About Us

Theiss Logo

Theiss Insurance Agency is an independent insurance agency and has been serving Harris and surrounding counties since 1984.  Formerly known as Walsh Insurance, we are located in Spring, TX just north of Houston and pride ourselves on over 25 years of excellent customer service with personal attention to every existing and potential client.  When you call our office, you will speak to a person, not an automated system or voicemail!

The mission of our agency is to provide the insurance protection our clients need by offering quality products, excellent service, and guaranteed value. We are committed to finding the best insurance solutions for you, your family, and your business. In a world where customer service seems to be dwindling away,  Theiss Insurance Agency vows to keep the traditional way of doing business a primary focus.  We believe we can grow with the evolving world of business and insurance while still providing the utmost personal care and attention to the people who matter most: our customers.

As an independent agency, we represent multiple insurance companies. We are able to compare coverage and prices in order to offer you the greatest value for your needs. In addition, we combine years of experience with cutting edge products to provide exceptional service to all of our policyholders.

We value the opportunity to discuss all of your insurance needs with you. Call us today and allow us to demonstrate our dedication to prompt, friendly service and superior customer care.
