About Justin Kosirog, M.D.
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.

Reviews
Very painless and pleasant. All staff were friendly and courteous. Information from the doctor was very helpful and easy to understand.
Great communication. Everyone very professional, the details explaining the whole process step by step very clear. A friendly environment since the moment you arrive, I will recommend the clinic to everyone.
The doctor the nurses were great. The only thing it's lackin It's phone calls so hard to reach someone to get an answer sometimes.
Staff very friendly and professional. Dr. Kosirog very friendly and took time to explain procedures

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.

Great experience. Amazing “bedside manner.” I would highly recommend Dr Kosirog to my friends and family.
Professional, patient, compassionate and a great listener.
Excellent care. Very kind. The best Doctor and his team are incredible. I am very grateful
No complaints. He listens, he takes his time with you in each visit. After procedure he came to discuss things while in recovery, explains things well and I felt like I was in good hands. No complaints regarding office staff or nursing staff at either the office or the surgery center. Office staff is easy to communicate with and answers questions quickly. Definitely plan to stay with this Dr long term for any GI issues.
Everyone at the office was wonderful! The Dr is kind and caring.
I received great communication from the team on all the steps start to finish and the follow up call, I even had the Doctor call me back as I had a separate follow up. Very pleased with the total care and I recommend this team and Doctors
It was a delight and pleasure to meet Dr Kosirog. The whole team was wonderful to work with, very professional. We enjoyed his sense of humor too! We will be back in 3 years
