Smith Allen Insurance agency was established in 1952 by Preston Smith and Albert Allen, former agents representing Millers Group in Fort Worth. Preston’s son, Larry Smith, joined Smith Allen in the 1960’s. He led the agency for four decades amidst several market cycles and the ongoing transformation of the personal insurance landscape in the Dallas area. Preston's grandson, Stan Smith, joined Smith Allen in early 2003, becoming the third generation of the Smith family to lead the agency.

Since Smith Allen first opened they have been writing insurance in the Park Cities, SMU, Highland Park, Lake Highlands, M-streets, Lakewood and Uptown areas of central Dallas. Over recent years they have expanded into North Dallas, Plano, Richardson, Frisco, Allen, McKinney and many other surrounding areas.

This agency has witnessed these communities evolve into what they are today, which has allowed the agency to gain a deep understanding for the neighborhoods, businesses, and people in the area. Today, Smith Allen is committed to providing solutions for people who have complex personal insurance needs.
