Dr McLean didn't listen to me or address my concerns nor did he provide an effective treatment plan. I was misdiagnosed which led to serious health issues, hospitalizations, surgeries, suffering and irreversible damage. He does not appear to have any understanding (or care/interest) in pancreatic issues. My intense pain was not addressed and I was left to suffer.
