While in medical school Dr Shear was diagnosed with Ulcerative Colitis, a chronic autoimmune inflammatory condition of the GI tract. This diagnosis has shaped his life and practice but not defined it: “As a GI patient myself with chronic disease, I understand what a lot of my patients are walking through. We each are coming from our own place. I want to help you understand your diagnosis, and proposed treatment plan. In my experience patients who are well informed and partnered in their care do the best. As your GI physician, my simple promise is that I will endeavor to provide the absolute best care that I can. This same promise extends to my medical colleagues who entrust Digestive Care Specialists to their patients’ GI care.” Dr. Shear is thankful for his faith, his beautiful wife and their precious little boy and girl. He is excited to get back to the mountains of Wyoming and serve the great people here.
