Richard Morales, DC

Dr. Morales received his training at Logan University in Chesterfield, MO, where he and his classmates were inspired to continue learning long after graduation for the benefit of their patients. After receiving his doctorate, Dr. Morales continued to study under many doctors from the midwest to the west coast, in addition to countless seminars. While Dr. Morales enjoyed his time in research and found the work rewarding, he wanted to do more to directly impact the lives of others. He feels there is no greater good than helping those in his community find a path towards health. Having been exposed to the incredible innate intelligence within ourselves, he chose to pursue a path that would allow him to collaboratively support patients through natural healing.

In 2015, he moved to Texas to be close to family and support his classmate Dr. Sammy Tao in creating a practice with a more integrated patient care approach. In 2017, with the opening of Texas Regional Health & Wellness, Dr. Morales hopes to expand his impact on his community by continuing to engage and educate patients on health and wellness.
