"Super awesome team, from the minute that I took the phone call from gus I knew that I had the right team in my corner, he walked me through every policy that my budget would cover, what it did/didn’t cover and help me pick the right one that I needed, and even show me ways to save money that I didn’t know about. Super helpful to have someone local should I need it. Thanks guy’s!! looking forward to keeping them for years to come."

"Enjoyed my experience engaging with Gus and Justin at Justin Costello State Farm Insurance. Everyone is very personable and friendly as I searched for a local Ins. Co. to address my Auto Home and Rental insurance needs under one location. Found them to be competitive and comprehensive in their offering. Needed my first towing experience with them the other day and the call into the office was received by a real person who quickly gave me options to improve tow truck response time coordinated billing so all went very smoothly. Highly recommend!!!"

"Gus Murphy came through for me when it looked like I was going to have to insure my home with the Fair Plan. He’s responsive, quick, and willing to go above and beyond to handle business. This office is highly recommended."

"I got a car not long ago and I couldn’t get a proper quote online and active my insurance immediately. Lexi who located in this office helped me a lot getting my auto insurance done. She explained every nitty gritty of the insurance police and the experience was great. She sent me a thank you card later on which I think is very sweet! She also called to follow up with me to make sure everything is going smoothly. I’d say it’s a 10/10 service."

"Justin and his staff have been great, especially Teammmber Lexi Cameron. They have helped tremendously in my move from out of state back to California. They transferred all of my policies and communicated with my former agent to make the transition as easy as possible. I highly recommend them for any of your insurance needs."

"I wanted a quote to compare my current car insurance with another provider. Gus quickly contacted me and directed me to the steps. After a few minutes, I was on my way to saving a nice amount per month for the same coverage. I appreciate the friendly and timely service from Justin Costello - State Farm Insurance."

"I was contacted by Justin while researching an alternative homeowners policy that I have held for 36 years, but received the dreaded non renewal notice due to “wildfire risk.” Justin was able to assist me in securing a new policy, and was able to assist me in reviewing all of my home, auto and umbrella needs. He has extensive industry experience, including corporate positions which results in a professional and thorough explanation that generated s high degree of confidence for me. Without reservation, I would recommend his agency for any related insurance needs."

"I’ve been with State Farm for years. Our business truck was smashed by a tree in a recent storm, and without it, our business comes to a complete halt. Lexi and Tess at Justin Costello State Farm have provided us with top notch customer service, and I am so thankful for them and that State Farm is our Insurance carrier. I definitely recommend them for quality customer service."

"Lexi is AMAZING there. She ran multiple quote types for me so that I could figure out what worked best for our home and auto. She took all phone calls, answered all questions and offered advice without ever getting frustrated. Justin was very helpful as well - he made sure the quotes were processed and answered any questions that we had. So glad that we did everything through their office!"

"Justin exemplifies why you should work with a professional as opposed to buying from an online company. Justin spent hours customizing our policies for my family and tailored it just for us. Not a cookie cutter approach. He also gives great advise as to what we needed and what we didn’t need and reminds us when there’s an opportunity to save. I never feel like I am being up sold on something I don’t need. Extremely responsive, professional, and easy to work with. True small business owner that cares about his customers."

"Crystal Cathay and the team at Justin Costello State Farm are absolutely amazing! I recently purchased a home and wanted to add home insurance to our current package and Crystal was so responsive and outlined several options for us. I had questions about earthquake insurance and just the home buying experience in general as she recently went through it and I felt like Crystal truly cared and took the time to offer advice on matters outside of her job title. She is the best!! I felt like she genuinely cared about our best interest which isn’t always the case with insurance providers. I give her and this specific team 5 stars! I always feel so taken care of whenever I need something. Best, Angela"

"What a great experience! I recently signed up for life insurance with Justin at State Farm. He really went the extra mile and made sure that I was aware of all of the details that need to be taken into consideration when selecting the right policy. I felt no pressure and I know that Justin had my best interests at heart as he guided me through the process. If you have any insurance questions then I would definitely recommend giving Justin a call. It is very rare that you find a professional that tells you what they “CAN” do for you as opposed to what they “CAN’T” do for you nowadays. 5 Stars"

"Best service!! My husband and I both work in the insurance industry so we were very careful about where we placed our homeowners coverage. Not only did Justin provide us with a policy with superior coverage but it was a better price than any other quote we had received."
