"Worked with Justin. He was a joy to work with. Easy to talk to, but most importantly, he asked detailed questions and made sure that I was not under insured. He also provided a quote quickly and accurately. The quote, which had great coverage was about $1000 cheaper than competitors. Great bundling discounts. Highly recommend."
We responded:
"Thanks for sharing your experience! Justin cares deeply about ensuring the right coverage and saving you money. We’re happy he could deliver great service and value. - Greg Kostuk State Farm"

"Zach (Not Jake!) at StateFarm has helped me probably more than anybody else in a time that I needed reassurance and an affordable coverage the most. Not only that but the impression I received the whole time was honest and genuine. I’m paying less for insurance, I have the coverage I need right now, and there was no hidden fees or policies that I was made aware of. Everything worked out as I needed it too. Thank you very much Zach for helping me get the coverage I needed without the hassle."
We responded:
"Thank you for your wonderful review! Zack is committed to making sure every customer feels supported and informed. We’re glad you’re satisfied with your coverage and pricing, and we appreciate your trust in us! - Greg Kostuk Insurance Agency"

"Have had a great experience so far with this State Farm branch. After some sneaky behavior by my previous Farmers agent, it was nice to return to State Farm and feel as if they would be looking out for my best insurance interests. In particular, Jacob Turbett was wonderful in answering a slew of questions last November when I was looking to change insurance. Personable and clear on coverage explanations."
We responded:
"Thank you for trusting us with your insurance needs once again. It’s wonderful to hear that Jacob was able to assist you with such professionalism and clarity. We’re committed to ensuring our customers always feel supported and informed, and your feedback means a lot to our team! - Greg Kostuk Insurance Agency"

"Look, there’s boys, there’s men, and then there’s Justin. Not all hero’s wear capes, but Justin deserves one. Saved me nearly 250 a month. He saved my marriage, my dogs, my life. Honestly with the money I saved per month I’ll probably build a statue of Justin in my yard. Okay on a more serious note he was very helpful, calm and well put together. He listened to my needs and was willing to talk me through things even if it took me a minute to understand it. I would highly recommend calling them and seeing if Justin can help you out, I know he really did save me 250ish a month, same coverage and added a little."
We responded:
"We’re beyond grateful for your amazing feedback! Justin truly goes above and beyond to make sure our clients feel supported and understood, and it’s wonderful to hear how much of a difference he made in your life. Thanks for recommending us, and please don’t hesitate to reach out if you need assistance in the future! - Greg Kostuk Insurance Agency"

"We cannot say enough great things about working with Justin Miller! As first-time homeowners, we had a lot of questions and honestly felt overwhelmed by the insurance process, but Justin made everything so clear and easy to understand. He walked us through our options, explained what coverage actually matters, and was incredibly responsive every step of the way. What really stood out was how much he genuinely cared about making sure we felt comfortable and confident with our decisions, never rushed, never pushy, just truly helpful and kind. We feel so lucky to have worked with him and would recommend Justin to anyone looking for an insurance agent who is knowledgeable, trustworthy, and great to work with."
