Austin Holmes


Born and raised in the heart of Dallas, Texas, I have been steeped in the world of law from the very beginning. Growing up, my father, a distinguished attorney with an impressive 38-year career, was not only my role model but also the driving force behind my genuine desire to make a difference in the lives of others through the practice of law. In addition, his unwavering dedication to his clients was a beacon of inspiration that guided me to follow in his footsteps.

My journey toward becoming a lawyer began at the University of Texas at Dallas, where I earned a Bachelor of Science in Business Administration. I continued to pursue my passion for law at the University of North Texas at Dallas College of Law, graduating Magna Cum Laude with my Juris Doctorate in 2022. This accomplishment was not just a proud moment for me but also the realization of a lifelong dream that had been ignited when I first understood the power and impact an attorney can have on the lives of their clients.

Before attending law school, I had the incredible opportunity to work as a law clerk at my father's renowned firm, Holmes Diggs. This experience not only provided me with a solid foundation in the legal profession but also reinforced my core belief in the paramount importance of always putting clients first.

As your family law attorney, my passion for the law translates into a deep commitment to helping you navigate the complexities of your case while always prioritizing your best interests. I understand that each client's situation is unique, so I approach every case with empathy, determination, and a personalized strategy tailored to your specific needs.
