      I made this appointment as a follow up to In the hospital for three days with a partial blockage in my small Intestine. I had many questions and concerns. Dr. Kobashi had taken the time to read all my test results and hospital care notes before my visit and was prepared to discuss my situation and answer all my questions. He was diligent, thorough, and patient with my questions. I really appreciate the time he spent with me. We developed a plan for proceeding based on my concerns about what happened and how I might be able to prevent It in the future. His care was outstanding!
