"Steve had a lot of knowledge about coverages and was very friendly while on the phone. He was very patient while speaking to me as I was busy with my kids at the same time. Would recommend him and his team to any of my friends and family!"

"Steve was such a delight to work with. He explained everything in such a detailed manner and got me the best quote, i was speechless. I had been with progressive since 2019 and they were good to us just very expensive. So the fact that my price for state farm was about 300 dollars cheaper than what we were paying of course i had to take the opportunity to switch over. Customer service was top tier and conversation with Steve was as if i was talking to someone id known for years LOL. We will see how good state farm is moving!"

"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."
