Why Gastroenterology?
I have a family member with celiac disease which for first piqued my interest in the field of gastroenterology. From there, I grew to love all the different disease processes including IBD, liver pathology, and celiac disease to name a few. I also love performing endoscopy. I am also board certified in Emergency Medicine and have an interest in emergent procedures for GI bleeding, food bolus, sigmoid volvulus, etc.
What Can Patients Expect?
Patients can expect a physician who cares for the individual and who treats all individuals with respect and kindness and is thorough and diligent.

I had to return in a year for another colonoscopy. Drinking the prep was easier this time Miralax, Gatorade, and Magnesium Citrate. Dr. Kosirog is awesome. The procedure was done at St. Joseph’s Hospital outpatient. Everything went well and was handled very professionally. I would highly recommend Dr. Kosirog.

The nurse that got me prepped was great. Dr. Kosirog came in and introduced himself to me, he was very pleasant and professional. The nurse anesthesiologist had me out in a flash. All in all everything was handled very professionally and efficiently.
