dr. rosenblatt absolutely saved my life. my very first routine colonoscopy revealed 2 very large cancerous polyps on both sides of my colon...as they were large and he was unable to remove them completely but spent quite some time attempting to do so. they sent me home with pics and he diligently called as soon as results were in and we had an office visit and i was referred to dr. le ...a very skilled surgeon. anastomosis removal of my colon and reconnect. year later.. and all is A-ok!

Dr. Mark Rosenblatt is an excellent care provider in every aspect of his job. It feels like it is more than just a career for him because he makes his patients feel like family. That also does not go unnoticed for his caring staff. I have been seeing Dr. Rosenblatt for the better part of five years and would not even consider seeing another doctor. He has fantastic bed-side manner and is very kind, understanding and EMANATES EVERYTHING THAT A DOCTOR SHOULD BE. I could not be more pleased!!!

Very good. Professional and through with his work. Had a large polyp removed and no problem what so ever.

I have had chronic constipation issues most my adult life. Trying every thing possible, I finally went to Dr. Mark and his advice and support has helped me tremendously. Always fitting me in and patiently listening to my problems. I have been to many other Gastro Doc's and they pass me along telling me to take more fiber. Thanks goodness I finally found a doc that listens.

Dr. Rosenblatt has been successful in helping me manage my UC. I've been to a number of Gastro docs but he has a unique insight into getting to heart of the problem very quickly. The smartest thing I did was listen to his instructions exactly how he laid them out. I feel incredibly fortunate to have found him. It's worth the drive to Greeley!

I have been a patient of his for a number of years and have found him to be an excellent Gastroenterologist as he has always listened to my questions regarding my acid reflux situation and continues to work with me in relieving it. He has run test on me and given me not only medications to help controlling it but also suggested dietary changes and exercise to minimize the discomfort. I have been very satisfied with the care has he provided me with and would recommend him to others.

I was referred to Dr. Rosenblatt by a surgeon at North Colorado medical center. Dr. Rosenblatt was very professional, attentive, and caring. He came to my hospital room on a daily basis, and answered questions. I would recommend him to anyone.
in Greeley, CO |
I was surprised Dr. Rosenblatt didn't wait for me to come to after having a colonoscopy and upper scan before leaving the hospital. My next appointment couldn't be scheduled any sooner than a month out. He left me with a prescription at the hospital, which was equivalent to a med I was already taking. I didn't know this until my visit with him a month later. He informed me that I didn't need to be on both meds. All he had to do was read my file to determine what meds I was currently taking.
in Greeley, CO |
Only saw him briefly while prepping then while incoherent and sedated after my procedure. Never contacted me about bioipsy results - I finally got them by calling. I sent two emails and left two phone messages - he never responded. I wouldn't know the guy if we shared a dinner table. Pleasant, albeit aloof, unimpressive - has the air of I've got better things to do I still don't have a definitive answer to my persistent problem and will likely go to another clinic. Wouldn't recommend him
