Dr. Alex Cox and Dr. Doug Cox joined Dr. Gonstead as staff doctors in 1964 and 1967 respectively. The Cox brothers trained and worked alongside Dr. Gonstead for the rest of his practicing life. Dr. Gonstead was so pleased with the respect, dedication and coherence of the Cox brothers to his teachings and technique, that in 1974, he transferred and sold the Gonstead Seminar of Chiropractic to the Cox brothers.

This "passing" of the Gonstead knowledge, not only included the teaching of his work through the Gonstead Seminar, but his faith and confidence in Dr. Alex and Dr. Doug also included the transfer and sale of the Gonstead Clinic and motel to the Cox brothers.

Knowing that his teachings and legacy would live on under the guidance of Drs. Alex and Doug, his lifetime of work was safe from being altered or changed. Dr. Gonstead's dedication and service to the patient, above all else, had been absorbed and passed on to the Cox brothers, and is still being practiced and taught by these two masters of the Gonstead system today, along with their current staff of fellow instructors.
