We are very happy with McNamara & Thiel handling our insurance needs. They covered my motorcycle the same day I requested insurance, and even late in the day! They just handled our insurance claim for hail damage. Very rapid response, and job well done, and provided a rental car to us very efficiently. Very happy!

Mitch Swanson

Very personalized service. We felt like our agent tried hard to understand our insurance needs and worked hard to offer us an insurance policy that was comprehensive and at the same time, a good value. Also, great communication skills on the part of everyone in the office. We really appreciate the efforts everyone makes to return our calls and explain the details of our insurance policies. :-)

In an increasingly complicated era of insurance advice and products, your financial future does depend on the advice you receive today. If you value personal customer service and independent advice, please contact McNamara & Thiel Insurance today.

Our family switched over to McNamara & Thiel a number of years ago. We could not be more pleased. Their staff is exceptional to work with and their response time is of the best in the industry. McNamara & Thiel manages all of my policies and check them at renewal to ensure that I am appropriately covered at the most affordable rate. They advocate for you as a client and they treat your policies as if they were for their own family. I regularly recommend them to friends and colleagues. Call them to set up a consultation today!

I have been a client since I lived in Fond du Lac over 20 years ago and have always been extremely satisfied and impressed by the customer service I have consistently experienced over the last 20 years. It’s so wonderful to call your office and be able to give my information to your receptionist who can literally assist me in 90% of the questions I have without having to ‘take a message and have someone call me back.’ The manner in which you guys train and manage your inner-office workflow—utilizing everyone’s skills—in your office is amazing and should be replicated by other insurance brokers…thank you! I highly recommend Steve and all the folks at McNamara & Thiel Insurance.

When it came retirement time and were confused by all the options. We met with Steve Sommerfeldt at McNamara and Thiel and he took the time to explain the difference in plans and helped make our decision easier. Since then whenever we have a question on a change one phone call and we are guided in the right direction. Highly recommend!

Patrick McNamara and the team are incredible! Everything is checked, rechecked, and confirmed before you see it. Simply hands down the BEST experience I have ever had with an insurance agent or agency. I refer friends as well as casual contacts their way and know that they will be taken care of. My grandfather worked with Pat and enjoyed the experience—which says a lot to the integrity and quality of service that he provides.
