About Us

South Texas Insurance Agency, is a local insurance agency in Laredo, Texas.

The owner has been in the insurance industry since 1997. After 9 years of hard work and dedication to this field & the support of her loving husband, she found the opportunity and established her own business. In 2006, the 1st location on 4815 San Bernardo Ave (78041) was established. It was more than a dream come true, satisfaction came to play as she has always loved helping out people and what more than your own customers?

A year later, a 2nd office was established which is located at 2201 San Salvador St (78046).

By that time, the offices kept growing and the vision of the owner was to continue to help customers around the area & out of the area since it was most requested. That’s when in September 2012 we had the privilege to expand to San Antonio, Texas located at 3307 S. Zarzamora St (78225). Glory be to God that He has blessed this business for so many years & we look forward to continuing to grow in this community to offer great rates in auto, motorcycle, home, commercial, workers compensation & much more.

In October 2018, a 4th office was opened in Laredo, Texas in 1602 Corpus Christi St #5 (78043) and we are looking forward to a great start, as for the best is yet to come.

Our business has great employees that are ready to serve our clients every day.

We are open Monday-Friday from 9 am to 6:30 pm & Saturdays from 9 am to 4 pm.

If assistance is needed before or after hours of operation, we will gladly assist you. You can reach us easily by email: or Facebook messenger.
