Founded in 1887 as W.S. Troxell, Troxell is today one of the largest independent insurance agencies in Illinois. Just this year, Troxell rebranded after a century of being named R.W. Troxell after the founder’s son, who purchased the agency in 1905.
Currently serving more than 4,300 commercial clients, Troxell offers a variety of insurance solutions, including industry specialties in nine different sectors such as education, hospitality and nonprofits. The firm places more than $200 million in premium annually and boasts a 90% client retention rate. Most recently, Troxell opened a new division, Insurance Risk Managers, which launched in October 2016.
