WTW (operating globally under its historic brand lineages as Willis Towers Watson) has been operating as a premier global advisory, broking, and solutions enterprise for nearly two decades under its current combined identity, while tracing its deep underlying corporate roots back nearly two centuries. The enterprise's rich history incorporates legendary predecessor firms like Willis, founded in London in 1828, and Towers Perrin, established in the late nineteenth century. Following the landmark multi-billion-dollar merger between Willis Group Holdings and Towers Watson in 2016, the combined publicly traded corporation has spent over a decade delivering comprehensive risk management, insurance brokerage, human capital consulting, and retirement advisory services to clients worldwide.
