Who We Are

The Hisel Law Firm PLLC is a boutique firm concentrating in business and employment litigation, advice and counsel. The firm was founded in March 2008 by its founding partner, Mary Ann Hisel, with the goal of providing clients the highest caliber of legal representation with the flexibility, efficiency, economy, and personalized service that only a niche firm devoted to its clients can provide.

The firm's strength is in its foundation, which combines Ms. Hisel's seven years of actual, real-world experience as a Human Resources professional (in the University of Texas System and a subsidiary of Halliburton) with the elite training and skills honed during seven years of practice in the Labor and Employment section of Bracewell & Giuliani LLP.

The Hisel Law Firm brings this experience to bear for every client and tenaciously guides employers and business owners in maintaining workplace productivity, avoiding litigation, and engaging in preventative and best practices strategies to enhance the bottom line.

Our Clients - Our Partners

The best part of serving as a lawyer is the opportunity it brings to develop, nurture and maintain lifelong relationships with our clients, whom we see as our partners.

We believe this is what sets us apart: your ultimate success is our constant and all-consuming objective.

Our clients include municipalities, public school districts, public and private Universities, and companies ranging in size from Fortune 500 companies to small locally owned and operated businesses. We represent employers in South Texas and across the State in a wide spectrum of industries, with a focus on helping start-up and emerging companies grow into the powerhouses of the future.
