"This was a great experience for me. Kody helped me a lot with information about insurance and options I have in California as a young adult with a limited budget. We went over different discounts such as multi-line and loyalty. He explained how Prop 103 was affecting the current market and was very knowledgeable about the industry."

"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."
