Our experience with Dr. Raja was excellent. He assisted as much as possible to get our procedure approved with the insurance companies. We did not receive the denial of our claim until we had already traveled from Texas to Ohio for surgery. All of the required testing was completed in one day with all services helpful and professional.

I was so pleased to have *Dr. Raja as my surgeon.

Reviewed on Apr 24, 2019

The doctor told me he would talk with me after I awoke from the sedative and tell me and my wife the outcome, answer any questions, etc. When I reminded him that a routine part of my endoscopy was the administration of an amnesiac at its completion, he did not see a problem with this. The care I received was excellent, but I would like to have had a conversation with the doctor myself instead of having to rely on my wife's memory of the conversation. Even though a post-procedure appointment was scheduled in the doctor's office a couple of hours later, only the nurse (nurse practitioner?) was present to explain the outcome to me, answer questions and discharge me I was able to remember this meeting well. But I would like to suggest that the doctor himself show up at this meeting, since I have no recollection at all of the meeting he held immediately post-procedure with me and my wife. This is me suggestion for a best practice.
