"Dr Stassen has been a very good doctor for me. He quickly diagnosed an unusual gallbladder problem and later a malignancy. He is always gracious and attentive, remembers my family members, and has been a great help over the past decade. He was highly recommended by my previous specialist, and I have been pleased. Sometimes the office organization at Austin gastro is slow, but I have had a great experience as Stassen's patient."
