Dr. Dunzendorfer is an amazing doctor. He is extremely compassionate, intelligent, efficient and methodical in his practice. I had a colonoscopy and endoscopy performed on the same day and everything went smooth from start to finish. I would recommend him to anyone.

Does not spend any time with you. After my procedure, I read reason for colonoscopy: diarrhea. Never had/complained about this. It was supposed to be for constipation. He took several biopsies for colitis! This is the medical term for diarrhea. Also was having severe upper/lower pain. I asked for an endoscopy. He said, "That's not what you complained about." Before I could say anything else, he is scurrying away. I asked, "What about this pain? And where do I go from here "? Not wanting to answer, he said, "See a g.y.n." I did with no avail. Still in chronic pain. Now going back to my primary. I do not recommend any female to seek this dt. He has a very rude disposition.
