Care Philosophy

This content was provided by Dr. Demeo "Everybody that comes in the door has a different story. And so you start off trying to be a detective, and you pull in the information that you have. And then you have the ability at a place like Rush where you can then access other colleagues who have different experiences and different information. And you have all the medical journals in our library. And you piece it together, and you bring it back to your patient. And when it works, it's the greatest thing in the world. Celiac disease is an immune-mediated reaction to the proteins in all the grass grains - so wheat, barley, and rye - and that protein collectively is called gluten. The treatment for celiac disease for a long time, and still the mainstay of therapy, is the gluten-free diet, removing that from the diet. However other drugs are in the oft, waiting to be introduced. I think that over time we are going to learn more. And trying to unravel those things and to be part of this evolving disease is very exciting."

Staff doesn't return calls, staff never identifies themselves when they answer the phone which appears to allow them to be indifferent, uninterested and impatient.
