Made me feel more relaxed than the first doctor I went to. who gave me all the gory details and telling me I needed surgery or radiation and explaining all the side effects and telling me to make a decision. Doctor Cauldwell wanted me to see and ear nose and throat doctor as well as a neurologist to rule out some of the symptoms that I'm having that are possibly unrelated to the tumor before making any decisions. I felt he was very professional, informative and took on a great approach to making me feel more comfortable and less scared.
