We started going to Dr. Ganderson when our gastroenterologist was letting my husband's ulceratice colitis get worse without treatment. Dr. Ganderson and his staff are amazing. He really knows what he's doing and I feel as though we are very important to him. He explains all the aspects of the disease in detail and offers a wide variety of treatment options. He also keeps our general practitioner on the up and up and calls us about once a week to make sure my husband is doing well. He's very attentive.
