In the 3 years we have been working closely with Leanna, she has been nothing short of incredible! Our home owners insurance was coming to an end with a provider and she was quick to provide us with the next best option. We don’t know what … More we’d do without her assistance, knowledge and experience within the insurance industry, as she continues to make each process effortless and easy on our end! Certainly recommend her if you are looking for help on your insurance coverage options and process! -
We have been with RL Thomas for over 5 years. They are always very responsive to our questions and the staff is very professional and nice

We are new transplants to Missouri and purchased a home. The service we received from Lauren and RT Thomas Insurance LLC in assisting us in obtaining the insurance for our home was outstanding! Lauren and her team were thorough, efficient, … More supportive, and friendly! We recommend this company to anyone without reservation! Thank you for making our experience of obtaining insurance a positive one!Richard and Rebecca Hoffpauir

We’ve been very pleased with our experience with Lauren Castillo and R.T. Thomas Insurance Agency. Most recently, Lauren helped us review our insurance and make the switch from Liberty Mutual/Safeco to Travelers.Lauren did a great job walking … More us through our options, answering our questions, and making sure we understood the coverage rather than simply focusing on price. She also noticed that a previous roof repair had never been properly followed up on with Liberty/Safeco to reduce our annual premium. Thanks to Lauren bringing it to our attention, we were able to go back to them and receive a reimbursement for premiums we had overpaid. We never would have known to pursue that without her help.The entire transition to Travelers was handled smoothly, and Lauren was always responsive and easy to work with. It’s nice having a local insurance agency and someone we know we can contact directly when we have a question or need help.We’ve been very happy with Lauren and R.T. Thomas and wouldn’t hesitate to recommend them to friends and family.

I love RT Thomas! I swear they must be the best insurance agency in the world, and I never thought I would have such strong positive feeling about insurance of all things. My friends from outside MO are literally jealous that I get to work … More with them after I described some of my experiences.They’ve been not only great at shopping for exactly the coverage I want (for instance, for earthquakes), but Raina has also gone out of her way to help us during recent issues we had with insurance claims. Working with RT Thomas makes you feel like you have a partner when it comes to insurance. It’s not just a service. It’s a real professional relationship.So if you’re searching for an insurance agent, your search has concluded here. Congratulations on finding the best option that’s out there!
