There is a traditional antagonism between MDs and other credentialed practitioners, such as chiropractors, holistic physicians, acupuncturists, practitioners of hypnosis, and even DOs. At the hospital or large group level, it is no longer a philosophical issue, however, but purely financial. As these specialists gain credibility and acceptance in the health care marketplace, you have to present yourself as being open-minded, because as the American Board of Medical Specialties expands (or at least the authorization by state medical boards), these providers will no doubt end up beside you treating patients.
