I had my third colonoscopy with Dr. Devarajan today. He's simply the best. Extremely competent and knowledgeable. You know you're in good hands with him. He has clearly done literally thousands of these before. The procedure is quick and painless. His overall facility is efficient, friendly, and supportive. The staff is wonderful--true caregivers.

Dr. Raj did an excellent job with my 5 year colonoscopy. He made this procedure very comfortable before and after. His note of details was also significant. He noted something that may be insignificant but has given a follow up to ensure there are not any issues. He is a true practicioner!

I've been going to Dr. Devarajan for several years now and each time I go, for either a colonoscopy or endoscopy, I always feel so taken care of. Dr. Devarajan takes the time to know the full picture of your health situation and is very good about explaining options for medications and/or follow-up care. Also, Dr. Devarajan's whole team is very caring and professional. I feel very fortunate to have such excellent health care.

I have had Dr. Devarajan for many years and this was the first time I had my colonoscopy at his center and it was the best experience. The last time I had it at a hospital and it took hours upon hours. Not this time I was legit there for 1.5 hours. The nurses, the anesthesiology and the doctors tech was fantastic.

The admission process, although "screened" is not private. They ran like clockwork, which is good because you don't want to be delayed, but you don't get the personalized service feeling as everyone is just in the waiting room being called one by one. Staff is nice.

I am currently seeing Dr. Devarajan for evaluation of symptions of Diverticulosis and Diverticulitis symptions spanning over a year with no relief from other Physicians. Dr. Devarajan is pleasant, understanding, asks questions relating to my issue and shows interest in finding me a diagnosis and relief. I am very confident that Dr. Devarajan will find me relief with his diagnostic testing.

After my initial visit, in which he ordered 8 or 9 blood tests, and rook 3 weeks to review the results. His assistant called with the results, which were as follows: "You have cirrhosis" that was the entire conversation. I heard nothing from the doctor.

Had a problem with gall bladder pain. Seen other doctors but fortunately was able to see Dr. Devarajan and he is truly a gifted and caring doctor. He immediately got me in for an endoscopy within a day, and scheduled an appointment with a surgeon the same day. Best doctor around.

Dr Devarajan is an extremely competent doctor. However, they do not schedule well. I arrived at 10:40 as directed because my colonoscopy was scheduled for 11:10. I finally had the procedure at 1:15. I was not told anything about the delay. I was hungry, tired, and anxious waiting for hours. The nurses were not very informative or helpful. The only person who reassured me and spoke with me was Ary-Lex and I am very appreciative of his support because I wanted to get up and leave.

I was sent to see Dr. Devarajan to remove a very large but difficult polyp to be removed. Dr. Devarajan was the only one who was able to safely remove it. Other doctors did not feel comfortable removing it. If it weren’t for him it would’ve turned into cancer. I would definitely recommend Dr. Devarajan

This man is not a good doctor. All he did in the years I went to him was push more omeprozole on me. When I told him I didn't want to take it anymore because I was just getting worse he told me there was nothing else he could do for me. The first thing my new doctor did was take me off the omeprozole and I feel much better.
