Avoid Dr Mark Richardson if you want a competent Dr, especially if you or your loved one has pancreatic cancer, claims to have extensive experience as a surgeon and with pancreatic cancer, don't believe him, please go get a second opinion, can't admit he doesn't know what to do and, has no duty of care, he won't offer or suggest a second opinion, hate giving him a one star rating, deserves no stars, but have to give 1 to give a review. Avoid this Doctor
