"Ken is super helpful and always kind. Our starter went out on our vehicle yesterday at the gas station. I called State Farm and spoke with Dennis Sullivan team and (our agent, Ken). He gave us their tow truck assistance number, and we had our car towed in no time back to our house, where my husband was able to put in a new starter. Not only do we have full coverage on our vehicle, but it's actually a really good price, and Ken, Dennis, and everyone else that works there are so pleasant every time we've ever had to call them. Super grateful that this is who I have my car insurance through, and also the brick-and-mortar policy for our small business. 10 out of 10, definitely recommend!"
"Thank you, Lorie! I'm really happy to hear that Ken and our team were able to assist you quickly when your vehicle's starter went out. It's great to know that you're satisfied with both the coverage and the service we provide. We truly appreciate your recommendation and your trust in us for both your car and business insurance. Let us know if we can help with anything else!"

"Owner would not bind auto coverage until we came into office. After moving from Ohio, owner told us we didn't have to come in and shared he & his agent did not complete the replacement cost estimate on our home for a closing resulting in incorrect premium & escrow shortage.
Research the Palisades and Marshall Fire impact to SF customers and ultimately led to the companies financial rating downgrade."
"Hi Justin, it’s been a couple years but I understand your frustration from 2024. As mentioned in Brooke’s review, I hope the Agent you have been working with for the last 2 years has met your customer service expectations."
Brooke Thomas

"Completely mismanaged our homeowners premium 3 weeks before closing on our new home. Would never do business with this agent/agency again."
"Hi Brooke, I hope you and Justin are doing well and that the transition to Colorado has been a positive experience for you. I remember the frustrating experience you had with us in 2024, and I sincerely apologize once again for that. I truly hope that the customer service with the agent you selected two years ago has met your expectations. Take care."
