"There is a reason I've had State Farm for 50 years: great service, especially when I have a claim. Anyone can save me a few bucks in rate, but State Farm is a bulldog with other insurance companies and has saved me thousands of dollars. When I moved to Colorado my former agent in Illinois recommended Greg, and I have gotten the same great service from his team"

We’re honored to hear that our great service, especially during claims, has kept you with us—and that our team at Greg Kostuk Insurance Agency has lived up to that standard since your move to Colorado. We take pride in being your bulldog, saving you thousands while fighting for what’s right.
