Your business. Your employees. Your peace of mind. At Sentry, they understand what matters most to you. Because they've been there themselves. Founded in 1904, when members of the Wisconsin Retail Hardware Association formed their own insurance company. Establishing the company gave members the strength of numbers, but it was the true strength of personalized care and Midwest roots that became hallmarks of the Sentry name. Today, they’ve grown to become a member of one of the largest and most financially secure insurance groups in the country by never forgetting where we came from. Or why. Perhaps that’s why many of our about one million customers have been with us for decades.
