About Our Firm


Who We Are

Caring. Thorough. Sincere. Skilled. Calvert & Associates seeks to provide these things in their representation of clients seeking justice. Established in 1996 in Houston, the firm has several areas of practice. A primary focus has always been health care liability issues and defending health care providers. The firm represents and serves clients throughout Texas.  

T. Marc Calvert founded the firm and he has been board certified by the Texas Board of Legal Specialization in the field of Personal Injury Trial Law since 1994. Early on, he earned, and has maintained, an AV rating—the highest an attorney can receive—by Martindale Hubble. Since 1986, Mr. Calvert’s litigation experience and advocacy is enhanced by his genuine dedication to those he helps in the legal arena. There is an emphasis on personalized attention to every single client, and developing a litigation plan that is customized to achieve the best result. Mr. Calvert and his associates are dedicated to being zealous advocates and will approach every matter with both tenacity and finesse.

What We Do

We help people. Whether it is defending a doctor, pursuing justice for someone who has been wronged or hurt, or crafting a contract or letter, there is a commitment to excellence in our daily work. We have solved complicated matters with a phone call or letter; and, we have also fought for many years on cases requiring trials and appeals. We will do what it takes to provide elite representation to those who entrust us with their case.

A prime work of Calvert and Associates is to represent healthcare professionals in a wide variety of fields throughout Texas. Experienced from beginning to end, from initial claim management through trial and appeal, Calvert and Associates attorneys are ready to help you and to take care of your case. 

Calvert and Associates also offers expertise in healthcare licensing and regulatory matters, business formation, employment law, administrative and regulatory matters, discipline/grievance proceedings, premises and products liability, family law, mediation, and general estate planning, wills and trusts. 

Calvert & Associates is committed to delivering the best possible results for your case and one that is targeted for your unique situation, whether via motion practice, alternative dispute resolution, trial, or appeal. No matter which avenue is taken, the professionals at Calvert & Associates are experienced and prepared to take your case in the direction that serves your best interest. 


Our Philosophy

We fight for our clients and no one will work harder to achieve the best result possible. This approach is based on balance and preparation. Mr. Calvert is a family man and he has encouraged a firm philosophy that a well-balanced life leads to better work being done and better case results. That this firm culture works is proven by the fact that many of the firm’s employees have not worked anywhere else. For example, Mr. Calvert’s paralegal, Carol Storm, has worked with Mr. Calvert since he began practicing law in 1987 and she has been the office manager of this firm since its inception in 1996. Most of the attorneys are hired as law clerks while in law school and have stayed on as associates. Calvert and Associates is proud of its consistency, reliability, and stability evidenced by its dedicated and loyal employees. This positive tradition easily translates into a momentum which allows the firm to provide attentive and consistent care to its clients. Our attorneys are also active in their local communities and churches, participating in service projects and volunteer work.  


Further Expertise

Calvert and Associates attorneys have a wide variety of educational backgrounds and interests, all of which provide unique skills and insights into your case. Our attorneys are also leaders in our field, self-publishing our widely sought after Quick Reference Guide for Health Care Liability Issues and producing the DVD series of “What Would a Jury Do?”. If you get the chance, listen to our CDs on the Texas Medical Board and on Basic Anatomy of a Lawsuit. These provide the inside tips and principles from a long career in this area of the law.  

The firm also provides continuing education to insurance professionals and healthcare practitioners. Mr. Calvert has appeared on the popular podcasts EMRAP and Risk Management Monthly. He has also given several presentations at a variety of medical schools and residency programs.
