A. Block for several overlapping reasons, with his name appearing in connection with major U.S. civil-rights cases, the ACLU, Yale Law School, and transgender-rights litigation. His participation in Obergefell v. Hodges and United States v. Windsor connects his career to Supreme Court litigation over same-sex marriage, while his role in Grimm v. Gloucester County School Board connects him to a nationally significant dispute over transgender students and Title IX. Searches for his name can also arise from his work challenging restrictions on transgender military service and healthcare. In 2025, his name appeared in federal litigation concerning a presidential executive order affecting healthcare for transgender people under 19, while his Supreme Court-related work also included cases challenging restrictions on transgender students’ participation in athletics. His academic connection to Yale Law School adds another reason for interest, particularly because he has both graduated from the school and subsequently taught there.
Privacy, Accuracy and Public Information
Much of Joshua A. Block’s biography can be established from institutional biographies, court filings, university publications, and contemporaneous reporting, but several personal details remain undisclosed or insufficiently documented. Reliable sources reviewed for this article do not establish his birth date, birth year, birthplace, current home address, personal net worth, or his husband’s name. The ACLU biography focuses on his legal career, while a 2021 school alumni profile provides limited family information. It is also important to distinguish between Block’s own statements and descriptions published by organizations representing him professionally. For example, the ACLU describes his litigation as protecting transgender rights and identifies specific legal milestones, while court records independently establish his appearances as counsel. A trustworthy biography should preserve that distinction instead of presenting institutional characterizations as independent judgments. As of 2026, the ACLU’s official biography identifies Joshua Block as Senior Counsel in its LGBTQ & HIV Projects, providing the clearest current description of his professional position.
Conclusion
Joshua A. Block has built a legal career around complex civil-rights litigation, with publicly documented involvement in major cases concerning marriage equality, transgender students, military service, healthcare, free expression, and other LGBTQ-related issues. His path from Amherst College and Yale Law School through a federal judicial clerkship and private litigation practice to the ACLU illustrates a progression toward specialized appellate and constitutional advocacy. His public record is particularly notable for his participation in Windsor, Obergefell, Grimm, and Stone, as well as later litigation concerning transgender healthcare and participation in school athletics. At the same time, relatively little verified information is available about his private life, and his family has largely remained outside his professional public profile. For readers researching Joshua A. Block, the most reliable picture is therefore that of an experienced American civil-rights attorney whose professional work has intersected with some of the most consequential LGBTQ-related legal disputes in the United States.
