The Service Insurance Group Agency (SIG/Henderson), founded by Garry Antunes, Sr. and David Gray, began in 1997 as a small operation. The agency has grown to its current status as one of the largest locally owned agencies in East Texas. With a staff currently numbering over ten, SIG Henderson services clients not only in East Texas, but all across the state. As a result of its reputation for competitive pricing, fast claims service and knowledgeable staff, SIG Henderson has gained an array of clientele with diverse backgrounds and needs which has provided the opportunity to form alliances with numerous companies that have markets for almost any type of risk in Texas, as well as provide a wide variety of financial services.

What does that mean for you? The Service Insurance Group continues in its efforts to provide excellent coverage at a fair price to its customers in East Texas as well as throughout the state. The agency, being an independent agency working for you, not one particular insurance company, prides itself on being large enough to have access to almost any kind of product, yet small enough to be familiar with each of our customers. We not only specialize in P&C products, but life, health, annuity and other financial products as well.
