In the dynamic and demanding world of corporate law, the firms that stand out are those that go beyond just delivering legal expertise. They excel in client service, a critical metric, especially in an era marked by rapid policy shifts and challenging economic conditions. In 2025, BTI Consulting Group's annual Client Service A-Team ranking highlights the law firms that have mastered this art, proving themselves as the stalwarts in serving corporate counsel across various demanding parameters.

The ranking, which is keenly anticipated each year, is the result of extensive surveys conducted with over 300 in-house decision-makers. These professionals are tasked with evaluating law firms based on 17 vital client service activities. These include quickly mobilizing resources, assembling top-tier teams swiftly, understanding the client’s business deeply, and a strong commitment to delivering value.

This year’s list saw DLA Piper ascend to the top, a notable achievement as it edged out previous leader Kirkland & Ellis. The accolade speaks volumes about DLA Piper's dedication to maintaining robust client relationships and its agility in navigating the complex legal landscape marked by President Trump’s flurry of executive orders and policy changes early in the year.

Other firms that have consistently demonstrated top-tier client service include Jones Day, McGuireWoods, Morgan Lewis, and Skadden. These firms celebrate a decade of consecutive appearances in the top 30, underscoring their long-term commitment to excellence in client service.
