This Dr. seems to be a complete professional from my one experience so far. I would recommend him to a friend or family based on what I know so far and my experience of his treatment of my spouse.

I have had a very good experience with this Dr. and his office staff so far. My previous Gastro Dr retired and Dr. Assioun is very thorough and answers any questions I have about my care or condition. I would recommend anyone to this professional
in Torkington, MO |
Dr. Asioun was able to see me the day I called to make an appointment which is very unusual for specialists . He was able to squeeze me in for a colonoscopy in 3 days after I saw him in office. He is very knowledgeable and friendly and drew a picture to help me understand my problems with my bowels and stomach. I never had to wait until the next day before his office respond to my calls and questions. Highly recommend him to family and friends

This dr is one of the best doctors I have seen. I see several other specialists for multiple medical problems.Dr. youssed Assioun is very thorough. I went to see him for my acid reflux problems but he also addressed other issues that no other doctor have ever informed me about. He diagnosed me with a chronic liver disease and started evaluating my anemia that I had for several years and was not aware of. He asks about small details. I cant remember seeing a doctor who listens to me as much.
in Festus,MO |
Great experience. Dr spent time listening to me and answer all muconcerns. More than I would expect Very proffesiinal staff. Dr saw me few minutes before my appointment time.
in St Louis, MO |
Saw Dr. Assioun at Mercy Clinic Gastroenterology-Jefferson. If you would like to be rushed through the office and the visit, not even having time to fill out your paper work, then not being able to get a quote for the EGD that they scheduled and have Dr. Assioun not send in the prescription to your pharmacy that he said he would and receive a $375 office visit bill for essentially a 20 minute visit with blood pressure reading then I would highly recommend Dr. Assioun and his office. What a joke.
