"So last night I received a call from Justin asking me if I received everything I needed from the phone call I had left last I think it was 2 weeks ago requesting information on insurance for my new car. Up until last night I had not heard anything from your office so I had previously gone with another insurance company to provide insurance for my new car. I have been previously upset because I have my motorcycle insurance through you guys and I wanted to keep it all the same. Justin asked me if I would like a quote from my new car. He was very friendly kind and explained everything I needed to know about my insurance the quote was almost $200 cheaper than the amoun I was going to pay through other insurance company. I'm so glad that he reached out so glad that I'm still utilizing State farm and it's all because Justin took the initiative to reach out and see if there was anything he could still help me with. I think that $100 gift card is a little low for someone who worked as hard as he did to provide the type of quality Care that needed to be done in order to get my business back with you guys. Thank you Justin you're amazing. And thanks for showing the rest of your team how customer service is done.!!"
We responded:
"Ursula, thank you for sharing this. We are glad Justin followed up on your new car insurance request and walked you through the quote with care. His initiative and care mean a great deal, and we appreciate you choosing State Farm again. We look forward to earning your trust and a 5th star!

"i spoke to an agent named Jacob and he quoted me for my auto and renters, although the price was not cheaper he was the nicest agent i’ve spoken to in a while! He let me know he will be contacting me when my next renewal comes up and i hope the price aligns with having him as my agent one day! He did an amazing job at breaking down my coverages and the other products they offer like life insurance!"
We responded:
"Thank you, Joey, for the fantastic review. We are so glad to hear that Jacob was able to help you better understand your coverages for Auto, Renters, and Life Insurance. We hope to work with you in the future!

"I had such a great experience working with Jacob! He was incredibly knowledgeable, professional, and helpful throughout the entire process. He took the time to explain everything clearly, answered all of my questions, and made sure I felt comfortable with my options. He was also able to find me a rate that was significantly cheaper than what I was currently paying for insurance, which was a huge plus! You can tell Jacob genuinely cares about helping people and knows his stuff when it comes to insurance. I would definitely recommend him to anyone looking for someone trustworthy, knowledgeable, and easy to work with!"
We responded:
"Rachel, thank you for the amazing review! We are so glad to hear that working with Jacob was clear and helpful. Finding a great rate while ensuring that you understand your coverages is what we strive for!
