Since 1994, HealthTexas Medical Group of San Antonio has been one of the most prestigious primary care physician groups in the country. HealthTexas is nationally recognized for its Art & Quality of Medicine program as well as having its physicians listed by their peers as Best Doctors in America®.

The expertise of HealthTexas Medical Group caused a natural transition into clinical research. With the strength of a large, quality physician-owned and driven medical group, quality clinical research was inevitable.

HealthTexas Research Institute® was developed under the direction of Dr. Richard Reyna, Dr. Aris Nikas and Dr. Ramon Colen. Due to the efforts of these Board Certified Internal Medicine physicians, the HealthTexas Research Institute® has become one of the leading clinical research institutions in the country. Current principal investigators are Aris Nikas, MD and Michael Dominguez, MD, with Richard Vargas, PA-C as sub-investigator.

Each study provides a valuable piece of the puzzle to future cures and answers to the medical community. HealthTexas Research Institute® commits to continually strive to improve the lives of the community we serve through high-integrity, productive and cost-effective clinical research.
