About Us

Pain & Stress Center Products
San Antonio, Texas

The Pain & Stress Management Center was founded in San Antonio in 1979. Our goal was to offer patients a total multidisciplinary approach, including natural alternatives to toxic drugs . We offer orthomolecular therapy, education and research information to the public and health care practitioners. Our professional staff of nutritional consultants can assist you with a complete nutritional program.

Dr. Billie Sahley, Ph.D., C.N.C.

In 1980, we began extensive research in neurotransmitters and brain chemistry. Our research led us to answers for mental stress, physical symptoms, and a deeper understanding of brain function. We developed a complete line of neurotransmitter support formulas to address mental as well as physical pain. Then, because anxiety and stress are such pervasive problems, we developed our Anxiety Control 24 formula, and we were awarded a patent for this formulation.

Katherine Birkner, C.R.N.A., Ph.D., C.N.C.

Over the past 30 years, we have observed remarkable results with, not only our patients, but also thousands of customers. Our research into brain biochemistry has opened up new treatments for anxiety, stress, depression, chronic pain, fibromyalgia and hyperactivity. The Pain & Stress Center product line addresses the multitude of problems facing the American public. We continue to promote education through research and publications, and to offer natural alternatives through product development. The focus of our work is providing natural answers and helping people discover how tremendously better they can feel by returning to the brain what naturally belongs there.
