What is the largest injury law firm in the world?

Sometimes "the biggest" personal injury firm could be measured using different factors - number of attorneys, annual revenue, number of cases handled, etc. Some of the top injury law firms in the United States in terms of size could include Morgan & Morgan, Cellino & Barnes, and Slater Slater Schulman. Yet internationally, there sometimes may be bigger companies too. Choosing the right personal injury attorney can be crucial, especially when dealing with large firms that have a wide reach across multiple states.
Morgan & Morgan is assumed to be one of the largest damage law firms of the USA. Florida-based firm with more than 500 attorneys covering 50 offices in nearly 50 states throughout the US. They cater to all types of tort cases whether it is an individual injury or mass torts.
The law firm Slater Slater Schulman was established in 1995, but it has headquarters in New York. Having built up their reputation as a leading plaintiff litigation company, they have been handling complex mass torts, medical malpractices, products liability and catastrophic injuries for a while.
Cellino & Barnes was incorporated in 1958 and it is known for being one of the prominent legal practices in New York in the field of personal injuries. At the end of the day that had somewhere close to 750 people employed in 7 offices - in NYC and CA. Hence, the firms's name was changed, and it split in 2017 to become two independent firms.
