"I’ve been with State Farm 40+ years. I started with their car insurance, then added home coverage. They beat my previous car insurer on price back then, and to this day I have not been able to find anyone who’ll cover me for less. More importantly, though, is that my agent, Diane Sinner, always takes care of me. Claim issues, billing issues, coverage questions, you name it - her office is helpful. When I recently called to adjust my coverages, they walked me through what would and wouldn’t be covered in the new scenario, what the difference in premium would be, where I could save a few dollars if that’s what was really important, etc. It’s so much nicer to work with them than an insurance company with only a call center as my point of contact."
"Hi Michael,
Thank you so much for your kind words! They are truly appreciated. We are glad to continue to help you with your home and auto insurance needs. We enjoy reviewing coverages with everyone!!
Our best!

"I have used Sinner’s office for almost 21 years. They have taken impeccable care of me. Gary and Hampton have been my point people, and they have always made sure that I understand exactly what my policies cover. We recently made a big move out of state and left the policies that we could with them in California because their care has been so thorough. I wish we could have taken them with us too. If you want caring, helpful, and kind expertise with your insurance needs… this is the agency for you."

"My husband and I have been with the Diane Sinner office for 12 years now and can’t recommend them enough. We have both our cars and our home insured and have always had peace of mind. Everyone is so kind and easy to get ahold of which really helps when you’re in a panicked situation. We’ve also chosen to stick with them after moving out of the city completely because everything has stayed just as convenient! Highly recommend!!"
