Rene Sigman

Of Counsel Attorney

Rene Sigman is a devoted mother of three born and raised in Texas. She graduated from Texas A&M University and attended law school at South Texas College of Law in Houston, Texas. At South Texas, she joined the nationally recognized South Texas advocacy program and graduated from law school, receiving the Dean’s Most Outstanding Advocate Award.

Rene became the first attorney in her family and one of the first woman attorneys in Texas to practice First Party Insurance law on the policyholder/plaintiff side. Over her career, she has represented all types of policyholders, including school districts, municipalities, and residential and commercial businesses, on their insurance claims. Additionally, Ms. Sigman is one of the first & few attorneys that has ever tried a first-party hurricane lawsuit in Texas.

She has spent most of her legal carrier representing policyholders who have been underpaid or denied by their insurance carriers on their insurance claims. Her peers revere her as one of the pioneers in first-party practice in Texas.

She is recognized as one of the best policyholder insurance lawyers in Texas and beyond. She has been consecutively named to the Texas Super Lawyer’s lists since 2011, an achievement gained through her dedication to her clients. She was also named to the Top Woman Attorneys list in Texas in 2019. In addition, she is recognized by her peers for outstanding results in consumer protection and insurance.

In addition to the law, Rene’s other passion is working with Texas Children’s Hospital and NMDP/Be The Match to make a difference in pediatric cancers and bone marrow transplants. Rene’s son, Blake Chandler, is a cancer survivor and a bone marrow recipient. In 2015, Blake was diagnosed with ALCL (Anaplastic Large Cell Lymphoma) at nine years old and received six rounds of traditional chemotherapy to save his life. Unfortunately, after completing all six rounds of chemotherapy and being declared “cancer-free,” Blake relapsed in early March 2016 back to stage 4 ALCL.

There was a perfect match across the world for Rene’s son. Blake found his match in Isreal through the Be The March registry and had a bone marrow transplant in August 2016 at Texas Children’s Hospital. Today, her son is alive and well.

Her journey with her son through cancer and transplant shaped her desire to help others in similar situations. Since then, she has made it her mission to help others who find themselves on similar journeys with cancer and transplant. In addition, she is an advocate for access to life-saving drugs and procedures so that all pediatric cancer patients can have a chance at a life free of cancer.

Your legacy is every life you touch. I live that motto daily, from helping those that have been wronged by their insurance companies get justice inside and outside of the courtroom to those that battle for access to life-saving drugs and procedures. My greatest joy comes from ensuring people overcome obstacles and get the help they need.

Areas of Practice

Ms. Sigman is considered a pioneer in first-party practice on the policyholder side. She has handled cases against insurance carriers over the last 20 years. Her knowledge and understanding of the Texas Insurance Code and laws about insurance disputes have been instrumental in prevailing as the policyholder’s advocate.
