"To say that my expectations were exceeded would be an understatement. Gus with Justin Costello’s office was the first person from an insurance company to simplify and explain things to me so that I could understand my own coverage and what I was paying for. He also went above and beyond to become a friend, was interested what I had going on in my life, and made sure that I truly had the best ( and most affordable) coverage that fits my situation. Five stars isn’t enough!!!"

"Signed up in 2023 after meeting with Gus, a knowledgeable, personable guy. I had never bundled before but so glad I did. Saved me a lot of money. Just this week met Justin. He called me to come in and wasn't sure why but glad I did. He explained a lot about raising rates I didn't know plus went over my policy to see if changing anything would help reduce costs. These people really care!!"

"I spoke with Kody Green about getting my auto quoted. He was very friendly and informative throughout the process. He was able to answer all of my questions thoroughly and explain with hypothetical scenarios what coverage I would be getting. He also dove into great detail about changing state minimum coverage requirements from this year to the next. His explanations made me feel very comfortable about available options. Overall, I had a great experience getting quoted with him and I felt confident/knowledgeable on exactly what type of coverage I was purchasing. I would highly recommend him to anyone looking to purchase insurance."
"Alex, I am happy to hear you such a positive experience with Kody! Thank you for leaving such a great review."
