Today's very special guest is my good friend Dr. Mark MacMillan. Dr. Mark talks us through his career from University to his role as a Gastroenterologist and Hepatologist at the Dr. Chalmers Hospital in Fredericton, NB. Dr. Mark is very active in the community with the Walk A Mile In Her Shoes marathon. Dr. Mark is also a Star Wars Lego fan like my son Mason. He has a very extensive Lego collection.
