Help Locating a Gastroenterologist

I am an 82 year old male who has had IBS-D since before the onset of puberty. Other than my (rather severe at times) IBS I have been a healthy, relatively physically active individual. As with many other IBS sufferers, my social and economic condition have been negatively affected.

Looking for a gastroenterologist

Together with the IBS, my gut generates large volumes of very smelly gas. I can fart almost at will. I have read that this condition may be due to certain types of bacteria in my colon that generate the gas as a by-product.

A local gut doctor I recently saw who has good client references turned out to operate what appeared to me to be a colonoscopy mill.

Is there someone in this group who might recommend a good Gastroenterologist in the North Atlanta area?
