Dr. Rosenblatt had zero interest in anything my 77-year-old mother had to say during her first and only appointment with him. His demeanor was cold and disinterested.

My Life was saved because of Dr. Rosenblatt. Nothing was helping me. I caught C-Diff, & needed a emergency "Fecal Transplant". ( Which I didn't know could be done) Nothing any of the other Doctors were doing was helping. Had been on all kinds of Medicine & treatments my hopes were gone & empty . I Highly recommend this very smart, caring, compassionate Doctor. He gave me the gift of my Quality of life back. I will forever be grateful for his care & amazing bed side manner toward my concerns & worries. If he hadn't done such a fine job in restoring my bodies ability to be working properly again, I wouldn't be here typing this. There aren't enough words to describe the professionalism I received & his caring staff. 5 Stars to Dr. Rosenblatt & His Entire Team.

Dr. Rosenblatt has met with me twice now. Initially for an outpatient appointment and blood tests and then for an endoscopy. Both times he was professional, courteous, knowledgeable and caring. I am 65 years old and this was my third endoscopy (first one with him), and by far the easiest for me. He is a skilled physician and he works with a skilled and caring team at UC Health/Long's Peak. I also appreciate that he is thoughtful and straightforward. He instilled great confidence.

I can not even start to express how disappointed we are with the level of care we have received from Dr. Rosenblatt. We have been to the ER multiple times from a surgery complication and have been told not to bother until normal business hours. It takes over 3 days to get a response from his office. Its just amazing the lack of care you receive from this Dr. or any other Dr. in his office. A great example of a Dr who cant be bothered amd doesnt care about his patients.

While visiting relatives in Colorado, my husband was admitted to the hospital with health concerns. Dr. Rosenblatt was his gastroenterologist. Dr. Rosenblatt was very professional, efficient, and thorough. He showed genuine care and concern as he explained the situation, made recommendations and completed follow-up care. We highly recommend Dr. Rosenblatt to others.

My husband had 2 colonoscopies scheduled with this doctor. Initially his referring physician had listed as non-preventative. He had a polyp removed his last colonoscopy he did not have cancer. This was updated to preventative. My husband rescheduled and just got a call that he needs to bring $2000 to the appointment since it is not a preventative procedure. Dr Rosenblatt refused to change his diagnosis. Probably gets more money, doesn't care about patient who may end up getting cancer, Greedy.

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!!!

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 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.

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
