Nasha Holt, MD has been in private practice since 1987. Dr. Holt received her medical degree from McMaster University Medical School in Ontario, Canada. She practiced Family Medicine until 2006, when she focused her practice exclusively on the care of patients with headaches and neck-generated head and face problems. She pursued extensive training in the Strategic Orthopedics Spine System, which provides a specialized physical therapy approach to neck-generated head and face pain. She believes that a holistic approach gives patients the best chance of recovery from chronic pain conditions which have often impacted many areas of their lives. Most of the patients she sees have been in chronic pain for years, and their lives have become very disrupted by the time they see her. Many of them suffer from depression and anxiety.

Dr. Holt gets to the root cause of head and face pain through a detailed mechanical evaluation of the patient's cervical spine. This forms the basis for instructing patients in progressive, therapeutic neck exercises that heal common sources of head and face pain. At the same time, Dr. Holt systematically addresses health-promoting changes in the areas of sleep, exercise, diet, nutritional supplements and stress management strategies. Her patients have huge needs in these areas.

Dr. Holt, her children and her extended family have lived in San Antonio since 1997.

Allison George attended Texas A & M University Corpus Christi for 3 years, majoring in Early Childhood Education. Her background in education helped her develop tools for effectively engaging with patients and for coaching them through our comprehensive wellness program. She started her career at the Headache Institute of Texas in 2013. Seeing our patients recover from chronic head and face pain as they work their way through our program inspired her passion for building our headache practice. This, in turn, has allowed her to climb the ranks from a part-time front desk employee to office manager. Over her tenure, Allison has become an integral part of the practice, facilitating growth of the Headache Institute of Texas, and allowing more headache sufferers to find relief.
