A Family Firm Steeped in History At the Griffith Law Firm, family means everything. As you and your loved ones age, we will be your personal advocates, guiding you through every legal concern. Our success comes from our unique grandfather-granddaughter teamwork, which combines years of experience, compassion and knowledge of the law. We bring a strong Texas work ethic for a focused approach on senior needs and estate planning for all ages. Founded in 1957, the Griffith Law Firm has earned a reputation as a highly respected and effective community oriented firm in Dallas and Henderson County and neighboring communities . Our family began farming in Duncanville when there were only 200 people, and now the population is nearly 40,000. In 1960, Mr. Griffith constructed the building in downtown Duncanville on Main Street, which is still a staple in Duncanville's historic downtown district, and shortly thereafter became Duncanville's first City Judge.
