Because of his philosophy, Dr. Contreras taught his medical staff to never prescribe treatments that would destroy the quality of life of the patient. He also insisted that Oasis of Hope physicians offer therapies that they would be willing to take if in the same circumstances. His emphasis on the doctor-patient relationship, along with his integration of natural and conventional therapies with emotional and spiritual counseling, were the principle reasons why more than 100,000 patients from 55 nations have come to Oasis of Hope for treatment over the last 45 years.
