Dr. Barker was my chemo physician in 2004. He was an excellent doctor and I trusted him with my treatment at the time. Going through treatment is a tough situation to begin with and it helped knowing that he had so much experience and knowledge. He also has a good sense of humor which helped when I was going through a rough time. I was burned badly in radiation (he had nothing to do with this) and he took me out of treatment immediately. I would not ever hesitate to recommend him to anyone.
