Sidley Moves to Recently Completed 23Springs Tower in Uptown Dallas

The new office opens on the top four and a half floors to accommodate growth as the firm celebrates 30 years in the market

Dallas – Sidley, a 160-year-old elite global law firm with 21 offices across four continents, is pleased to announce the move of its Dallas office to 23Springs. The firm increased its footprint by over 60% and leased 118,484 square feet across the top four and a half floors of the Class AA office tower in the heart of Uptown that was completed last fall. Sidley’s Dallas office has grown to over 200 lawyers and business professionals since its opening in 1996 and currently serves over 2,600 clients on a broad range of high-profile litigation, transactional, and regulatory matters.

“Growing our footprint and relocating to 23Springs reflects our longstanding commitment to Dallas,” said Yvette Ostolaza, Sidley's Management Committee Chair. “Dallas is a key market for Sidley and a hub for our leading Commercial Litigation and Disputes, FinTech, Global Finance, Healthcare, Private Equity, Restructuring, Tax, and White Collar Defense and Investigations practices. We remain focused on strategic growth by continuing to expand our team and presence in this critical region.”

“2026 marks our 30th anniversary in Dallas and it’s fitting that we open our doors in the premier office project in the Uptown area,” shares Scott Parel, co-managing partner of the Dallas office and co-leader of the firm’s Private Equity practice. “Our new home in 23Springs will support our rapid growth and greatly enhance the workplace experience for our lawyers and business professionals for years to come.”

“This office is more than simply a place to work, it’s a strategic investment in how we collaborate, engage with clients, and cultivate innovation,” adds Angela Zambrano, co-managing partner of the Dallas office, member of the Executive Committee, and co-leader of the firm’s global Litigation practice. “The space is designed to expand our practice across key industries, integrate and nurture top talent, and meet the increasingly sophisticated needs of our diverse global client base.”

Key highlights of the new office include:

• Located on the top floors of the building with a private landscaped terrace that offers sweeping views of Uptown and Downtown Dallas.
• Elevated conference facilities that feature state-of-the-art technology and client amenities, including a 50-person boardroom, transitional event space, virtual court and board room settings, and an in-house broadcast studio.
• Redesigned practice floors boasting warmth and natural light that provide alternative work and meeting spaces with a hospitality forward approach.

The newest commercial building in Uptown, 23Springs offers exceptional access to the Central Business District and nearby cultural and entertainment hubs, including the Dallas Arts District, Victory Park, the West End, Deep Ellum, and the Design District. The building features a dramatic two-story lobby with an elevated coffee-and-wine bar, along with a first-class conference center, high-end fitness studio, upscale lounge with wine lockers and a golf simulator, outdoor meeting spaces, six levels of underground parking, and sweeping views of the Uptown and Downtown skyline. The lobby also features the largest interactive indoor video wall in Dallas that wraps a corner and responds to people as they approach or walk past.
