"John Diehl's office serves their Altadena customers very well, even in the midst of their own fire disaster. The staff has been very attentive and responsive to all of my inquiries and have assisted me on multiple homeowners as well as auto claims, renewals, and new policies. I would not be able to navigate these processes without their unending support. I am extremely grateful to have John Diehl as my agent. I look forward to many years doing all of my insurance business with State Farm. Thank you all!"

"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. (Diana is 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."
