— Trey Hendershot

As a business owner or partner, you have worked tirelessly to build a livelihood that you are passionate about and proud of. The assistance of an experienced attorney can help ensure that your business has the right guidance to protect your assets through any business dispute or transaction. As the managing shareholder of Hendershot Cowart P.C., I look out for the best interest of our clients by utilizing our many years of combined experience practicing business law, business litigation, health law, and regulatory compliance.

Our tagline is: "Your Attorney. Your Team. Your Law Firm for Life." And that's true. It's my approach to client service, and it lays the foundation for our collaboration – now and into the future.

Our Business Law Team Is Dedicated to Your Success
This dedication means we are actively involved with you, your business interests, and your legal challenges. Simply put, I am genuinely invested in building your venture, or in resolving your legal challenge, as is every attorney who works here. We are aggressive in pursuing your goals. We work to exceed your expectations using our experience, knowledge, and expertise.

My Goals Are Based on Your Goals
My decision to practice law was inspired by the strong work ethic of my father and grandfather. Being a successful attorney requires dedication and experience. Whether reviewing an employment contract or providing representation in complex business litigation or a governmental regulatory investigation, I am continuously seeking the best possible outcome for you and your business.

I have extensive experience representing businesses from startup to full operation, from helping file initial incorporation to managing multimillion-dollar transactions and litigation. I have counseled thousands of clients through litigation, arbitration, mergers and acquisitions, and with OSHA citation defense, Texas Medical Board and other licensing investigations, Anti-Kickback Statute and OIG investigations, fraud and abuse investigations, and STARK Law compliance.

Many of the clients I have represented for decades continue to flourish with my firm’s ongoing counsel. And when the inevitable litigation comes along, I've helped these same clients enforce their rights, defend against suits, and prevent future problems with sound regulatory and legal guidance.

Clients Receive the Attention of All Attorneys
Every week, each practice section collaborates as a team to discuss the various aspects of your case. Every attorney participates and is encouraged to provide input, even if that attorney is not actively working on your case. This approach allows us to create unique solutions for the success of your venture or the resolution of your legal challenge. My entire law firm's resources, expertise, and experience are applied to your matter.

My Faith Is the Ethical Foundation for My Law Firm
I am not shy about my faith. I am a Christian and have played an active role in the church for most of my life. Faith plays a major role in my approach to client service and case preparation. We don't cut corners. We are adamant about doing the best job that we can for you. And when the work is done, I personally review our clients' monthly bills and efforts recorded to be sure that you received the benefit for which you were billed. Not every law firm can make this claim.

Working Toward Your Continued Success
My mission is to continue to gain the trust and confidence of the business owners, executives, and entrepreneurs I have the privilege of representing. Let me help take your business or health care practice to the next level, as I have done for so many friends and clients over my more than three decades as a business lawyer. I will zealously represent your matter with my personal attention, experience, and unparalleled preparation.

Great Attorney who Genuinely Cares About his Clients
I was referred to this attorney from a friend of mine for my divorce case. He genuinely cared about my situation and walked me through each step of the process, and he did not seem primarily concerned with his own time. I felt relieved with the stress of my divorce knowing he was on my side, and he gave me great advice to use down the road. I highly recommend Trey Hendershot.

Great customer centric law firm.
I've been acquainted with Trey for over three years. Not only have I referred friends to his firm, I am working with him on a business start up. Trey has been extremely helpful with educating me on the hurdles and obstacles that go along with starting up a new business. I work in the legal industry so I know how intimidating attorneys can be but my experience with Trey has been relaxed and informative. Without a doubt I would refer Trey and his firm for any business and family issue.

Failed to maintain my corporate filings.
This attorney filed my corporate report for my corporation. One year I noticed that a corporate report had not been filed. I actually wrote to the attorney inquiring why the corporate report had not been filed; no response. Subsequently got notice from state that my corporation had been dissolved because no corporate report had been filed. Had to hire another attorney to get my corporation reinstated.
