"Thank you Mike Sena and Justin Miller for your assistance with helping us get the appropriate coverage for our home and autos. After reviewing our existing coverage, it was pretty obvious that we were under insured. Justin explained the potential deficiencies with our current policies and provided recommendations to correct them. Again, thank you both for taking the time and having the patience to help us get the coverage we needed. I will gladly recommend you to my friends and acquaintances."

"I worked with Steve Rodriguez and he was wonderful! He was great about getting back to me quickly about my questions. He made sure to work with my schedule when planning to talk about my insurance. He broke down my whole coverage and did an exceptional job of explaining anything I did not understand. He was great and easy to talk to and I never felt like I was being judged for my many of silly questions."

"I got a call from Caitlin at State Farm seeing if they could have me back as a customer. I wasn’t interested but she asked if she could get me a free quote just to compare. It only took a few minutes and she was able to get me a better policy at an even better price. She was nice and easy to work with. Glad to be back with State Farm saving money"
