i don't want to complain as overall it was a good experience but I wish the dr. waited for me to come to consciousness to talk to me. i did not remember seeing him at all after the procedure. it was odd to hear 'you already spoke to the dr' when i was not aware of it at all.
I found Dr Dunn to be sympathetic and painstaking. He was thorough in taking down my symptoms and medical history and ensured that the subsequent procedure was comfortable and informative.
I had a colonoscopy and gastroscopy and the whole process went smooth.I was really amazed by the treatment and atention I received from Dr Jason and his team.I would highly recommend it.Thanks a lot
Dr Dunn is a talented & experienced professional in his field. He has helped me overcome issues related to the stomach acid. He's also a nice person.
Calm and thorough
