Do you have any hesitation referring to a cardiologist, pulmonologist, or other internal medicine subspecialty?

"I certainly plan to practice along the lines of gastroenterology, cardiology, and other subspecialties, when I can; but I make liberal use of consultation for the best health impact on my patients. If someone does something better or is more qualified from a regulatory standpoint, I will willingly defer to, or partner with, him or her in the case at hand."
