★★★★★ 5.0 Jacqueline DAVIS Cobin · Feb 2026

I have been a State Farm customer for a few years now and have always had a good experience. Diana and her team are very professional, kind, and helpful. Thanks, Kay Kirchner for the very helpful tip on life insurance and solving my automatic payment issue!

★★★★★ 5.0 Bob Roska · Dec 2025

We have been satisfied State Farm customers for many years, working with Diana Kostel and her staff for most of that time. Recently they came through for us again. During Thanksgiving week, we decided to purchase a new RV. Despite the holiday week scheduling, Kay, Sue and Diana received my emails and phone messages and arranged for insurance coverage by the time of our closing. As always, the State Farm Diana Kostel agency provided us great service.

★★★★★ 5.0 Myles Hopper · May 2025

We are new customers of this remarkable agency, and had an auto insurance claim within a few weeks. The staff in the claims department were polite, considerate, and prompt in all communications by phone, text, and email. Compared to other agencies we have worked with over the years, Diana Kostal Agency is right at the top. Additionally, we were guided by the office manager, Kay, during our initial meetings to determine the coverages we need, and then through the claims process. She is someone we trusted immediately. We recommend this agency without reservation.

The Diana Kostal Agency is knowledgeable, friendly and has always taken the time to care. They are responsive and took the the time explain the policy options and details. It is no wonder that I have worked with the agency for over 20 years. I highly recommend new and experienced insurers work with this agency.
