Dr. Cummings also had the opportunity for Chiropractic outreach by participating in a Clinic Abroad program in India. This was a turning point in his career. It was during this time that Dr. Cummings experienced the miracle of what an adjustment can provide to an individual. In this outreach Dr. Cummings saw amazing results for the Indian citizens he treated, most of which were too poor to afford medical care. It was a truly humbling experience for him.
