John is a great, responsive, insurance agent. I needed a new business insurance policy and decided to try John Diehl for a quote. Not only did I get a quote that met my budget, but John also gave me great options for payment to meet my business needs. He responded very quickly, and got my policy written up as soon as I gave him the necessary information. I wouldn't hesitate to recommend John for another policy, either to myself, my business, or for a friend or family member. I give him 2 thumbs up! read more

I heard the state farm office on Mariposa in Altadena near Lake ave. was destroyed in the eaton fires; I am sorry to hear that; I visited the STate Farm office but the agent and staff did not seem too friendly; the prices that they quoted to me were excessive and far too high. State Farm is not the same company that it used to be 25 or 40 years ago. read more

Another great State Farm experience just 3 days after Christmas 2024...my spouse's car was parked in front of our home & was hit by a car & totaled (the driver was not seriously hurt thankfully)...our car was towed away & we rented a car for a few weeks while we looked for a new/used car. John's team reviewed our towing receipt & car rental receipt & we were reimbursed promptly while our totaled lease car was paid off allowing us to find another vehicle. This was mostly processed during the time of the Eaton inferno fire. Thank you John & your team for prompt service! read more

I had an unfortunate experience with Mirna while trying to understand some changes that had occurred on my statements. She made some accusations that were out of line in a rather nasty tone which was simply unacceptable. I asked to speak with John and she said I would only be directed back to her. I transferred all three policies to another Sate Farm agent. read more

Been using this office for a few years now, and Virginia is still the absolute best! She's quick, kind and feels like family! My family will be her client forever! read more

Awesome office. Very welcoming. I needed a life insurance policy and after quoting around, I found that State Farm has some of the best plans and affordable policies. I didn't even make an appointment. I walked in and was greeted by the pretty ladies in the front and was insured that same day. read more

John has been my Insurance Agent for 10+ years for multiple insurance policies including: home, auto, and renters insurance. I just recently added two auto loans with John because the rates were so unbeatable! I recently moved from Southern CA to Northern CA and he drove all the way up here to sign auto loan documents and go over future life insurance policies with my husband and I. John and his team are beyond amazing! The ladies in the office are so sweet and always willing to help. Ron was wonderful to work with as well, very informative and passionate! I would never think to go anywhere else! Thank you John for your constant dedication and for always having my best interest at heart! read more

Virginia is extremely helpful when it comes to all my questions. She is the reason I have stayed with State Farm for so long. She found me the lowest price she could for my insurance and explained all the options I had thoroughly. read more

After reviewing the list of agents on the State Farm website, I reached out the John Diehl's office. One of his team members helped me very quickly with home insurance that was a perfect fit for my needs. I was interested in switching car insurance and happily was able to get a cheaper rate without loss of coverage. I would strongly recommend this office for their customer service, responsiveness, and personal attention. Super shout out to Mirna! Thank you for everything and I look forward to a continued partnership. read more

John is my insurance expert. He answered all my questions about insuring my wife's engagement and wedding rings, recommending the best policy for our situation, giving us peace of mind. Thanks John! read more

I love this place! I'm so glad to had switched from Infinity to State Farm. Mirna, was and is my agent. She has helped me with great deals for my car insurance. Always very courteous, professional and attentive. Always willing to go out of her way to help me with anything I need. I reported an incident, and they are amazing in helping you. There's no delays for a car rental, and for State Farm to inspect your car. The process is done sooner then you think without any hassle. I definitely recommend this office. read more

I was searching around for insurance and getting quotes from places and this office was really helpful and Stephanie helped me understand how insurance works and gave me that piece of mind. I was feeling a bit overwhelmed so I really appreciate the excellent service! Thank you- everyone there was cordial and very welcoming- more insurance places need to be like this office! read more

I love working with Virginia! She has helped save me a lot of money over the years. Every time I have a question, she's always so quick to respond. Before State Farm I was bouncing around from insurance company to insurance company but now that Virginia is my Agent, I'm a customer for life! She's the best! Ask for Virginia read more

I am a college student. My insurance goes up every month and i am only notified when the bill is due. Smh. Hopefully things change soon.

The best insurance agent. They help me with all my problems and issues especially dealing with big State Farm. I appreciate the two girls in the office. They handle their business without a doubt. Thank you. Jay read more

Where do I start???! John Diehl and his staff are highly professional and knowledgeable. Anytime I have a question regarding my policy, I know can count on them to answer my questions. Mirna, Virginia and Stephanie have great customer service and I appreciate the time they take in order to help me. If your looking for a great State Farm agency, you must visit this office!! read more

So before I write this review let me start off with I've been with many insurance companies since I began to drive with that being said the competition does not match to the superb experience I had with this state farm agency... so let me begin earlier this week i called my state farm agent Mirna and she greeted me as if we have known each other for years and also blessed me with dropping my monthly rate. I am so happy to have come across her as an agent I would highly recommend her she truly does put the customer first. I am also very happy with my experience as a state farm customer they always help me with any issues I have..... believe me I have issues. Lol. .....Keep up the good work guys!!!! :) read more

John and his staff at State Farm have always helped my family find the best coverage and rates. Whether it was my son's good student discount or a multi policy discount- John Diehl is always there to let me know about the most current benefits. read more

John and his staff are always helpful to us (family & business) In this era of web base insurance companies it is alway nice to be able to call and talk to a human. And to top it off their rates are great!!! thanks John Russell Hollinhurst Hollinhurst Printing, LLC read more

Ask for Virginia, she is the best! I been with state farm for a little over a year and Virginia has helped since the beginning! She's extreme helpful and will go out of her way to help you out. If you want professionalism and honesty talk to her. read more

If I could zero stars I would! Steer clear of this office. These are the most incompetent group of people I have come across and has horrible customer service. I have been with Statefarm for many years and the agent I had before (who was absolutely amazing) moved pretty far so I decided to give John's office a try. Big mistake on my part! Premiums were always going up, but they were always trying to sell another policy to give a "discount", when billing questions arose nobody ever knew anything, and to get direct answers I had to call Statefarm customer support myself. Needless to say, I'm done with this office and the incompetent agents associated with it! read more

Absolutely amazing insurance agent -- extremely responsive and helpful. We've been customers for years and highly recommend him.

I switched from Allstate to State Farm with John Diehl because he was able to bump up my coverages and add a $1mil umbrella policy for almost the same price as I was already paying. read more

I wasn't sure I needed a new insurance agent. Until I decided to have John Diehl look at my policies for a free review. John ended up saving me a lot of money when I brought my two vehicles to State Farm. Then I referred my father-in-law and he brought multiple policies. read more

John is knowledgable, patient and personable. I have worked with a couple of his clients; and they are very content with his services and spoke highly of him & his services. He has also been very kind to my own clients. Whenever I have questions about property and casualty insurance, John is the one I always go to. I highly recommend him. read more

Very poor experience. I had to call so many times to fix their frequent mistakes on my multiple policies. Often, they did not get back to me on my queries and I had to call back more than once to follow-up on issues. read more
