I was very impressed with Dr. D and his staff!! He had read my chart prior to my visit and knew exactly why I was in his office. He recommended an endoscopy which I have just had. That too was done efficiently. I am VERY impressed not only with the Oregon Clinic, but also with the Providence Health Care system.

Unfortunately I have had several bad experiences with specialists, but I am so grateful to have found Dr Deenadayalu. He is very sharp and is quick to figure things out, but he also had such a great bedside manner. He is soft spoken and genuinely listens to you. He has even shown concern and asked me about medical issues that do not pertain to my Celiac Disease. I have been seeing Dr Deenadayalu since 2013 and recommend him too all of my friends and family that have to see a GI Specialist.

Dr. Deenadayalu is a highly intelligent, caring, and compassionate individual. It was obvious he had thoroughly reviewed my medical records and came up with a logical care plan. He often calls me personally with lab results. He has helped me tremendously with my Crohn's disease. I would highly recommend him!

Great doctor. Excellent bedside manner. Explained things with clarity. Very happy with my interaction. Would highly recommend. I suspect patient review below may be from someone incapable of handiling her own life stressors and so she takes them out on her physicians because nothing she mentioned seems accurate in my experience with this doctor.
