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 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.

Justin has been great to work with! He set me up with the coverage I needed quickly and continues to respond promptly to needs as they have arisen after all policies were in place. I highly recommend working with this office!

Amber Cantu did a great job! She was professional, friendly, and made the whole experience smooth from start to finish. Her customer service skills are excellent — she really takes the time to listen and make sure everything is done right. Highly recommend working with her!

This specific office is extremely professional, knowledgeable, and ethical. After being helped by Mike Sena, I felt genuinely cared for and very well informed on how to make a custom auto policy that would provide me the best coverage and save me the most money. Mike is great at demystifying insurance in an accurate and concise manner. I also was able to save a ton relative to my previous policy. If you need someone to who is knowledgeable, polite and interested in tailoring an auto policy directly to you, call the Kostuk State Farm office and ask to work with Mike.
