Dr. Stephen Wangen, co-founder and Medical Director of the IBS Treatment Center, and his staff have been successfully helping people resolve irritable bowel syndrome and chronic digestive problems since 1999. This success culminated in the 2005 opening of the IBS Treatment Center, the first clinic in the nation to focus solely on addressing this debilitating condition.
Over the years the IBS Treatment Center has cared for a wide variety of patients. Some patients have had IBS symptoms so severe that they spent a considerable amount of time in the hospital. Others are no less frustrated with the impact that it is having on their lives. The thread that tied them all together was that they had never seen an IBS expert, a doctor who’s only mission is to help people solve IBS. The IBS Treatment Center is proud to have cured thousands of these patients.
Although the clinics are located in Seattle, Washington and Los Angeles, California, patients come to us from around the country and the world. The map below gives you an idea about how far people will travel to have this condition properly addressed. They have come from every state in the US (other than South Dakota, go figure), and from every occupied continent on earth!
