Welcome to our web site!

Shirley Colyer

Thanks for visiting.

This web site is designed to be a complete insurance resource for personal, commercial, and family insurance coverage in the state of Texas.


This site also includes links of interest to people moving to or even traveling in the Lone Star State.


The buttons at the top will link you to pages that will answer some of your questions, and we are always available by telephone or e-mail to offer you personal, one-on-one service.  We take pride in our superior customer service, and have built a reputation for client satisfaction and strong agency-client relationships.  As an independent agency, we can access many different insurance providers to seek out the best possible pricing for your insurance needs.  The agency can handle almost any property and casualty or life and health product available; if we are unable to meet a unique insurance need, we will refer you to someone who can.  We are truly your “one stop source” for any Texas insurance product or question.


Scroll down for more information on our products, services, and staff, or use the buttons to “surf” our other pages and links.  Thank you for visiting our site. Please bookmark it, and visit it often. We look forward to hearing from you.
