Dr. Ollington is fabulous! He has helped me so much! I have Crohn's/Colitis. He is always willing to listen to all my issues, make suggestions, refer me for additional tests, and add or change meds when needed. His great sense of humor keeps me upbeat. I am so lucky he is my doctor and really has saved my life with my colon blockage from scar tissue and diverticulitis. His referral to another doctor for my surgery was a life-changing time for me!
