Dr. Armstrong was a wealth of knowledge explaining my current plan of care and next steps. She stated that she reviewed my file with a fine tooth comb before making recommendations. This made me feel more comfortable with her interpretation and advice. The PA assisting, "the boss", as he referred to her was very compassionate and knowledgeable as well.
