By far one of the best GI doctors.  I just saw Dr.Khodadadian for treatment of my irritable bowel syndrome (IBS) which I have been suffering from for many years.  Rather than just throwing medications at me, he was able to diagnose my years of gas/bloating symptoms as a food intolerance with a series of “breath testing” tests. This is apparently an instrument that allows pinpointing of what things in my diet were causing me symptoms that my other gastro’s that I had been to didn’t offer.  I had always known that certain food substances cause me trouble but it was really helpful to identify exactly which they were.  I am feeling better than I have in a long time thanks to him.
