2011 Created the program of “Surgery Without Medical Insurance” having identified the problems that the patient suffers without medical insurance in the complex bureaucratic system of health in the United States.

Dr. Enríquez finds that the only way to help the uninsured is to advocate directly for them, in all their health, economic and social needs; establishing a strategic alliance with the first hospital (San Joaquín Community Hospital), which opens its doors to this pilot program called “Surgery Without Medical Insurance”

Once the program and operating system of Surgery Without Medical Insurance has been established, a network of surgeons, specialists, laboratories, x-rays, etc. is formed, to be able to fulfill all the surgical needs of the patient without medical insurance, thus managing to reduce the costs considerably of the surgery, giving the opportunity to individuals without health insurance to access a health system without impacting the family economy and at the same time keeping the patient healthy, active and productive in their community.

Over time other hospitals took the example of helping their community and have joined the network of Surgery Without Medical Insurance; Mercy & Memorial Hospitals, Delano Regional Medical Center, Heart Hospital, PPSC and Bakersfield Specialist Surgery Center. All with the interest to promote health in their community.

To date, more than 5,500 patients have been treated, not only from California, but also from all parts of the United States. It should be noted that 84% of these patients without health insurance are of Mexican nationality.
