"Amazing team! I walked into the new office and the staff immediately helped me. I was able to file a claim for my accident within minutes and before I exited the building, a tow truck was already contacted to pick up my vehicle."

"I'm a long time customer and have been very happy with John Diehl and staff. They are friendly, professional and very helpful. Highly recommend this agency. (Reagan and Victoria are the best!!) Update- their prices have skyrocketed and continue to increase quarterly. (Not the agents fault), however State Farm itself is no longer what it used to be as far as pricing and reliability."

"I remember that Diana had helped me some time before. And she continues to be the very knowledgeable, professional, conscientious and friendly person that I remember. Today she helped me do something that I was dreading, getting my claim related receipts to my State Farm Adjuster in a timely manner. I was very concerned about this because as an Altadena fire evacuee all my computer gear was packed away. So I was very relieved at how quickly and easily Diana simplified this whole process for me. I gave a sigh of relief knowing that once again I was in good hands with Diana. and with “State Farm!”! A big thank you to Diana! George Hopkins"
"George - Thanks for taking time to write a nice review. Diana was so happy to read the kind words you wrote about your experience. We're focused on helping all our clients affected by the Eaton Fire. So glad we could be here for you. Thanks. John"
