I went in to see Dr. Marzulo at his Phoenix location. The office area was very clean and comfortable. Dr. Marzulo greeted me right away and brought me into the exam room. He was very thorough and asked me various questions and was very personable. I felt confident with his diagnosis and could tell he was very knowledgeable of what factors causes some people to get headaches/migraines and ways to address them if it becomes a concern. I highly recommend him and would see him again if I get any symptoms.
