Dallas

Many of Sidley’s Dallas-based practices and lawyers are recognized as leaders in their respective fields. Recently, our Litigation group was recognized by Chambers USA as Band 2 and as a Finalist for Regional Litigation Department of the Year – Texas by The American Lawyer. Sidley’s Dallas Litigation group consistently produces winning results for clients in a wide-range of litigation and arbitration matters, as well as exhibiting unparalleled skill in handling the most sensitive of corporate investigations for clients who need real world advice on their most complex business problems. The Dallas group is formidable, with nearly 50 litigators and Chambers-ranked lawyers in commercial, securities, white-collar, intellectual property, and employment litigation.

Sidley’s premier transactional team helms significant deals in Texas and is consistently recognized among the leading practices in the state. Most recently, The Texas Lawbook’s M&A Corporate Deal Tracker ranked Sidley #2 in overall deal count for Texas transactions, with 151 deals completed in 2022, up from 138 deals in 2021. By lawyer headcount, that is more deals per lawyer than any other firm in Texas. With determination and a stellar list of clients that define the region and globally alike, the firm has become the go-to Texas firm for the highest-stakes transactions.

Our lawyers are also consistently recognized by Chambers USA, The American Lawyer, Law360, Texas Lawbook, Best Lawyers, Benchmark Litigation, and D Magazine.

Sidley’s commitment to pro bono representation and involvement in the community is a longstanding Texas tradition. Last year, Dallas lawyers dedicated more than 4,900 hours to more than 160 pro bono matters serving those without access to legal services. We are engaged in matters ranging from gaining access for veterans to military and VA benefits to protecting constitutional rights and civil liberties. Sidley provides diverse pro bono services to address the critical legal needs of the firm’s neighbors in the Dallas community, and we value the recognition received in response to our pro bono activities. Recently, the Dallas office was honored by the State Bar of Texas at the 2022 Pro Bono Excellence Awards by receiving the W. Frank Newton Award which recognizes Sidley’s long-standing partnership with the Dallas Volunteer Attorney Program as well as the firm’s Veterans Advocacy Program.

The Dallas office is co-managed by Angela Zambrano and Scott Parel. Angela co-leads the firm’s Commercial Litigation and Disputes group and leads the Dallas litigation group, and Scott is a co-leader of the firm’s Private Equity practice. Together, they manage one of Sidley’s fastest growing offices and continue to focus on providing the highest quality legal advice and talent across wide-ranging legal services and industries.

Yvette Ostolaza, one of the country’s leading business litigators, is Sidley’s Management Committee chair, an Executive Committee member and resident of the Dallas office. She officially took the helm in May 2022 after managing the Dallas office for eight years. Yvette is the first-ever female and Latina chair and the first Texas-based partner to lead the firm.

Sidley’s Dallas office is also home to numerous firm leaders for key national practice and industry groups, including: Aviation (Bart Biggers), Litigation (Yvette Ostolaza/Angela Zambrano), Global Finance (Angela Fontana), Private Equity (Scott Parel), FinTech/Blockchain (Lilya Tessler), and Securities and Shareholder Litigation (Yolanda Garcia).
