Suffering from a condition (which had continued for over three weeks), I was treated yesterday for the first time by Dr. Cathleen Cabansag. While my treatment is ongoing, here are my initial reactions. Dr. Cabansag is knowledgeable, thoughtful, careful and thorough. She inspires confidence. Also, I appreciated the efficiency of the San Francisco Gastroenterology staff — they handled the paper work and making a supplemental appointment with ease and without fuss.
